MC Brown - Continuent

You may know Continuent Tungsten for our highly advanced MySQL replication tool or for our state-of-the-art MySQL clustering solution, Tungsten Clustering. Our solutions are used by leading SaaS vendors, e-commerce, financial services and telco customers. But there are more, many more, Tungsten deployments out there. Tungsten Replicator is also an Oracle replication solution, the "Oracle GoldenGate without the price tag”. Tungsten Replicator can also be used for real-time data loading into analytics, from MySQL and Oracle into Cassandra, Elasticsearch, Kafka, Redshift and Vertica. And there could be more... How about Tungsten Backup? Using the power of the Tungsten Transaction History Log (THL) , we may create the ultimate continuous backup solution with flexible point-in-time recovery. Would you be interested, especially for free? What about the ultimate proxy, a stand-alone Tungsten Connector? To support our Clustering solution, Continuent has developed one of the most advanced proxies available. Could it be time to unleash our Connector for public use?

Steve Shaw - Intel

When Intel launched the Xeon Scalable Processors in July 2017 the database benchmark used was HammerDB. HammerDB is an open source graphical benchmarking tool that enables the comparison between both open source and commercial databases on multiple platforms for OLTP and Query based workloads.
This presentation takes a real-world example of comparing MariaDB with a commercial database on Linux on Intel to show how to understand the benchmarks used and how to tune, configure and present findings on both performance and cost in a clear and concise way to evaluate the move to an open source database platform.
Based on the findings this session will share key learnings on current optimal platforms and storage technologies for database as well as the Intel focus on applying technologies to open source database acceleration such as FPGA and SSD and non-volatile memory.
Insights and previews will also be given into ongoing HammerDB development.

At the Wikimedia Foundation (host of Wikipedia and many other open collaborative projects) we work on a limited budget, donated by our many generous donors. As many other companies that are not Facebook- or Google-sized, we have to do more with less both in terms of budget and our small number of Ops in order to serve the over 400 thousand requests per second and the 1200 million monthly users. We made several mistakes (and a few successes) along the road regarding architecture and hardware decisions, especially for the database-distributed components, storage model, hardware chosen, server size, technology adoption, etc. Now we want to share those with you.

Rohit Kumar - Pythian, Martin Arrieta - Pythian, Kedar Vaijanapurkar - Pythian

As service providers, one of our responsibilities is helping clients understand what causes contributed to a production downtime incident, and how to avoid (as much as possible) them from happening again. We do this with Incident Reports, and one common recommendation we make is to have a historical monitoring system in place. All our clients have point-in-time monitoring solutions in place, solutions that can alert them when a system is down or behaving in unacceptable ways. But historical monitoring is still not common, and we believe a lot of companies can benefit from deploying one of them.

In most cases, we have recommended Percona Monitoring and Management (PMM), as a good and Open Source solution for this problem. In this session, we will talk about the reasons why we recommend PMM as a way to prevent incidents, and also to investigate their possible causes when one has happpened.

Alexander Zaitsev - LifeStreet / Altinity

At LifeStreet we needed to scale our real time ad analytics platform to multiple petabytes. We evaluated and used a number of Open Source and Commercial Solutions, but they were not efficient enough or too expensive. When Yandex has released ClickHouse to Open Source we quickly realized its potential, and started our implementation project. It was a long way but it finally worked out great.

In this presentation I will talk about our experiences from application developer's viewpoint - what worked well and not so well, what challenges we had to overcome as well as share share the best practices for building large scale platform based on ClickHouse.

Today, the world of IOT is still in a primordial stage: several vendors offer ?platforms? hoping to cover all the aspects of IOT projects in an attempt to simplify the flow and management of IOT data.

FogLAMP is the effort of organizations active in IOT, IIOT (Industrial Internet of Things) and Fog Computing to provide a fully open source stack operating from the Edge and integrated with other Cloud and Enterprise solutions. FogLAMP?s main objective is to simplify the management of IOT data, whether this data is simply stored and forwarded, or consumed and analyzed at the Edge.

We will talk about what is FogLAMP and how it works. We will explore the pluggable architecture and how the modularity of the product allows developers and architects to build IOT projects. We will also see FogLAMP in action in a demo with sensor data collected from the Edge, analyzed locally and pushed to OSIsoft PI System, used to collect, analyze, visualize time-series data.

Ruairí Newman - Severalnines AB

In any busy operations environment, there are countless tasks to perform - some monthly, or weekly, some daily or more frequently, and some on an ad-hoc basis. And automation is key to performing fast, efficient and consistently repeatable software deployments and recovery.

There are many generic tools available, both commercial and open source, to aid with the automation of operational tasks. Some of these tools are even deployed in the database world. However, there are a small number of specialist domain-specific automation tools available also, and we are going to compare two of these products: MongoDB?s own Ops Manager, and ClusterControl from Severalnines.

We will cover:

* Installation and maintenance
* Complexity of architecture
* Options for redundancy
* Comparative functionality
* Monitoring, Dashboard, Alerting
* Backing up and restoring
* Automated deployment of advanced configurations
* Upgrading existing deployments

Participants should take away a clear understanding of the differences between these tools, and how they help automate and manage MongoDB operations.

