Art Van Scheppingen - vidaXL, Bart Oles - Severalnines AB

Over the past few years, VidaXL has become a European market leader in the online retail of slow moving consumer goods. When a company achieved over 50% year over year growth for the past 9 years, there is hardly enough time to overhaul existing systems. This means existing systems will be stretched to the maximum of their capabilities, and often additional performance will be gained by utilizing a large variety of datastores.

Polyglot persistence reigns in rapidly growing environments and the traditional one-size-fits-all strategy of monoglots is over.

VidaXL has a broad landscape of datastores, ranging from traditional SQL data stores, like MySQL or PostgreSQL alongside more recent load balancing technologies such as ProxySQL, to document stores like MongoDB and search engines such as SOLR and Elasticsearch.

PostgreSQL 11- Bruce Momjan
PostgreSQL benefits from over 20 years of open source development and has become the preferred open source relational database for developers. PostgreSQL 11 was released on October 18. It provides users with improvements to overall performance of the database system, with specific enhancements associated with very large databases and high computational workloads.

MongoDB 4.0- Alexander Rubin
Do you love MongoDB? With version 4.0 you have a reason to love it even more! MongoDB 4.0 adds support for multi-document ACID transactions, combining
the document model with ACID guarantees. Through snapshot isolation, transactions provide a consistent view of data and enforce all-or-nothing execution to maintain data integrity. And not only transactions - MongoDB 4.0 has more exciting features like non-blocking secondary teads, improved sharding, security improvements and more.

MariaDB 10.3- Arjen Lentz
MariaDB benefits from a thriving community of contributors. The latest release, MariaDB 10.3, provides several new features not found anywhere else, as well backported and reimplemented features from MySQL."

Every new version of MongoDB comes with exciting new features and a lot of improvements and version 4.0 couldn't be an exception to this rule. An upgrade from previous versions will unlock long waiting features like transactions but at the same time without proper planning could be catastrophic for your organization.

This presentation will guide you through the stapes for planning and implementing an upgrade to MongoDB 4.0. We will examine how MongoDB 4.0 affects your organization ecosystem and what changes might be necessary prior to the upgrade. We will demonstrate the upgrade steps with a detailed rollback plan. Finally, we will cover some post-upgrade considerations that will allow you to release the power of MongoDB 4.0.

How are you doing integration tests with your datastore?
* Mocking is not an option since you want to test the actual system.
* There are some in-memory implementations, like H2 or HSQLDB for relational databases, but there are still subtle differences to your production system and not all datastores have in-memory cousins.
* Using the actual datastore in your tests is possible, but managing it, running tests in parallel,... is far from ideal.

So what is the solution? There are some very neat solutions based on containers, namely the Docker-Maven-Plugin and TestContainers. From your tests you can start a lightweight, throwaway instance of your datastore and this talk will walk you through how to do that.

This session will be interesting for everyone looking for the latest news about MySQL 8.0 Performance:
- MySQL 8.0 is GA now !
- but what about MySQL 8.0 Performance? ;-)
- the latest benchmark results obtained with MySQL 8.0 will be in the center of the talk
- because every benchmark workload for MySQL is a "problem to resolve"
- and each resolved problem is a potential gain in your production!
- many important internal design changes are coming with MySQL 8.0
- how to bring them in action most efficiently?
- what kind of trade-offs to expect, what is already good, and what is "not yet"?
- how well MySQL 8.0 is able to use the latest HW?
- could you really speed-up your IO by deploying your data on the latest flash storage?
- these and many other questions are answered during this talk + proven by benchmark results.

NOTE: since MySQL 8.0 we're following a "continuous release" model, so with every update there is some new improvement coming, the performance included ;-))

Percona XtraDB Cluster (a.k.a PXC) is multi-master high-availability clustering solution. Given the multi-master aspect, there are multi-guards to protect cluster from entering an inconsistent state. Most of these guards are configurable based on user environment but if they are not configured properly it could cause the cluster to stall, fail, error-out.

In this session, we would go over some of these failure scenarios like cluster entering non-primary due to network partitioning, cluster stall due to flow control, data inconsistency causing shutdown of node, common problem during initial catch up (a.k.a State Snapshot transfer (SST)), delay in purging of transaction, blocking DDL causing complete cluster to staff, misconfigured cluster, etc…

We would also discuss how to solve some of these problems or have to safely recover from these failures.

