Rene Cannao - ProxySQL

The inability to control the traffic sent to MySQL is one of the worse nightmares for a DBA. Scaling out and high availability are only buzz words if the application doesn't support such architectures. ProxySQL is able to create an abstraction layer between the application and the database: controlling traffic at this layer hides the complexity of the database infrastructure from the application, allowing both HA and scale out. The same layer is able to protect the database infrastructure from abusive traffic, acting as a firewall and cache, and rewriting queries.

Marco Tusa - Percona

ProxySQL is a very powerful platform that allows us to manipulate and manage our connections and queries in a simple but effective way.

Historically MySQL falls short in sharding capabilities. This significant area often caused developers to implement sharding at the application level, or DBAs/SAs to move on to another solution. ProxySQL has an elegant and simple solution that allows us to implement MySQL sharding capabilities without the need to perform significant (or any) changes in the code.

This brief presentation will illustrate how to successfully configure and use ProxySQL to perform sharding. We will cover very simple approaches based on connection user/IP/port, to complicated ones that see the need to read values inside queries.

Please note this presentation requires at least some basic ProxySQL knowledge.

Docker is becoming more mainstream and adopted by users as a method to package and deploy self-sufficient applications in primarily stateless Linux containers. It's a great toolset on top of OS-level virtualization (LXC, a.k.a containers) and plays well in the world of micro services.

However, Docker containers are transient by default. If a container is destroyed, all data created is also lost. For a stateful service like a database, this is a major headache to say the least.

There are a number ways to provide persistent storage in Docker containers. In this presentation, we will talk about how to setup a persistence data service with Docker that can be torn down and brought up across hosts and containers.

We will touch upon orchestration tools, shared volumes, data-only-containers, security and configuration management, multi-host networking, service discovery and implications on monitoring when we move from host-centric to role-centric services with shorter life cycles.

Elasticsearch is a distributed, RESTful search and analytics engine built on top of Apache Lucene. After the initial release in 2010 it has become the most widely used full-text search engine, but it is not stopping there.

The revolution happened and now it is time for evolution. We dive into the following questions:
How did numbers and metrics become first class data in a search engine?
How do shard allocations (which were hard to debug even for us) work and how can you find out what is going wrong with them?
How can you search efficiently across clusters and why did it take two implementations to get this right?
What are current problems and their solution around resiliency and strictness?
Why are types finally disappearing and how are we avoid upgrade pains as much as possible?
How can upgrades be improved so that nobody is stuck on old or even ancient versions?

Attendees learn both about new and upcoming features as well as the motivation and engineering challenges behi

Sveta Smirnova - Percona

Replication is one of the features that made MySQL a popular RDBMS. It is easy to setup, and by default it allows read-write access on both the master and slave. It is also easily creates complicated deployments, such as circular replication.

By default, MySQL Replication is asymmetrical, but it has semi-sync replication plugin. Since version 5.7 it supports multi-master slaves. All these features implement a quick start, but there is also a huge risk of making the wrong decision.

In this session, I will demonstrate why one or another replication solution can fail with data loss or perform slowly. I will show methods that will help you to diagnose and resolve these issues.

This session uses built-in, then command-line tools, because knowledge of how they work is essential for effective troubleshooting.

Michael Demmer - Slack

Slack is embarking on a major migration of the mysql infrastructure at the core of our service to use Vitess' flexible sharding and management instead of our simple application-based shard routing and manual administration. This effort is driven by the need for an architecture that scales to meet the growing demands of our largest customers and features under the pressure to maintain a stable and performant service that executes billions of MySQL transactions per hour. This talk will present the driving motivations behind the change, why Vitess won out as the best option, and how we went about laying the groundwork for the switch. Finally, we will discuss some challenges and surprises (both good and bad) found during our initial migration efforts, and suggest some ways in which the Vitess ecosystem can improve that will aid future migration efforts.

Prometheus is an open source time series database and monitoring system. It is very simple to use and has no external dependencies. It has a powerful query language to retrieve and evaluate metrics.

However, Prometheus storage engine is designed for keeping mainly the short-term data. This gap can be filled in by InfluxDB time-series database having it to store the long-term data and perform downsampling.

Learn the pros and cons of those time-series databases and how to hook up Prometheus with InfluxDB for the long-term storage of your metrics, maintain retention and get trends in system performance with Grafana.

Kimberly Wilkins - ObjectRocket

MongoDB and Elasticsearch are both NoSQL "databases", or more correctly NoSQL data stores that are often compared and contrasted on a head-to-head basis.

But if comparing that way, one could easily miss out on the opportunity to use both together as individual and independent data stores that serve specific purposes to deliver the best overall solution for your application flow and performance needs.

In this talk, Kimberly will discuss the overall aspects of each technology, best use cases, the strengths and weaknesses of each, scaling, and provide examples for each with details for the underlying technology with architectural information and basic functioning of these two data stores.

