Sharding and Things We'd Like To See Improved
Starting with MongoDB version 5.0, we can reshard a collection using the new shard key. But there are still something we think could be improved like:
  • Cluster metadata lack of details on chunks
  • TTL indexes
  • Improvements in the rebalancing process
  • Performance issues on rebalancing data
  • Observability

Database Reliability Engineering for MySQL
A common request that we get from our clients is to make MySQL highly available or to enhance existing architecture. We have standardized our approach by combining a proxy layer, for traffic redirection, a topology management tool, for master failover/switchover, and some additional tools to glue together both layers.

The Road Toward an Open Database Performance Ranking
Understanding the performance of different databases is crucial for building efficient, data-intensive applications. Benchmarking possible databases is a valid option for enabling such comparison, yet, it is a major challenge due to heterogeneity in the resource, database, and workload level.

To enable an on-demand comparison of cloud-hosted databases, we present a database performance ranking as an open dataset that is created with the Benchmarking-as-a-Service platform benchANT. This ranking will be continuously extended to cover the latest advancements in the cloud resource, database, and benchmark domain.

The Development of Cloud-native Database GaussDB for MySQL
GaussDB for MySQL is a cloud-native database system based on MySQL 8.0. It uses the "log is the database" paradigm and separates compute and storage. It takes the full advantages of a computational storage system with flexible consistency models for superior performance and availability. Further, the system offloads certain query operators down to the storage layer to reduce data movement. The development of a multi-master system is also underway.

This talk will cover the following topics:
  • Overview of the GaussDB for MySQL architecture
  • Design and implementation of near data processing (NDP)
  • Development of cloud-native multi-master
  • Performance results
  • Future directions

Building an Open Source MongoDB-compatible Database on Top of PostgreSQL
MongoDB is a life-changing technology for many developers, empowering them to build applications faster than using relational databases. However, MongoDB abandoned its open source roots, changing the license to SSPL and making it unusable for many open source and commercial projects. We decided to change that, so we started working on FerretDB – an open-source proxy, written Go, that accepts connections and handles queries from unmodified MongoDB clients, and stores data in PostgreSQL.

In our talk, we will discuss our reasoning for starting this project, our vision, the current state of FerretDB, some interesting implementation details, and our plans for the future.

Better MySQL With Percona Monitoring and Management
Optimizing MySQL performance, troubleshooting MySQL problems, and managing backups are the most critical and challenging tasks for MySQL DBAs in their daily routine. The databases powering your applications need to be able to handle changing traffic workloads while remaining responsive and stable so that you can deliver an excellent user experience. At the same time, modern database vendors demonstrate a trend of moving away from traditional deployment methods to DBaaS, which means DBAs are also expected to find cost-efficient means of solving these issues.

In this presentation, we will demonstrate the advanced options of PMM that enable you to solve these challenges. We will show how to get the DBaaS experience built on free and open-source software. We will look at specific, common MySQL problems and review them.

Build a Powerful Alerting Platform by Integrating Alertmanager With PMM
Percona Monitoring and Management (PMM) is known for its great monitoring functionality. However, its integrated alerting capability, as of now implemented, is limited and sometimes complex to manage.

The Alertmanager handles alerts sent by client applications. It takes care of deduplicating, grouping, and routing them to different receivers such as email, PagerDuty, or OpsGenie. With PMM and Alertmanager combined, you can build a powerful monitoring and alerting system that will alert you through multiple communication channels if either a simple health check fails or in case of a pattern change that may indicate an issue.

Postgres and the Artificial Intelligence
Artificial intelligence, machine learning, and deep learning are intertwined capabilities that attempt to solve problems that defy traditional computational solutions --- problems including fraud detection, voice recognition, and search result recommendations. While they elude simple computation, they are computationally expensive, involving the calculation of perhaps millions of probabilities and weights. These computations can be done outside the database, but there are specific advantages of doing machine learning inside it, close to where the data is stored. This presentation explains how to do machine learning inside the Postgres database.

The Lost Art of Database Design
The scalability of your application and your database is only as good as the database design you put behind it.  Designing your schema, the database structures, and planning for the future need to happen early and needs to evolve over time.  In today's rapid pace development cycles, the database design is often overlooked or even dismissed entirely.  Databases and marketing teams tout "Schemaless Designs", database as a service, and new tech that makes caring about databases a thing of the past.  I will explain why database design is as important as ever and I will give you the 8 things you need to design on every application regardless of which database or service you use.

