Peter Zaitsev - Percona

As open source database adoption continues to grow in enterprise organizations, the expectations and definitions of what constitutes success continue to change. In today's environment, it's no longer a question of which database to use, but which databases do you need, what platforms will you deploy them on, and how do you get them to work together. A single technology for everything is no longer an option; welcome to the polyglot world.

At Percona, we see a lot of compelling open source projects and trends that we think the community will find interesting. Following Peter's keynote, we will have a round of lightning talks from projects that we think are stellar and deserve to be highlighted.

Automatization of Postgres Administration
Cloud services like Amazon RDS or Google Cloud SQL help to automate half of DBA tasks: launch database instances, provision replicas, create backups. But the other, very important part is almost not automated now: database tuning and query optimization.

High Performance, Scalable, and Available MySQL Clustering System for the Cloud
Vitess is now used in production at multiple companies. Vitess shines in this area by providing query logs, transaction logs, information URLs, and status variables that can feed into a monitoring system like Prometheus.

Ghostferry: the Swiss Army Knife of Live Data Migrations with Minimum Downtime
Inspired by gh-ost, our tool is named Ghostferry and allows application developers at Shopify to migrate data without assistance from DBAs. We plan to open source Ghostferry at the conference so that anyone can migrate their own data with minimal hassle and downtime.

What is a Self-Driving Database Management System?
People are touting the rise of ""self-driving"" database management systems (DBMSs). But nobody has clearly defined what it means for a DBMS to be self-driving. Thus, in this keynote, Andy provides the history of autonomous databases and what is needed to make a true self-driving DBMS.

Andy Pavlo - Carnegie Mellon University

In the last 20 years, researchers and vendors have built advisory tools to assist DBAs in tuning and physical design. Most of this previous work is incomplete because they require humans to make the final decisions about any database changes and are reactionary measures that fix problems after they occur. What is needed for a "self-driving" DBMS are components that are designed for autonomous operation. This will enable new optimizations that are not possible today because the complexity of managing these systems has surpassed the abilities of humans.

In this talk, I present the core principles of an autonomous DBMS based on reinforcement learning. These are necessary to support ample data collection, fast state changes, and accurate reward observations. I will discuss techniques on how to build a new autonomous DBMS or retrofit an existing one. Our work is based on our experiences at CMU from developing an automatic tuning service (OtterTune) and our self-driving DBMS (Peloton).

Igorcho Donchovski - Pythian

Redundancy and high availability are the basis for all production deployments. Database systems with large data sets or high throughput applications can challenge the capacity of a single server like CPU for high query rates or RAM for large working sets. Adding more CPU and RAM for vertical scaling is limited. Systems need horizontal scaling by distributing data across multiple servers.

MongoDB supports horizontal scaling through sharding. Each shard consists of a replica set that provides redundancy and high availability. In this session we will talk about:

-How MongoDB HA works
-Replica sets components/deployment typologies
-Cluster components - mongos, config servers and shards/replica set
-Shard keys and chunks
-Hashed vs. range based sharding
-Reads vs. writes on sharded cluster

Charly Batista - Percona

The world is becoming increasingly complex for professionals working with data. The amount and diversity of data are on a level never before seen, and we often have to use different tools to store the increasing amount of data, for instance, MySQL and PostgreSQL.

It brings us another problem: how to make this ecosystem work properly? Is it possible to make them talk to each other? Is it possible to replicate from MySQL to PostgreSQL or vice-versa?

This presentation aims to do that, make MySQL talk to PostgreSQL and make them work together in a heterogeneous setup. We will see different tools and techniques like PostgreSQL Logical Decoding, SymmetricDS, pg_chameleon, Tungsten Replicator and in the end, we will have a heterogeneous setup with MySQL and PostgreSQL replicating from each other.

Gabriel Ciciliani - Pythian

DC/OS (Datacenter Operating System) is a novel solution to simply and efficiently run services and applications across on-premises, cloud or hybrid environments. Even though you can run any type of applications, DC/OS is an excellent fit for container based architectures.