Join her as she will offer opinions on the best times to use separately as independent data stores plus the chance to combine the two to get the absolute performance often needed by today's applications and the large amounts of data required.

Krzysztof Ksiazek - Severalnines AB

Load balancing MySQL connections and queries using HAProxy has been popular in the past years. Recently however, we have seen the arrival of MaxScale, MySQL Router, ProxySQL and now also Nginx as a reverse proxy.

For which use cases do you use them and how well do they integrate in your environment? This session aims to give a solid grounding in load balancer technologies for MySQL and MariaDB.

We will review the main open-source options available: from application connectors (php-mysqlnd, jdbc), TCP reverse proxies (HAproxy, Keepalived, Nginx) and SQL-aware load balancers (MaxScale, ProxySQL, MySQL Router).

We will also look into the best practices for backend health checks to ensure load balanced connections are routed to the correct nodes in several MySQL clustering topologies. You'll gain a good understanding of how the different options compare, and enough knowledge to decide which ones to explore further.

The topic of this presentation is how to use ElasticSearch (ES) in order to speedup otherwise slow MySQL analytic queries. For this, we will look at an actual business case for a ride-sharing application, with the actual trip data stored in MySQL.

First, we will examine the ES requirements and explain how to import this data in ES and sync both databases.

Some specifics of ElasticSearch will be discussed, notably the Query DSL as well as the differences with MySQL and how to convert SQL queries to the ElasticSearch DSL.

Then, we will show how to design analytic queries in ES using aggregation and geolocalization, giving some real world examples (e.g. average earning per driver with pickups in the brooklyn area) and performance comparisons with the equivalent queries in MySQL.

Finally, we will discuss how to scale this implementation and make it highly available using ES clustering and sharding features.

You have been asked to administer a Cassandra installation. In this talk, I will take you through basic Cassandra operations from the point of view of a MySQL DBA.

In the beginning, I was simply looking for "where is the equivalent of a .my.cnf?". Over time, that expanded to "how can I be sure this is healthy?", "Why are the users complaining about timeouts connecting?", and "How do I make this cluster replicate into another datacenter?". I will cover all of this and more.

Hopefully, my frustrations will save you some time and pain.

Dana Van Aken - Carnegie Mellon University

In the last two decades, both researchers and vendors have built advisory tools to assist database administrators (DBAs) in various aspects of system tuning and physical design. But these tools are incomplete because they still require humans to make the final decisions about any changes to the database and are reactionary measures that fix problems after they occur. What is needed is a truly "self-driving" database management system (DBMS) that is able to optimize the system for the current workload and predict future workload trends so that the system can prepare itself accordingly. It enables new optimizations that are not possible today because the complexity of managing these systems has surpassed the abilities of human experts. In this talk, I present Peloton, the first self-driving DBMS that we are building at CMU. Peloton's autonomic capabilities are now possible due to advancements in deep learning, as well as improvements in hardware and adaptive database architectures.

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.

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.

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.

We've migrated our platform (Kinja) from a datacenter-based approach to AWS, including migration of standalone MySQL hosts to RDS/Aurora.

I'd like to talk about our findings, what kind of problems we were hitting during this transition, giving you a hands-on experience about how you should change your thinking when you decide to move into a managed database service because it's a kind of different way compared to what you used to have.

I'd like to show you our best practices, I'd like to show some characteristics of Aurora, I'd like to show you a few of our utilties that we had to create to make daily operations possible.

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 Nordstrom - 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

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.

ClickHouse is an open source DBMS for high-performance analytics, originally developed at Yandex for the needs of Yandex.Metrica web analytics system. It is capable of storing petabytes of data and processing billions of rows per second per server, all while ingesting new data in real-time.

I will talk about architectural decisions we made with ClickHouse, their consequences from the point of view of an application developer and how to determine if ClickHouse is a good fit for your use case.

I will cover the following topics:
* Overview of storage engine and query execution engine.
* Data distribution and distributed query processing.
* Replication and where it sits on the consistency-availability spectrum.

Everyone already knows the Jsonb data type: one of PostgreSQL's most attractive features that allows efficient work with semi-structured data without sacrificing strong consistency and ability to use all the power of proven relational technology. But what exactly is inside Jsonb? Are there any caveats, and how can you accidentally bring down performance?

We will discuss all these questions together with advantages and disadvantages of using Jsonb in different situations in comparison with other solutions and existing standards. I'll show some important best practices about how to write compact queries to work with Jsonb, and avoid common mistakes/performance problems.

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.

Bernd Erk - Icinga

Icinga is a popular open source successor of Nagios that checks hosts and services, and notifies you of their statuses. But covering availability is not enough for a comprehensive database monitoring. On top of that, you need metrics for performance and growth to deal with your scaling needs. 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.