Anyone looking for a high availability master-slave management solution for MySQL may come across ProxySQL and Orchestrator. This combination of products solves many problems, but still requires some manual labour when the configuration changes, when there is a network split and other scenarios. In this talk I will discuss the standard architecture, the solutions it provides and what it's missing. I will then share an automation solution developed at Wix, that solves those problems using Consul, to combine everything together.

Matthew Lang - Continuent

The MySQL marketplace has quite a few High-Availability (HA) solutions such as Continuent Tungsten, Galera/XtraDB Cluster, various MySQL script/patch solutions, and RDS with multi-zone HA. Providing seamless, automatic failover with zero down-time maintenance in one data center can be challenging, but extending that same functionality across multiple sites in different continents truly makes that a difficult goal to achieve. Continuent has perfected various cluster solutions over the years and we have many customers running them in production, with more currently converting from Galera or RDS to our solutions.

Instead of using ETL Tools, which consume tons of memory on their own system, you will learn how to do ETL jobs directly in and with a database: PostgreSQL.

PostgreSQL Management of External Data (SQL/MED) is also known as Foreign Data Wrapper (FDW). With FDW, there is nearly no limit of external data, that you could use directly inside a PostgreSQL database.

This talk will show you how to use them with examples accessing several data sources.

Erik Nordström - Timescale

When storing time-series data, many developers start with some well-trusted system like Postgres, but as their data hits a certain scale, give up its query power and ecosystem by migrating to a NoSQL or other "modern" time-series architecture.

In this talk, I describe why this trade-off is unnecessary, and how we've built TimescaleDB, an efficient, scalable time-series database engineered up from Postgres. The nature of time-series workloads--appending data about recent events--presents different demands than transactional (OLTP) workloads. We've architected our time-series database to take advantage of and embrace these differences.

TimescaleDB improves insert rates by 15X over Postgres, even on a single node. By right-sizing chunks, it avoids the "performance cliff" Postgres experiences once reaching table sizes of 50+ million of rows, while offering compelling complex query performance improvements. TimescaleDB is packaged as a Postgres extension, released under the Apache

MySQL security is an interesting subject. In this session we'll show how to use Vault (https://www.vaultproject.io) to create a secrets store we can authenticate against using GitHub. On the other side, we'll demonstrate how we can use Vault to dynamically grant and revoke rights on a running MySQL Server. The end result allows us to not have to have a real MySQL user, but instead we first authenticate against Vault and then ask Vault for temporary access credentials to the MySQL instance of choice.

Planning to offer MySQL, but hoping to offer high availability or horizontal scaling capacity? Galera seems like the perfect fit! And it can be, so long as you and your developers are aware of several important hazards. Galera's documentation hints at these, but understanding the implications of their warnings can be tricky. This presentation will take you through the street signs you may encounter on the road to Galera, and how to interpret them quickly. This guide will help you choose the best path for you and your users.

The open source Platform as a Service project, Cloud Foundry, gives developers self-service access to relational databases. The open source project, cf-mysql, allows CF Operators reliable, automated access to slices of a MySQL Galera cluster. Over the years, we've experienced many different deployments under many different conditions. We'll share what we've learned, what worked, and what we'd do differently based on our use cases.

This presentation will highlight the new support for SQL window functions in MySQL 8.0: showing how they can be used to simplify and speed up analytical queries. The talk will first give a gentle introduction to basic concepts like partitions, frames and peers, explaining the differences between physical and logical frames. Then we move on to the two kinds of window functions and show their usage: SQL aggregates like COUNT and SUM used as window functions, as well as the dedicated window functions like ROW_NUMBER, NTILE, LEAD and more.

We will also cover some implementation aspects, particularly as they pertain to performance.

MySQL offers all the standard non-aggregate window functions, as well as most of the existing MySQL aggregate functions used as window functions. Window functions have the potential to greatly speed up many kinds of queries, and should be in the repertoire of all SQL developers.

As a support engineer, everyday we get dozens of pt-stalk captures from our customers containing samples of iostat, vmstat, top, ps, SHOW ENGINE INNODB STATUS, SHOW PROCESSLIST and a multitude of other diagnostics outputs.

These are the tools of the trade for performance and troubleshooting, and we must learn to digest these outputs in an effective and systematic way to allow us to provide high quality service to a large volume of customers, and that is the knowledge we want to share through this presentation.

We will learn to setup, capture data, write plugins to trigger collection and to capture custom data, look at our systematic approach and learn what data to read first and how to unwind the tangled threads of pt-stalk.

By the end of this presentation you will have expert knowledge on how to capture diagnostic metrics at the right time and will have a generic approach to digest the captured data, allowing you to work on a large number of problems common to MySQL setups.

Alexander Kukushkin - Zalando SE

At a blistering pace and for a variety of reasons, companies are migrating their on-premise database infrastructures to cloud-based solutions?to save costs on hardware, tame the impact of disaster recovery or even to improve security. Zalando is not an exception and more than two years ago we migrated our first production services to AWS.