Deploying a MySQL instance on DC/OS requires just a few clicks, but once the service is running, you may have a few questions, such as:

-"What" is actually running?
-How is data persistence is handled?
-How can I enable HA for my databases

The goal of this session is to help answer these questions and share some of the thought processes and lessons learned from a real-world implementation, provide the background of how DC/OS operates, and identify key items that need to be considered when deploying database services.

Jonathan Hyman - Braze Inc.

Braze is a lifecycle engagement platform used by consumer brand to deliver great customer experiences to over 1 billion monthly active users. In this talk, co-founder and CTO Jon Hyman will go over multiple production use cases Braze uses for buffering data to Redis for efficient real-time processing.

Braze processes more than a third of a trillion pieces of data each month when generating time series analytics for its customers. Jon will describe how each of these events gets buffered to Redis hashes, and some to Redis sets, before ultimately flushed to Braze's analytics database hundreds of thousands of times per minute. This talk will also discuss how Redis sets are the cornerstore of Canvas, Braze's user journey orchestration product used by brands such as OKCupid, Postmates, and Microsoft.

Lastly, Jon will cover how Braze has written its own application-based sharding for Redis in order to support the millions of operations per second that Braze needs to handle its daily volume.

Baron Schwartz - VividCortex

The interaction between applications and the database is one of the most intricate and important in the systems we build. This boundary region is special and complex for a number of reasons. It's the surface that separates stateful from stateless, off-the-shelf from custom, and battle-tested atoms from fast-changing molecules. But more than that, it's not crisply defined. There's no bright line that divides these worlds. Instead, there's a zone where each region is partially enmeshed. Consider schema and indexing design, for example, which is a combination of predefined and user-defined; the query language and its interplay with the planner is another. This is a zone of complexity and richness, where lots of gnarly things sprout, but also where there's a lot of opportunity to learn, so you can design and improve applications better. Baron will share lessons learned from his career of observing how applications and databases interact. You'll leave with insights that will help you see new ways to build better.

Rodrigo Medeiros - DataCore

Many administrators responsible for databases confront two clashing phenomena:

· Data is coming at increasingly higher rates (from an expanding number of sources)
· The time required to process transactions and analyze data is rapidly shrinking

The most common approaches to address these issues and speed up databases are to deploy new hardware and refactor code. At times, however, these approaches are not viable - particularly in the short term - due to implementation risks, cost, and timelines.

In this session, you will learn:

· How parallelism in the I/O layer impacts performance, particularly in database servers
· How interrupt-based I/O limits throughput in systems with high core count
· The connection between I/O waits and CPU context switches
· The impact of parallelizing I/O on solving these problems
· Cloud-based VMs, storage cost, and database performance
· A software-based alternative to mitigating I/O problems

Designing highly available database systems isn't a new topic. On the contrary, with so many options available to architects now, choosing the best fit isn't always trivial. This talk will walk through various options including Standard Multi A/Z MySQL RDS, Aurora for RDS, and Percona XtraDB Cluster in EC2. Comparison points will cover failover processes, accompanying software (primarily ProxySQL), and general use cases.

This is not meant to be a deep dive into any particular design, but rather assist in choosing the proper architecture for a given use case.

Dimitri KRAVTCHUK - MySQL/Oracle

This session will be interesting to everyone looking for the latest news about MySQL 8.0 performance:

- MySQL 8.0 is more and more close to GA now
- But what about MySQL 8.0 performance ? ;-)

The latest benchmark results obtained with MySQL 8.0 will be 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 is MySQL 8.0 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, plus proven by benchmark results.

Bill Karwin - Square

The JSON data type and functions that support it comprise one of the most interesting features introduced in MySQL 5.7 for application developers. But no feature is a "Golden Hammer." We need to apply a little expertise to get the best result, and avoid misusing it. I'll show practical examples that work well with JSON, and other scenarios where conventional columns perform better.