PostgreSQL is an advanced open source database that is completely community driven. Continuous development and performance improvements while maintaining a secondary focus on Oracle compatibility gave PostgreSQL a great market penetration. When a database server is deployed in production we often wish to achieve several 9's of availability. Is that even possible with PostgreSQL? What is the combination of tools that you could combine and implement to achieve High Availability (HA) and automatic failover in PostgreSQL? How can we avoid data loss during such failover's? We'll address these questions and then some more in this talk.

Kubernetes, and its most popular distribution OpenShift, receives a lot of interest as a container orchestration platform. However, databases remain a foreign entity, primarily because of their stateful nature.

In this presentation I discuss how to deploy Open Source databases (MySQL/Percona XtraDB Cluster and MongoDB) on Kubernetes/Openshift. For Percona XtraDB Cluster (PXC) we will be using MySQL Proxy to implement read/write splitting.

If you have never used Kubernetes and Openshift, I will do a quick introduction to these technologies. There will also be a demo where I will set up a PXC cluster with ProxySQL as well as MongoDB replicaset in Openshift Origin and will try to break it.

By the end of this webinar you will have a better understanding of:

* How to leverage Kubernetes/Openshift in your environments
* How to deploy opensource databases in Kubernetes/Openshift with StatefulSet.
* How to operate the databases in Kubernetes

PostgreSQL is one of the leading open-source databases. Out of the box, the default PostgreSQL configuration is not tuned for any particular workload. The default configuration is designed in such a way that PostgreSQL can run on any system with least resources. PostgreSQL does not give optimum performance on high permanence machine because it is not using the all available resource. PostgreSQL provides a system you can tune your database according to your workload and machine specification. Other than PostgreSQL we can also tune our Linux box so that database load can work optimally. Here we learn how to tune PostgreSQL and will see the results of that tuning, We will also touch some of the Linux kernel parameters tuning.

At Zalando we run PostgreSQL at scale: a few hundred database clusters in sizes from a few megabytes up to 10 terabytes of data. What is a bigger challenge than running a high-OLTP multi-terabyte PostgreSQL cluster? It is the migration of such a cluster from the bare-metal data center environment to AWS.

There were multiple problems to solve and questions to answer:
* Which instance type to choose: i3 with ephemeral volumes or m4/r4 + EBS volumes?
* Should we give Amazon Aurora a try?
* There is no direct connection from AWS to the data-center. How to build a replica on AWS and keep it in sync if VPN is not an option?
* The database is used by a few hundred employees for ad-hoc queries; ideally, they should retain access through the old connection url.
* How to backup such a huge DB on AWS?
* We should be able to switch back to the data-center if something goes wrong.

In this talk I am going to provide a detailed account of how we managed to successfully solve all these problems.

Apache Cassandra 4.0 has several enhancements. One of the biggest enhancements is switching from blocking network IO using JDK Sockets to Non-Blocking IO with Netty. As a result, Cassandra has seen gains in performance and efficiency. These gains translate into real-world costs and allow Cassandra to scale better. This presentation will take you on a tour of the improvements of Cassandra's network layer (old & new) and help quantify the gains in real-world terms.

Up to MySQL 5.5, replication was not crash safe: after a crash, it would fail with "duplicate key" or "row not found" error, or might generate silent data corruption. It looks like 5.6 is much better, right? The short answer is maybe: in the simplest case, it is possible to achieve replication crash safety but it is not the default setting. MySQL 5.7 is not much better, 8.0 has safer defaults but it is still easy to get things wrong.

Crash safety is impacted by replication positioning (File+Pos or GTID), type (single-threaded or MTS), MTS settings (Database or Logical Clock, and with or without slave preserve commit order), the sync-ing of relay logs, the presence of binary logs, log-slave-updates and their sync-ing. This is very complicated stuff and even the manual is confused about it.

In this talk, I will explain the impact of above and help you finding the path to crash safety nirvana. I will also give details about replication internals, so you might learn a thing or two.