PostgreSQL in the Cloud: DBaaS vs Kubernetes
Applications in the cloud on Kubernetes are very common these days. Most of the time, they need a database (like PostgreSQL). There are two often considered alternatives:
1. Use DBaaS - for example, Google CloudSQL for PostgreSQL
2. Deploy the database on Kubernetes with the application

We'll compare those approaches from different angles to clarify the differences. You'll be better equipped to decide how to run PostgreSQL for your cloud-native application. We'll focus on Google CloudSQL and Percona Distribution for PostgreSQL Operator on Google Kubernetes Engine (GKE). Still, most of the knowledge is universal across cloud platforms and DBaaS solutions.

Using Roles and Partial Revokes To Improve Security in MySQL 8.0
For many years MySQL had a problem with managing granular privileges: Anyone who had all privileges on a MySQL system database could grant all other privileges, including "grant option" and "super." That complicated managing privileges and resulted in a less secure setup. MySQL 8.0 introduced 3 critical features: 1. partial revokes 2. splitting SUPER privilege to more granular set and 3. roles.

Venmo had 44% YoY TPV growth in 2021. Traffic growth and new product features resulted in many scalability challenges, including higher database connections, especially during high-velocity events throughout the year.

This talk will describe how we used proxy solutions for MongoDB and Aurora-MySQL to scale with traffic, various alternatives explored and driving factors narrowing down to a chosen approach. We will share how we migrated the traffic via proxy with zero downtime, challenges faced and solutions applied to achieve our goals. You can take away valuable lessons learned and get tips on how you could tackle similar challenges in your organization.

Vitess VReplication: Standing on the Shoulders of a MySQL Giant
Vitess provides a large set of features that allow you to use and manage a scalable set of MySQL database instances across custom partitions or shards of your dataset as if it was a single logical database. One of the key components used within Vitess is called VReplication.

In this talk, we'll cover what VReplication is and how it relates to MySQL replication, including how VReplication leverages the technologies you're already familiar with while expanding on them to add a set of powerful primitives and abstractions that support an ever-growing list of high-level features such as sharding and resharding of tables, materialized views, online DDL, change streams (CDC), and message or job queues.

This talk should leave a MySQL user/operator with a good understanding of what VReplication could do for them and when they may want to use it.

Solving PostgreSQL Wicked Problems: Oriole DB Inc.
PostgreSQL is one of the most popular DBMSes in the world. But we can see a set of wicked problems in PostgreSQL design, which came from Berkley or were added in very early development stages. Those problems are very annoying for users and aren't resolved for decades: bloat, xid wraparound, write-amplification, and more.

Miraculously, with just a small patch to PostgreSQL core extending this API, it appears possible to solve wicked PostgreSQL problems in a new engine made within an extension. This talk covers how the new engine is integrated with PostgreSQL Core and solves the wicked PostgreSQL problems.

Tune PostgreSQL for Read/Write Scalability
PostgreSQL is one of the leading open-source databases. Out of the box, the default PostgreSQL configuration is not tuned for any particular workload. Nowadays, production systems have quite expensive machines, which require extra configuration. PostgreSQL provides configuration parameters to configure it accordingly. Most of the time, people configure PostgreSQL according to hardware and don’t consider the workload and type of queries. In all these three cases, there’s a different set of configurations. In this talk, users will see how to configure PostgreSQL for a Read/Write intensive load. This talk will explain every important configuration parameter with real-time examples.

MongoDB Magical Live Resharding – Considerations and Concerns
One of the biggest pains with MongoDB has been handling problems caused by picking bad shard keys when sharding to scale out horizontally as your application needs and data size grow. Suboptimal shard keys cause performance problems relating to disk imbalance, disk I/O, and issues with CPU and memory.

MongoDB first addressed this with refinable shard keys in v4.4 and now with live resharding in v5.0.  This highly requested feature took time, effort, changes to the core server and WiredTiger engine. However, it is not all magic and healthy bunnies coming out of the hat. Let’s take a deeper look.

MySQL in the Cloud: DBaaS vs Kubernetes
Applications in the cloud on Kubernetes are very common these days. Most of the time, they need a database (like MySQL). There are two often considered alternatives:
1. Use DBaaS - for example, Google CloudSQL for MySQL
2. Deploy the database on Kubernetes with the application

We'll compare those approaches from different angles to clarify differences. You'll be better equipped to decide how to run MySQL for your cloud-native application. We'll focus on Google CloudSQL and Percona Distribution for MySQL Operator on Google Kubernetes Engine (GKE).  Still, most of the knowledge is universal across cloud platforms and DBaaS solutions.

