Patrick Galbraith - Oracle

MySQL is the world's most popular open source database and Kubernetes is the most popular and rapidly-developing project currently. The purpose of this talk is to explain and demonstrate how running a complex stateful application such as a database is made easier using Kubernetes and that there are a number of options available.

MySQL deployment patterns covered will start with explaining simple how to run MySQL with a simple command using a helm chart; onto how a MySQL asynchronous replicated master/slave MySQL pattern works on Kubernetes; onto how several different MySQL operators can be used giving a detailed discussion; and demonstration will showcase the Oracle MySQL Operator which uses group replication and the MySQL router, and makes creating MySQL clusters, backups, and restorations trivial.

Last to be covered will be project Vitess which is used for horizontal scaling of MySQL which has numerous benefits such as built-in sharding and shard management, connection-pooling, query sanitization.

Baron Schwartz - VividCortex

It's easy for modern, distributed, high-scale applications to hide database performance and efficiency problems. Optimizing performance of such complex systems at scale requires some skill, but more importantly it requires a sound strategy and good observability, because you can't optimize what you can't measure. This session explains a performance measurement and optimization process anyone can use to deliver results predictably, optimizing customer experience while freeing up compute resources and saving money.

The session begins with what to measure and how; how to analyze it; how to categorize problems into one of three types; and three matching strategies to use in optimization as a result. It is a recursive method that can be used at any scale, from a data center with many types of databases cooperating as one, to a single server and drilling down to a single query. Along the way, we'll discuss related concepts such as internally- and externally-focused golden signals of performance and resource sufficiency, workload quality of service, and more.

Alexander Rubin - VirtualHealth

Running an analytical (OLAP) workload on top of MySQL can be slow and painful. A specifically designed storage format ("Column Store") can significantly improve analytical queries' performance. There are a number of opensource column store databases around. In this talk, I will focus on two of them which can support MySQL protocol: MariaDB ColumnStore and ClickHouse.

I will show some realtime benchmarks and use cases, and demonstrate how MariaDB ColumnStore and ClickHouse can be used for typical OLAP queries. I will also do a quick demo.

Jeff Duffy - Amazon Web Services

Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. In this tech talk, we will introduce Amazon DocumentDB and its unique architecture that makes it easy to run, manage & scale MongoDB-workloads in the cloud. Amazon DocumentDB is designed from the ground-up and uses a unique, distributed, fault-tolerant, self-healing storage system that automatically scales storage. Additionally, with Amazon DocumentDB's architecture, the storage and compute are decoupled, allowing each to scale independently. Through common use cases, we'll discuss why this architecture helps developers reach faster to their business needs. We'll also talk about how developers can use the same MongoDB application code, drivers, and tools as they do today to run, manage, and scale workloads on Amazon DocumentDB without having to worry about managing the underlying infrastructure.

It's 2019 and there are so many choices for storing your data. There are old players on the market and there are some new kids on the block. Making the wrong choice for your database can effectively sink your product, project and even your reputation! Should you go with SQL or NoSQL or Document database or something in between? What about polyglot persistence? Reactive, event-driven, non-blocking, async applications? What about the language bindings? What about support? Performance, Tuning, Tooling, Monitoring, Observability, Upgrades, Rollbacks, Migrations, Search & Indexing, Analytics, Availability, Durability, ACID or BASE? Building, running & maintaining storage infrastructure is non-trivial. We will look at the state of databases in 2019 and try to answer some of these questions.

Josh Berkus - Red Hat

You can have fully automated high availability PostgreSQL on your Kubernetes cluster ... today. The Patroni system for automating PostgreSQL deployment, failover, and migration is ready to use and in production in several places. In this live demo session, we will show you how you can make use of this technology.

We will run though setting up PostgreSQL clusters, both using basic Patroni and using a PostgreSQL Operator. We will then demonstrate failover and disaster recovery, go over some basic configuration options, show how security & authentication works, and explore some plugins and options. After that, you'll learn about the current state of the Patroni project as well as what the alternatives are.

If you need to administer more than one PostgreSQL replication cluster, you'll want to see how Patroni and Operators can make your daily DBA headaches and 2am wakeups go away.

Marco Tusa - Percona

We in Percona are constantly looking at how we can help our customers to have the right solution at the right time. We are constantly looking to identify the right tool for the job.