In this presentation attendees will see the performance of a MySQL Server increase by automatic tuning using an open source GA (Genetic Algorithm) with surrounding smart bits. The full interface code will be made publicly available as open source on GitHub.

Genetic Algorithms - a kind of Artificial Intelligence - have been used for a long time, but only recently the interest towards database applications has spiked.

You will see the transactions per second increase and increase again as the server is being adjusted automatically.

You will walk away with a better understanding of Genetic Algorithms, it's application to automated database tuning, and how to start with (or continue) your own experiments in this area.

All new work, this setup has not been showcased anywhere before.

Troubleshooting the database-related problems turns out to be not a simple task even if you run your database on-premise. And performance debug can become a nightmare when you run it as a managed service in AWS/GCP/Azure, because you have no access to the underlying OS, and series of DB metrics gathered by your monitoring solution is the only subject you have to explore.

The talk will make an overview of a monitoring possibilities available for MySQL/PostgreSQL managed database in case of AWS, GCP, and Azure cloud providers. We will review what monitoring data can be gathered, speak about data granularity, and discuss ways to export these metrics to Prometheus for their simplified representation and wide/complex troubleshooting analysis of the whole instance.

The Elephant Shed is an Open Source PostgreSQL Appliance that bundles and integrates proven components, required for easy management of a PostgreSQL server.

It takes more than one piece of software to create a reliable and serviceable platform. There are different approaches to fill the gap, but usually Open Source offers all the bits and pieces needed. However, these need to be well integrated. Elephant Shed is such an integration of all the necessary tools for a high-performance PostgreSQL platform.

The wheel is not reinvented. Instead of new developments, established and reliable open source projects that fullfill the needs of the specific aspect are assembled into the Elephant Shed PostgreSQL appliance. These are integrated within a single user interface. Automated scripts in the background ensure that the interaction of all these tools runs smoothly.

This presentation reasons why Elephant Shed was created and shows the technical details and the advantages it brings.

Prometheus has become the go-to system for monitoring cloud-native infrastructures such as Kubernetes, with lots of integration points and options.

In this talk, we will look at all the relevant pieces for setting up Prometheus monitoring of your Kubernetes cluster - primarily from a user's perspective but also peeking under the hood to see how things work.

On the Prometheus side, we'll cover the different ways that service discovery and relabelling can be used, and how they make Prometheus so flexible.

On the Kubernetes side, we'll look at the alphabet soup of available metrics exporters (kube-state metrics, cAdvisor, node exporter, and friends).

Finally, we'll take a step back and consider how Prometheus' somewhat unique design and feature set fits into the broader landscape of monitoring systems, and how it is especially suited to cloud-native environments like Kubernetes.

MySQL 8 introduces a feature that is explained in a single document page, but that can help a lot if correctly used.
It is well hidden, in the optimization: optimizing of the MySQL server chapter.
I am talking of Resource Groups.
Resource groups permit assigning threads running within the server to particular groups so that threads execute according to the resources available to the group.
Group attributes enable control over its resources, to enable or restrict resource consumption by threads in the group. DBAs can modify these attributes as appropriate for different workloads.
This small simple feature can be a blast in case you have contention between different type of load on your database.
The simplest example is a combination of OLTP/OLAP or OLTP/ETL.
In this presentation, I will illustrate the feature and how it can be easily and successfully implement.
Also covering those contexts, like large enterprises, where code dynamic is not as agile as we would like to be.

As one of the world's most popular piece of server software and part of critical infrastructure, hosting vast amounts of databases, it is crucially important that it stays safe and operates without security issues. History has shown us we cannot trust any piece of software to be inherently secure, thus any project must have proper vulnerability disclosure and management procedures, be eager to collaborate with the security community and follow disclosure guidelines, as well as pro-actively look for security bugs in their own code base.

Lag in asynchronous replication is proportional to the gap in throughput between the master and slave. While a great deal of work has been done to make masters faster on multi-core machines, slaves have been left behind. Today, the master-slave throughput gap is essentially a parallelism gap. Parallel application of a serial log of transactions is not trivial.

In this work, our aim was to match the slave's throughput with the master's instead of just making it 'X' times faster. We use information already present in row based binary logs to extract fine-grained dependencies between row mutations which enables the slave to schedule transactions to multiple threads just like the master would have. We also explore how we can relax the transaction execution model on the slave to make them more lightweight and boost single threaded performance.