Questions addressed in this presentation:
- How much space does JSON data use, compared to conventional data?
- What is the performance of querying JSON vs. conventional data?
- How do I create indexes for JSON data?
- What kind of data is best to store in JSON?
- How do I get the best of both worlds?

By now you surely know that MongoDB 3.6 Community became generally available on Dec 5, 2017. Of course, this is great news: it has some big ticket items that we are all excited about! But we need to talk about general thoughts on this release good an

It is always a good idea for your internal teams to study and consider new versions. This is crucial for understanding if and when you should start using it. After deciding to use it, there is the question of if you want your developers using the new features (or are they not suitably implemented yet to be used)?

So what is in MongoDB 3.6 Community?

- Sessions
- Change streams
- Retryable writes
- Security improvement
- Major love for arrays in aggregation
- A better balancer
- JSON Schema validation
- Better time management
- Compass is community
- Major WiredTiger internal overhaul

As you can see, this is an extensive list. But there are 1400+ implemented Jira tickets just on the server (not even in the WiredTigers project).

This is a big so come hungry!

For the cloud environment, we hope MySQL cluster can do the failover and choose the new master node by the instance-self automatically, without third-party middleware. So we built the Raft protocol inside MySQL.
In MySQL-Raft version, every cluster usually has three nodes, one master and two slaves, but we can support more nodes. When master node is down, the cluster can choose the new master by Raft Protocol, and use Flashback to rollback the committed transactions if needed, to make sure all of the nodes are the same.

In this session, we will cover a number of the way that you can tune PostgreSQL to better handle high write workloads. We will cover both application and database tuning methods as each type can have substantial benefits but can also interact in unexpected ways when you are operating at scale.

On the application side, we will look at write batching, use of GUID's, general index structure, the cost of additional indexes and impact of working set size. For the database, we will see how wal compression, auto vacuum and checkpoint settings, as well as a number of other configuration parameters, can greatly affect the write performance of your database and application.

Matvey Arye - Timescale

The earliest relational databases were monolithic on-premise systems that were powerful and full-featured. Fast forward to the Internet and NoSQL: BigTable, DynamoDB and Cassandra. These distributed systems were built to scale out for ballooning user bases and operations. As more and more companies vied to be the next Google, Amazon, or Facebook, they too "required" horizontal scalability.

But in a real way, NoSQL and even NewSQL have forgotten single node performance where scaling out isn't an option. And single node performance is important because it allows you to do more with much less. With a smaller footprint and simpler stack, overhead decreases and your application can still scale.

In this talk, we describe TimescaleDB's methods for single node performance. The nature of time-series workloads and how data is partitioned allows users to elastically scale up even on single machines, which provides operational ease and architectural simplicity, especially in cloud environments.

Frédéric Descamps - Oracle, René Cannaò - 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 consistent 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.

In this session, we will discuss our fully automated failover solution running in containers on Kubernetes. Using Orchestrator for MySQL failovers, ProxySQL to route queries and a Zookeeper-backed application we wrote called Taiji for service discovery, database failures and topology changes are handled without any human intervention. This system is tolerant to network partitions and connectivity issues, node failures, and even full region outages.

After adding additional functionality to Orchestrator, we have it deployed with the raft consensus protocol and automatic failovers enabled. ProxySQL is deployed alongside a Taiji container that watches for changes in Zookeeper. All topology changes are automatically pushed to Zookeeper via Orchestrator callback scripts and a Taiji agent that performs health checks on databases. In less than a second, these changes are pushed to ProxySQL, so our application will seamlessly begin sending read and write queries to the proper database.

Bryana Knight - GitHub

While GitHub isn't the biggest database around in terms of the amount of data we hold in MySQL, it is among the top 50 busiest sites on the internet. Facing an immediate need to distribute load, we came up with creative ways to move a significant amount of traffic off of our main MySQL cluster, with no user impact. Moving five of our hottest tables required collaboration between engineers, DBAs and SRE. This talk will describe when and how to do it, and prove it to be an efficient database scalability solution.