In our constant research we identified that migrating from Oracle, MS SQL or any other closed source data platform, is becoming more and more relevant for large organizations.

The maturity reached by open source solutions, the large adoption of those solutions in medium size companies or for new projects, in conjunction with the agility they have to adapt platforms to newer and more modern needs, had finally led large organizations/enterprises to understand that "It can be done".

Still the journey from closed source to open source is not always a walk in the park.

There are many factors that must be considered and analyzed, to successfully migrate.

There are simple situations, where a simple data migration with few schema adjustments is enough, and much more complex scenarios where to migrate, the whole logic must be reorganized.

Finally, there are situations where migrating is simply not possible or valuable.

Having a clear path that can help you to assess what is what, and how much effortis needed for each case, is gold. Literally, because it will allow you to focus on what makes sense, and the right effort and resources.

The scope of this presentation is to illustrate how we in Percona perform that assessment, and what is our methodology to assist our customer to successfully decide how and if to migrate.

Luís Soares - Oracle

The evolution of MySQL replication shows that there is a lot of effort put into reducing operations cost and minimize administration overhead. Thus MySQL DBAs and DevOps can spend more time expanding their infrastructure, rather than catering for it.

Many different areas have been enhanced. For example security, operations, fail-over, observability, failure detection, consistency, split-brain protection and primary election, flexible replication workflows and more.

This session highlights the new replication features in MySQL 8.0. Those that were released pre and post-GA. Come and learn, directly from the engineers, how the new features help you operate, sustain, and extend your MySQL Replication infrastructure.

Seppo Jaakola - Codership

MariaDB 10.4 will come with new Galera Replication version 4. This presentation will outline the new features of Galera 4 Replication as present in MariaDB 10.4 and share the early user experiences with it.

Galera is a generic replication plugin, making it possible to deploy synchronous multi-master cluster topologies with database servers supporting Galera Replication plugin API (i.e write set replication, wsrep API) . Currently both MySQL and MariaDB servers have Galera Replication support, and today there are thousands of MySQL and MariaDB based cluster installations, around the world, processing production system loads in bare-metal or cloud deployments.

With Galera 4, MariaDB 10.4 cluster further extends the capabilities of the synchronous Galera replication. The most prominent feature in Galera 4 version, is streaming replication technology, which implements distributed transaction processing within the cluster. With streaming replication, a transaction can be launched to execute in all cluster nodes in parallel. With this, a large transaction can be executed in small fragments due out the transaction life time, and cluster will not choke with the replication of one large transaction write set, as happened in earlier Galera Cluster versions.

Streaming replication works as a foundation for many more features, to be released in short term. e.g. XA transaction support will now be possible thanks to streaming replication technology.

Alex Cercel - Rackspace

The changes that MongoDB are bringing to the world in 4.0 are tempting to many companies and administrators, but if you are on an older version such as 3.2, upgrading with minimum disruption can be challenging.

Some of the problems that a company might face are that older language drivers versions may not be compatible with newer versions of mongo, the upgrade path might change, and there is a lot of documentation to read before you embark on the upgrade path.

If in 3.2 the config servers could be both mirrored or replica sets, in 3.4, it's a must to have the config servers as replica sets. Upgrading without interruption can be difficult. With so many things to read about, it's always good to have a reference that will give you an understanding of things that you should consider. A form of cheat sheet.

In this 50 minutes session, I would like to present the steps needed to move from 3.2 to 3.4, which will include some tips to upgrade the config servers to replica sets with minimal disruption and from 3.4 to 3.6 and from 3.6 to 4.0, again, with minimal disruption.

The session will also mention best practices that will apply when running any version upgrade.

Morgan Tocker - PingCAP

When evaluating if a new database is a fit for your organization, it can pay to be risk-averse. In this talk, I will demonstrate how you can replicate from MySQL to TiDB and evaluate for performance and correctness initially only as a read-only slave -- reducing the risk of evaluating TiDB.

I will then demonstrate how MySQL can be set up as a replica of TiDB, with the ability to fail-back if any problems are discovered when it becomes a master.

As we move through each step in validating TiDB, you may be familiar with some of the tools being used (mydumper, pt-upgrade, ProxySQL). One of the great parts about speaking the MySQL protocol is you benefit from the ecosystem surrounding it.