In addition to the fully managed database services like RDS and Aurora, Amazon offers a wide spectra of EC2 instances with different performance and price. Without a lot of experience in running cloud databases it's not easy to make a right choice and as a result you will either have a pure database performance or you will overpay for over-provisioned resources.

In this talk I will explain why we decided to run most of our databases on EC2 Instances instead of RDS, how we chose EC2 Instance types and EBS Volume sizes, which AWS CloudWatch metrics MUST be monitored (and why), what problems we hit and how to avoid them.

The database team at GitHub is tasked with keeping the data available and with maintaining its integrity. Our infrastructure automates away much of our operation, but automation requires trust, and trust is gained by testing. This session highlights three examples of infrastructure testing automation that helps us sleep better at night:

- Backups: scheduling backups; making backup data accessible to our engineers; auto-restores and backup validation. What metrics and alerts we have in place.
- Failovers: how we continuously test our failover mechanism, orchestrator. How we setup a failover scenario, what defines a successful failover, how we automate away the cleanup. What we do in production.
- Schema migrations: how we ensure that gh-ost, our schema migration tool, which keeps rewriting our (and your!) data, does the right thing. How we test new branches in production without putting production data at risk.

Dana Van Aken - Carnegie Mellon University

Database management systems (DBMSs) are the most important component of any data-intensive application. They can handle large amounts of data and complex workloads. But they're difficult to manage because they have hundreds of configuration "knobs" that control factors such as the amount of memory to use for caches and how often to write data to storage. Organizations often hire experts to help with tuning activities, but experts are prohibitively expensive for many.

In this talk, I will present OtterTune, a new tool that can automatically find good settings for a DBMS?s configuration knobs. OtterTune differs from other DBMS configuration tools because it leverages knowledge gained from tuning previous DBMS deployments to tune new ones. Our evaluation shows that OtterTune recommends configurations that are as good as or better than ones generated by existing tools or a human expert.

"It's just a log, right?" How hard can it be, how can you possibly mess this up?

Wrong. Logs can impact your reliability, performance and quality of sleep in a million ways small and large. In this session we'll cover some of the lessons every engineer should know (and often learns the hard way), such as why good logging solutions are so expensive, why treating your logs as strings can be costly and dangerous, how logs can impact code efficiency and add/fix/change race conditions in your code. And what's the difference between a log line and an event, anyway?

We'll talk about how to craft a good, helpful log line or event and how to spot a bad one. We'll also talk about trends in debugging for complex systems, like the drive for structured logs/events and what comes next.

Adding conditional behaviours and configuration in Icinga is not just intuitive, but also intelligently adaptive at runtime. This makes it easy to deal with a bunch of different database flavours at once.

If we are talking about any MySQLish, PostgreSQL, MongoDB, or whatever open source database, Icinga is able to give you all the needed information. The talk will give you a detailed introduction into Icinga's abilities and shows practical guidelines for a successful database monitoring in a live demo.

David Murphy - Percona

Unlike MySQL (and the MySQL manual), there are hidden variables in MongoDB that no one really documents. But they can control things such as how data sets are returned, to connection pool size/ timeouts, to even if intersections should be allowed.

In this talk, we will show you examples of these knobs, how to find them on GitHub, what they are for and when to use them.

Beyond that, we will also talk about some very unknown WiredTiger and MongoRocks internal engine settings that are useful for when your database grows and needs a bit of tweaking to save the day.

MySQL replication has been changing considerably over the years to meet the demands of highly volatile and very dynamic deployments of MySQL technology. The fact is that the MySQL that powered the LAMP stack is now powering the infrastructure of many of the popular cloud solutions out there. A common factor across them is replication, which has been often used for read scale-out. In fact, it has also deployed as the foundation to provision high availability and address disaster recovery when deployed across wide-area networks. Elasticity and redundancy are thus key properties in old as in new deployments.

The new replication features in MySQL 8 continue to match the requirements set in order to address web scale scenarios. All of this without compromising on features that are also important when deploying MySQL on premise or local clouds.

Come and learn about the new replication features in MySQL 8 that you will use to grow your business on top
of MySQL.

sysbench is a benchmark tool that is quite ubiquitous in the MySQL community. It is used by both beginners and huge corporations alike as a quick way to evaluate general system performance, a universal measuring tool to compare configuration or code changes, server releases or server flavors, or as a part of QA process. This session will present new features provided by recent releases and explain how they can be used to create complex benchmark scenarios and collect performance metrics with a simple Lua API.

We will also run a live demo of some of the new sysbench features.

Tom Arnfeld - Cloudflare

Cloudflare operates multiple DNS services that handle over 100 billion queries per day for over 6 million internet properties. We collect and aggregate logs for these queries for customer analytics, DDoS attack analysis and ad-hoc debugging. Due to the scale at which we operate, we've had to be creative in our implementation. In this talk, I'll go into more detail on the architecture we use for log ingestion and insertion into a ClickHouse cluster, as well as how we aggregate the data over time for longevity. I'll also touch on the tools we use downstream of ClickHouse to visualize and analyze the data ad-hoc.