The market coined the term "enterprise grade" or "enterprise ready" to differentiate products and service offerings for licensed database software. For example: there may be a standard database software or an entry-level package that delivers the core functionality and basic features. Likewise, there may be an enterprise version, a more advanced package which goes beyond the essentials to include features and tools indispensable for running critical solutions in production. With such a differentiation found in commercial software, we may wonder whether a solution built on top of an open source database like PostgreSQL can satisfy all the enterprise requirements.

Both Galera and Group Replication provide clustering solution with virtual synchronous replication. The different replication technologies used by these two products ensure that data is replicated, consistent and safe and that several failure scenarios can be handled maintaining high availability. Although the database layer is highly available, applications rarely know the status of the various nodes in the cluster, therefore sending traffic to the wrong node(s) in a degraded system can lead to a high error rate.
ProxySQL has the ability to regularly check the status of the various nodes in the cluster, and determine which nodes are healthy and where to send traffic.
This session will present how to configure ProxySQL as a middle layer between the application and a clustering solution with either Galera or Group Replication, what algorithms are used to route traffic to the right node(s) and ensure that high availability is achieved even in case of degraded cluster conditions.

How do you exclude one table access from a database with too many tables? In previous versions of MariaDB and MySQL, you have to specifically grant access to all other tables individually. This does not scale, especially if tables are created and dropped frequently.

Reverse privileges solve this problem and many other use cases. With just one SQL statement you can ensure a user can never access a resource, regardless which roles or other privileges are granted to it.

Reverse privileges do not work in a vacuum, so we will start with a broad view of the full privilege system, before diving into the specifics of denying access to resources.

pg_chameleon is a lightweight replication system written in python. The tool can connect to the MySQL replication protocol and replicate the data changes in PostgreSQL.

Whether the user needs to set up a permanent replica between MySQL and PostgreSQL or perform an engine migration, pg_chameleon is the perfect tool for the job.

The talk will cover the history the current implementation and the future releases.

The audience will learn how to set up a replica from MySQL to PostgreSQL in a few easy steps. There will be also a coverage on the lessons learned during the tool's development cycle and a small demo.

Database performance affects organizational performance, and we tend to look for quick fixes when under stress. But how can we better understand our database workload and factors that may cause harm to it? What are the limitations in MongoDB that could potentially impact cluster performance?

In this talk, we will show you how to identify the factors that limit database performance. We will start with the free MongoDB Cloud monitoring tools. Then we will move on to log files and queries. To be able to achieve optimal use of hardware resources, we will take a look into kernel optimization and other crucial OS settings. Finally, we will look into how to examine performance of MongoDB replication.

Yoshinori Matsunobu - Facebook

At Facebook, we created MyRocks (RocksDB Storage Engine for MySQL) a few years ago. Since then, we have migrated from InnoDB to MyRocks in our top three largest database services, including Facebook Messenger. On the other hand, we still have many InnoDB instances, especially for general purpose use cases. At previous Percona Live conferences, I spoke about how we migrated from InnoDB to MyRocks. In this session, I am going to talk more about lessons learned after migration. Topics like what kinds of production issues we faced will be covered. I am also going to talk about how we migrated Facebook Messenger -- from HBase to MyRocks.

We store data with the intention to use it: search, retrieve, group, sort... To perform these actions effectively MySQL storage engines index data and communicate statistics with the Optimizer when it compiles a query execution plan. This approach works perfectly well unless your data distribution is not even.

Last year I worked on several tickets where data follow the same pattern: millions of popular products fit into a couple of categories and rest used the rest. We had a hard time to find a solution for retrieving goods fast. Workarounds for version 5.7 were offered. However new MySQL 8.0 feature: histograms, - would work better, cleaner and faster. This is how the idea of the talk was born.

I will discuss
- how index statistics physically stored
- which data exchanged with the Optimizer
- why it is not enough to make correct index choice

In the end, I will explain which issues resolve histograms and why using index statistics is insufficient for fast retrieving of not evenly distributed data.