Levi Junkert - SmithRx

With the advent of the Health Insurance Portability and Accountability Act (HIPAA) of 1996 all entities that handle health information are required by law to secure all data which contains personally identifiable information (PII) and private health information (PHI). Fines for leaking this data can range from $100 to $50,000 per leaked record. A data breach or leak is extremely costly for both the patients as well as the companies that are entrusted with their PHI. In our presentation we introduce Gonymizer, a tool that is written in Go at SmithRx to handle the anonymization of PHI and PII data from our production database instances.

This data is anonymized and loaded into non-production environments to allow us to use representative data to develop and test against. This makes anonymization of sensitive information quick and simple using a simple column map that is defined in a single JSON file for your dataset. There is a selection of custom processors that we have built to handle basic tasks, such as: first and last name anonymization, changing data to fake locations such as: street addresses, cities, zips, and states. The interface for building processors is also completely extendable and anyone with basic Go experience should be able to build processors that can anonymize your data efficiently. We will also show how this tool decreases our development time for new features as well as simplifying testing in a compliant environment with non-sensitive data sets (HIPAA, PCI, etc).

Toward the end of our presentation we will be discussing how we built our infrastructure using Docker to containerize Gonymizer and schedule anonymization and loading of our test environments using Kubernetes. This talk is targeted for anyone working in the healthcare space where collected data contains PHI and/or PII and is regulated by HIPAA.

Either because of a new feature, a bug, or just for archival purposes, it is often necessary to update or remove large amounts of documents in production.

The challenge with this type of operation is not only to design an efficient process query-wise, but to be able to execute it in production without debilitating the servers or causing secondaries to lag.

There are strategies that can be used to create highly controlled write processes that could run for days under the radar, getting the job done without greatly impacting your application's performance.

In this session, I'm going to share with you key points to consider when creating massive write operations in MongoDB, examples of real-life processes executed, and a few lessons learned.

PostgreSQL performance varies between different releases. Every new version comes with added features and performance improvements that help the growing adoption of PostgreSQL. All these continuous These ongoing developments and improvements drive us to plan on upgrading our PostgreSQL environments, but that's not always an easy task. A few common concerns when it comes to upgrading PostgreSQL are extended downtime, converting the tables partitioned using triggers to declarative partitions, the search for the safest options to upgrade and the effort required in the upgrading process itself. In this talk we'll discuss the variety of options available that can help you upgrade your PostgreSQL servers in the best possible way.

This talk includes:
1. The most significant performance improvements in recent PostgreSQL versions including PostgreSQL 11 and 10.
2. A summary of features that have been implemented with every new version since PostgreSQL 9.1.
3. What is it that you need to consider before upgrading your PostgreSQL server.

This talk will focus on the self-managed nature of Uber's database monitoring and how we've leveraged our open source time series database M3DB to support massive multi-region scale and high cardinality monitoring.

We'll cover how we monitor applications, databases, and their interactions and how we automatically setup application specific dashboards and alerts. This includes things like the ability to alert on metrics like P99 latency and slow queries for a given application at the per-table and per-query level.

Of course, automated and fine grained monitoring requires the ability to ingest, persist, and query massive amounts of high cardinality time series data. We'll talk about the architecture of M3DB and how we've leveraged it at Uber to scale our monitoring systems to billion of unique time series and 10s of millions of data points per second.

We'll conclude the talk with an overview of our Prometheus and Kubernetes integrations, explaining how you can start leveraging M3DB for your own workloads. Finally, we'll give a brief overview of our plans to evolve M3DB into a general purpose, horizontally scalable event store.

John Schulz - The Pythian Group

Modern relational databases are all tied together by a well-defined standard for SQL, the latest version published in 2016. But not all SQL implementations follow the standard and even when they do, they often embellish on it and users tend to use the features they see available to them. As a result, migration between databases tends to be a challenging task. In this talk I will give some examples of database migrations I have participated in over the last twenty years and what issues we ran into with each. I will also talk in a more general sense about:
• Database only migration vs application refactoring - which is likely to have the better ROI?
• Analysis tools to help perform migration like Amazon's DMS, SQLines and DBconvert
• Database agnostic replication
• What it means to get support in the Open Source world and how to get it.

GTIDs were introduced to solve replication problems and improve database consistency.

When, accidentally, transactions occur on a replica, this introduces GTIDs on that replica that don't exist on the master. When, on a master failover, this replica becomes the new master, and the corresponding binlogs of the errant GTIDs are already purged, replication breaks on the replicas of this new master, because those missing GTIDs can't be retrieved from the binlogs of this new master.