Moving tables required changes to our database infrastructure as well as our application. I'll explain the impetus for this work and why we did it. We'll walk through the application-level changes that allowed us to change connections while still serving data. Then, I'll discuss the ways we moved tables to different clusters, using MySQL replication, or in some cases, temporary sharding and copying billions of rows. Finally, I'll outline the orchestration of the actual cutovers.

There are substantial improvements in the Optimizer in MySQL 8.0. Most noticeably, we have added support for advanced SQL features like common table expressions, windowing functions and grouping() function. We also made DBAs' lives easier with invisible indexes, and additional hints that can be used together with the query rewrite plugin.

On the performance side, cost model changes will make a huge impact. We have made JSON support even more powerful by adding JSON table function, aggregation functions and more. Come and learn about new features in MySQL 8.0!

The full title of this presentation should be: "Save some bandwidth by not transmitting the full resultset metadata over the wire when you don't need it. " Indeed, one the latest features in the MySQL protocol allows you to save some network bandwidth by not sending the metadata with the resultsets for which you know the metadata.

Join this talk to learn how to turn this on, and how much data does it save per query.

Shuhao Wu - Shopify Inc.

Existing tools like mysqldump and replication cannot migrate data between GTID-enabled MySQL and non-GTID-enabled MySQL -- a common configuration across multiple cloud providers that cannot be changed. These tools are also cumbersome to operate and error-prone, thus requiring a DBA's attention for each data migration. We introduced a tool that allows for easy migration of data between MySQL databases with constant downtime on the order of seconds.

Inspired by gh-ost, our tool is named Ghostferry and allows application developers at Shopify to migrate data without assistance from DBAs. It has been used to rebalance sharded data across databases. We plan to open source Ghostferry at the conference so that anyone can migrate their own data with minimal hassle and downtime. Since Ghostferry is written as a library, you can use it to build specialized data movers that move arbitrary subsets of data from one database to another.

Alexey Kopytov - .

This talk is about measuring and reducing noise in benchmark results. Properly tuning the operating system and hardware to achieve stable results in benchmarks becomes an art in itself these days. There may be many reasons for that:

- jitter in CPU and I/O schedulers
- dynamic CPU frequency scaling
- process address space randomization
- kernel configuration
- etc.

If you are not seeing stable results in your performance comparisons, you are wasting your time. Since I do a lot of MySQL benchmarks as a part of my job, I have collected a number of recipes to measure and reduce system noise and achieve more stable numbers in benchmarks. I'm going to describe those recipes as well as the new sysbench module implemented to automate those tasks and simplify system tuning for other people.

Orchestrator uses Raft consensus as of version 3.x. This setup improves the high availability of both the orchestrator service itself as well as that of the managed topologies and allows for easier operations.

This session will briefly introduce Raft consensus concepts, and elaborate on orchestrator's use of Raft: from leader election, through high availability, cross DC deployments and DC fencing mitigation, and lightweight deployments with SQLite.

Of course, nothing comes for free, and we will discuss considerations to using Raft: expected impact, eventual consistency and time-based assumptions.

Orchestrator/Raft is running in production at GitHub, Wix and other large and busy deployments.

Determining the best and most suitable relational database management system (RDBMS) for a given project isn't an easy task and can be rather challenging at times. It is like benchmarking fast cars created by different racing teams!

The presentation will compare, using a large body of experimental results, two highly-available cloud closed-source products: Amazon Aurora MySQL and RDS MySQL. Both are based on the Open Source MySQL Edition.
Both use cases have demonstrated that MySQL is a great solution for concurrent writes, reads and read and write traffic.

Additionally, both scenarios have proven to be successful, satisfying data integrity, reliability and scalability with different outcomes.