PostgreSQL provides a way to communicate with external Data sources which can be another PostgreSQL instance or any other Database. The other database can be a Relational database like MySQL, Oracle or any NoSQL Database like MongoDB or Hadoop. PostgreSQL Implements ISO Standard call SQL-MED to achieve that capabilities. This Presentation will explain the advantage of this feature and the working of that feature with examples.

Calin Don - Presslabs, Flavius Mecea - Presslabs

The myth that containers aren't ready for databases still persists. We're not buying it.

We have built and open-sourced the MySQL operator for Kubernetes to solve this problem as a layer in the Presslabs stack for open WordPress hosting infrastructure.
We operate with lots of small to medium-sized DBs, in a DB-per-service model, as we call it. The workloads are mostly reads, so we need to efficiently scale that. The MySQL asynchronous replication model fits the bill very well, allowing to scale horizontally from one server (with the obvious availability pitfalls) to tens of nodes.
The operator is based on Percona Server for MySQL for its operational improvements —like utility user and backup locks—and relies on Orchestrator to do the automatic failovers.

We plan to integrate it with Percona Management & Monitoring. Community feedback on the operations it automates and to make sure that the data is safely stored is very welcome.

Nick Vyzas - ProxySQL

MySQL replication allows you to write on one writer server and easily scale out reads by redirecting reads to reader servers. But how do we guarantee read consistency with their last write? Galera replication can guarantee that, while MySQL Group Replication and standard MySQL async replication cannot.

If you are running MySQL Server or Percona Server, version 5.7 or newer, with GTID enabled, ProxySQL 2.0 is now able to ensure read consistently with the last write. ProxySQL is able to stream GTID information from all the reader servers, and in real-time is able to determine which reader server(s) is able to execute the SELECT statement producing a resultset that is read consistently with the last write (and GTID) executed by each client.

This presentation will show the technical details that allow you to build an architecture with thousands of ProxySQL instances and MySQL servers, and how GTID information is processed in real-time with limited bandwidth footprint.

Do you ever wonder why your MongoDB databases seem to be much slower than expected? Do you experience periodical hot spots and want to know the culprit(s)? Do you want to know which database operations are the most expensive and the ones most meaningful to improve?

In this talk you will quickly understand the limits of MongoDB's built-in database profiler, especially in sharded environments. I will present an open source tool we developed to solve these issues. We created a tool that collects, stores and helps to visually analyze slow MongoDB operations. By using the tool you will get a better picture of your MongoDB clusters without the need of a deeper MongoDB expertise. The tool runs database commands simultaneously against a multitude of databases or mongod's and with just a few clicks you can easily intervene and spot performance issues.

We present a kV database named "SharedRocks" which use d master-slave replication architecture for single write and multi-reads. It has high availability feature and easy to recovery from crashing. It's built on RocksDB which is the most popular key-value storage engine and PolarStore(PolarFS). The Alibaba's shared file storage. The shared file storage engine provides file persistence with three replicas and variety of new generation hardwares like RDMA, SPDK, etc. SharedRocks implements the master-slave replication between SharedRocks data nodes that are distribution architecture. SharedRocks' read only(slave) nodes are deployed very convenient. because of both of data and status are persistent on shared file storage. SharedRocks can access them anywhere..

So, you are a developer or sysadmin and showed some abilities in dealing with databases issues. And now, you have been elected to the role of DBA. And as you start managing the databases, you wonder…

* How do I tune them to make best use of the hardware?
* How do I optimize the Operating System?
* How do I best configure MySQL or MariaDB for a specific database workload?

If you're asking yourself the following questions when it comes to optimally running your MySQL or MariaDB databases, then this talk is for you!

We will discuss some of the settings that are most often tweaked and which can bring you significant improvement in the performance of your MySQL or MariaDB database. We will also cover some of the variables which are frequently modified even though they should not.

Performance tuning is not easy, especially if you're not an experienced DBA, but you can go a surprisingly long way with a few basic guidelines.

In this session, we will dive deep into HOT (Heap Only Tuple) update optimization. Utilizing this optimization can result in improved writes rates, less index bloat and reduced vacuum effort but to enable PostgreSQL to use this optimization may require changing your application design and database settings. We will examine how the number of indexes, frequency of updates, fill factor and vacuum settings can influence when HOT will be utilized and what benefits you may be able to gain.