This presentation will talk about GTIDs and how to detect errant GTIDs on a replica (before the corresponding binlogs are purged) and how to look the corresponding transactions in the binlogs. I'll give some examples of transactions that could happen on a replica that didn't originate from a primary node, explain how this is possible and share some tips on how to avoid this.

Basic understanding of MySQL database replication is assumed.

From the very beginning, TiDB was designed with the combination of Hybrid Transactional and Analytical Processing (HTAP) workloads in mind. However, since TiKV stores data in a row-oriented fashion, you may have been left wondering how well suited that is for analytics?

In this talk, I will introduce TiFlash which is a native extension of TiDB that offers column-oriented storage to speed up heavy-duty OLAP queries. I will then go over the architecture and some of the design decisions, and how you will be able to use it for your next generation data processing needs.

In the past few years, Postgres has advanced a lot in terms of features, performance, and scalability for many core systems. However, one of the problems that many enterprises still complain of is that its size increases over time which is commonly referred to as bloat. EnterpriseDB is leading a community effort to build a new storage system for Postgres called zheap, which will provide better control over bloat. This session will discuss:

* The objectives of the initiative including better control over “bloat”, eliminating write amplification in most cases and reduction in on-disk storage size of Postgres databases
* Technical architecture of the new storage system including contrasting the new design with the current implementation in Postgres today
* Current status of the project, including the introduction of a new storage management interface, undo handling and when zHeap will be released as part of Postgres.

Near the end of 2018, Amazon announced they would be completely off Oracle by the end of 2019; replacing Oracle's database products with their own AWS-based services. Interestingly, Amazon's move to run entirely on it's own, internally operated data services is consistent with a “desire” voiced by many large companies we've spoken to over the past 18 mos. A major impediment for these companies to move forward, however, is that they want their databases to operate in their own data-centers, be open-source, and deploy-able/operable as a Cloud-Native, Database-as-a-Service (DBaaS) offering. How can a company deploy/operate data services that satisfy the requirements they currently address with their proprietary database portfolio? In Amazon's case they are moving forward by replacing proprietary database software with a combination of AWS DynamoDB and Aurora for transactions. For data warehousing, Amazon is using a combination of AWS Redshift and Athena. Are their existing alternative, open-source projects for each of these components? In the case of DynamoDB and Aurora, yes, the Apache Cassandra and MySQL/MariaDB projects can be used for this purpose. For data warehousing, PrestoDB and the Apache Impala projects can be used in place of Athena and Redshift. All of these depend on a combination of the following additional data services: local caching, event streams, and a REST-based object store. Enter Rockset's RocksDB-Cloud. For the past year, we have been working to enable MariaDB and Percona's MySQL distribution to extend their respective distributions of Facebook's MyRocks storage. The RocksDB-Cloud library is configured to load the RocksDB-Cloud library, which is binary-compatible RocksDB; extending it with support for local caching as well as maintaining a consistent image over an event stream and an Object Store “bucket.” An instance of MariaDB/MySQL operates against local storage (aka the "cache”). The instance's WAL is mapped on to an event stream and a consistent copy of its LSM-tree is maintained in the bucket. In 2019 we are looking to extend this approach to Cassandra and Postgres using the PGRocks and Facebook's Rocksandra projects respectively. Why Intel? The local cache and event stream capabilities of the architecture described above map nicely on to Intel's upcoming Optane DC Persistent Memory product. The use of a REST-based object store affords many opportunities to cost-optimize warm data that needs to remain online but accessed with decreasing frequency over time. As for data warehousing, AWS's Redshift and Athena exploit Amazon's s3 object store. The idea here is similar in that the REST-based object store presents an s3-compatible interface to Impala and PrestoDB as well as exploits the solution's local caching capability. What other technologies enable this solution? First and foremost is availability of low cost, relatively low latency, high bandwidth networking that can be employed as scalable cluster interconnect with full bisection bandwidth. Secondly, an Orchestration/Scheduling framework based on Kubernetes (k8s) has emerged as a key enabler. We combine k8s with cluster-wide software defined network (SDN) and software defined storage (SDS) implementations to fully exploit the resources available within the physical cluster. Finally, we employ the Vittes-Based Database-as-a-Service (DBaaS) framework to manage databases operating over the cluster. In this talk, we'll briefly review the architecture. We'll then discuss the current implementation with particular focus on the trade-offs we made for the local cache, the WAL/event-stream, and the REST-based object store. We'll end the talk with a discussion on plans for 2019 and beyond.

Optimizing MySQL performance and troubleshooting MySQL problems are two of the most critical and challenging tasks for MySQL DBA's. The databases powering your applications need to be able to handle heavy traffic loads while remaining responsive and stable so that you can deliver an excellent user experience. Further, DBA's are also expected to find cost-efficient means of solving these issues.In this presentation, we will discuss how you can optimize and troubleshoot MySQL performance and demonstrate how Percona Monitoring and Management (PMM) enables you to solve these challenges using free and open source software. We will look at specific, common MySQL problems and review the essential components in PMM that allow you to diagnose and resolve them.

When your SQL query reaches the DBMS, it's the optimizer's job to decide how to execute it for you to get the result as fast as possible. To make this decision optimizer can examine the actual table data, but with multi gigabyte and terabyte tables, the only practical solution is to use various data statistics that were collected in advance. The better the statistics and the more precisely it describes the actual data, the faster the plan will be, because the optimizer image of reality will be closer to the actual reality.

In this talk you'll learn what data statistics MariaDB and MySQL can collect, what statements do that, how to tell the optimizer to use it (it won't necessarily do it automatically!) and how it can make your queries many times faster.

And, of course, when not to use indexes, when up-to-date statistics is enough.

When it comes to choosing a distributed streaming platform for real-time data pipelines, everyone knows the answer: Apache Kafka! And when it comes to deploying applications at scale without needing to integrate different pieces of infrastructure yourself, the answer nowadays is increasingly Kubernetes. However, with all great things, the devil is truly in the details. While Kubernetes does provide all the building blocks that are needed, a lot of thought is required to truly create an enterprise-grade Kafka platform that can be used in production. In this technical deep dive, Viktor will go through challenges and pitfalls of managing Kafka on Kubernetes as well as the goals and lessons learned from the development of the Confluent Operator for Kubernetes.

Loki is a horizontally-scalable, highly-available log aggregation system inspired by Prometheus. It is designed to be very cost effective and easy to operate, as it does not index the contents of the logs, but rather labels for each log stream.

Loki initially targets Kubernetes logging, using Prometheus service discovery to gather labels and metadata about log streams. By using the same index and labels as Prometheus, Loki enables you to easily switch between metrics and logs, enhancing observability and streamlining the incident response process – a workflow we have built into the latest version of Grafana.

In this talk we will discuss the motivation behind Loki, its design and architecture, and what the future holds. It's early days, but so far the response to the project has been overwhelming, with more the 4.5k GitHub stars and over 12hrs at the top spot on Hacker News.

Loki is an opensource project, Apache licensed.

With the amount of stored data growing quickly, analytics work has turned into a very intensive workload that will hit our MySQL servers in very hard way.

During the last few years we have seen a bunch of new engines designed to digest big portions of data and help with analytical queries. Now there is a new contender in the arena that claims to be MySQL Compatible, High Impact and Open Source Analytics.

During the course of this session we will go through each of these topics and try to answer:
- Compatible - how hard it is to take data out of MySQL and how much lag it may suffer on real workload?
- High Impact - near real time query response, low cost of entry high ROI?
- Open Source - open source only?

Moreover, we will compare the solution against some other popular products already in the market like ColumnStore, Cassandra, Clickhouse and we'll see how TiDB behaves in comparison.

MySQL, as a database, strives on a filesystem but not all filesystems are equal! On Linux, ZFS is gaining attention and there are good reasons for that, especially if you happen to also run MySQL. In this talk, I'll describe the main characteristics and features of ZFS and draw parallels with the architecture of InnoDB. From easy backups to compression and improved caching, you'll see that MySQL has a lot to benefit from ZFS. I'll discuss the configurations of both MySQL and ZFS so they play well together and perform at their best. Finally, cost saving MySQL/ZFS reference architectures using both, bare metal and clouds servers will be presented and reviewed.

FoundationDB is a distributed database designed to handle large volumes of structured data across clusters of commodity servers. It organizes data as an ordered key-value store and employs ACID transactions for all operations. Document Layer is a stateless micro server on top of FoundationDB that allows management of JSON documents at large scale. It exposes the traits of FoundationDB through document data model, such as fully ordered documents, consistent indexes, and serializable transactions. It does all this while maintaining wire compatibility with MongoDB® API. As the compatibility is done at wire level, existing MongoDB® tools and drivers work seem less. In this talk, we explore how FoundationDB core strengths play well together with the document data model to make it an easier to use and reliable database.

Would you like MySQL Protocol Compatibility and near real time dashboard analytics with that?

We are hoarding data in the hopes of making meaningful information out of them to make smart business decisions. But we also resort to inflating costs just to satisfy this need (or not). While there have been a number of open source roll your own options, it has been also operationally costly and sometimes stressful to maintain, not to mention the shortcomings of each. If you have been traditionally storing your data with MySQL and have been enduring running your queries from the same set of servers, fret no more - Clickhouse might just be what you need. In this presentation, we will discuss how to deploy, design, and maintain a Clickhouse analytics platform that continuously reads data from your MySQL servers in near real-time*.

As modern organizations have rapidly embraced containers in recent years, stateful applications like databases have proven tougher to transition into this brave new world than other workloads. When persistent state is involved, more is required both of the container orchestration system and of the stateful application itself to ensure the durability and availability of the data.

This talk will walk through my experiences trying to reliably run CockroachDB, the open source distributed SQL database, on Kubernetes, optimize its performance, and help others do the same in their heterogeneous environments. We'll look at what kinds of stateful applications can most easily be run in containers, which Kubernetes features and usage patterns are most helpful for running them, and many, many pitfalls I encountered along the way. Finally, we'll ponder what's missing and what the future may hold for running databases in containers.

The Player Accounts team at Riot Games needed to consolidate the player account infrastructure and provide a single, global accounts system for the League of Legends player base. To do this, they migrated hundreds of millions of player accounts into a consolidated, globally replicated composite database cluster in AWS. This provided higher fault tolerance and lower latency access to account data. In this talk, we discuss this effort to migrate eight disparate database clusters into AWS as a single composite MySQL database cluster replicated in four different AWS regions, provisioned with terraform, and managed and operated by Ansible.

This talk will briefly overview the evolution of the player accounts services from legacy isolated datacenter deployments to a globally replicated database cluster fronted by our account services and outline some of the growing pains and experiences that got us to where we are today.

In this talk, we discuss the use of the open source MySQL Community Edition and Percona Server projects and Intel's Cascade Lake server platform as the primary building blocks for hosting a Database-as-a-Service (DBaaS) deployment. Data demonstrating the advantage of this configuration will be presented. Emphasis will be on deployment of an offering that provides developers with self-service, on-demand delivery of databases that run over shared infrastructure in a multi-tenant environment. Demand for DBaaS from a diverse span of market segments has driven the large Cloud Service Providers to invest in the buildout such offerings.

Today, these offerings are widely available from Multiple Cloud Providers. Until recently, however, organizations wanting to provide DBaaS from within their own data centers were left without good options. This demand is set to be addressed with the emergence of several open source projects. A second, intersecting trend is the imminent release of Intel's next-generation Cascade Lake XEON platform and its support for byte-addressable, persistent memory via the Intel® Optane™ DC Persistent Memory product.

Our talk will dive into the intersection of these two trends starting with an overview of the Cloud Native DBaaS model. Next, a concrete description of a deployment model using Percona's MySQL and MyRocks distributions will be introduced. This model will be supported by a two-fold, data-driven discussion on performance and density. First, a performance characterization for both the InnoDB and MyRocks storage engines is presented with the focus on comparing/contrasting the use of NVMe vis-a-vis Intel® Optane™ DC Persistent Memory. For the latter, we include Intel® Optane™ DC Persistent Memory volumes in fsdax as well as sector modes. Secondly, data on database instance density using a single Intel Cascade Lake server outfitted with NVMe vis-a-vis Intel® Optane™ DC Persistent Memory will be presented. The talk will conclude with a discussion on the results and how they have influenced our plans for further work in MySQL CE/Percona Server open source projects going forward.

MySQL and MariaDB have a long list of old, potentially trivial bugs that are annoying if you hit them. No one's really bothered to fix them, so why not you? It doesn't take a large amount of C/C++ knowledge to pick out an old bug, and build/test a MySQL/MariaDB patch to fix an old bug.

I'll talk about what is a sane choice of bug, how to use the existing mtr to help, small test cases, and packaging up and submitting your changes.