The InnoDB Cluster is a great HA solution that often is deployed alongside asynchronous replication to achieve a multi-datacenter Disaster Recovery. With 8.0.27 MySQL shell, this was greatly simplified with the release of MySQL InnoDB ClusterSet.

In this session, we will look at the MySQL InnoDB ClusterSet and how it can simplify managing the MySQL InnoDB Cluster disaster recovery. We will walk through the process of setting it up, managing multiple clusters, and how to perform a switchover/failover. Lastly, we will discuss its use cases and limitations.

Extending Percona Monitoring and Management With Custom Collectors
In this session, we'll review how you can make the most out of the extensibility of PMM's custom data collectors. Be it with queries running directly in the monitored databases, or with external scripts that can gather OS-related data, PMM is all about power and freedom to implement things yourself! Additionally, we'll review how to integrate the newly collected data within PMM's native dashboards, and discuss the caveats and limitations behind this approach.

Migrating Meta to MySQL 8.0
MySQL powers some of Facebook’s most important workloads. We actively develop new features in MySQL to support our evolving requirements which change many different areas of MySQL, including client connectors, storage engine, optimizer, and replication. Each new major version of MySQL requires significant time and effort to migrate our workloads. The challenges include: porting our custom features, minimizing changes needed for application queries, and fixing performance regressions.

In this talk, we will share our story about how we went about achieving the migration from 5.6 → 8.0 for our workloads at Meta.

Cleaning the Room - Everything You Need To Know About Vacuum
Vacuum is a very important but largely misunderstood topic in Postgres world, but we will change it now! We will dive deep into the Postgres storage system and its multi-version model (MVCC) during this presentation to give us the needed base to understand what is and why we need Vacuum.

We will then discuss the Vacuum, its implementation, what it does, how it does its job, and also the Autovacuum, the automated keeper that is in charge keeping everything clean and tidy, as well as the settings related to it and how it can influence performance (for good or for bad).

Advanced Data Types in PostgreSQL
The “Tour de Data Types” talk provided an overview of the rich set of basic data types in PostgreSQL. But there are more data types available, which can and should be used in applications. PostgreSQL also allows you to combine simple types into more complex structures, or create your very own data type.

This talk starts with ENUM types, and how to create and use them. From there we will discover Arrays and Composite types, look into Range types and finally learn how you can create your own data type.

PostgreSQL Query Performance Insights
Understanding query performance patterns are essentially the foundation for query performance tuning. It, in many ways, dictates how a database cluster evolves. And then there are direct and indirect cost connotations as well.

With improved observability, using the right tools, you can get the best out of your existing setup and ensure that it is able to handle not only the average load profile but peak load as well. We'll see how different tools like pg_stat_activity, pg_stat_statements, auto_explain, pgBadger, and pg_stat_monitor can deliver a complete picture to help measure, analyze and optimize your queries and database system.

Evaluating PostgreSQL Compatibility in Distributed SQL Databases
Google Spanner announced support for PostgreSQL, validating the importance of such compatibility. But many distributed SQL databases have taken radically different approaches. This has major implications for developers.

We will examine the degree of compatibility across four databases: Google Spanner, Amazon Aurora, CockroachDB, and YugabyteDB.

The Paradigm Shift - Understanding the Move To Distributed Databases
Databases still face one monumental challenge.  Despite all the features, all of the capabilities, and advanced data parsing, the modern SQL RDBMS maintains data integrity by storing data in a single controlled location.

Distributed databases break that barrier. Using the consensus technology that underpins blockchain, an emerging group of databases - like PingCAP TiDB, Cockroach DB, and YugabyteDB - are bringing SQL compliant distributed data storage to the general cloud.

We will discuss the underlying technologies that enable distributed databases, the current state of the technology, and cover some of the considerations for current and future development projects.

A Deep Dive Into PostgreSQL Indexing
Indexes are a fundamental feature of relational databases, and  PostgreSQL offers developers and designers a rich collection of options. To take advantage of these entirely, users need to understand the basic concept of indexes to compare the different index types and apply them to different application scenarios. Only then can you make an informed decision about your database index strategy and design. One thing is for sure: Not all indexes are appropriate for all circumstances, and using a ‘wrong’ index can have the opposite effect to what you intend. Armed with more advanced knowledge, you can avoid this worst-case scenario!

Going the distance
In every DBA's life, there is a point where data needs to be copied over great distances. This can be the other coast, or it can be another continent.  It can be because of implementing a disaster recovery system, it can be because distant read replicas are needed for the application.

In this talk, we use examples with MySQL and xtrabackup to discuss the issues of long-distance copies and the potential performance tuning opportunities. In this talk, we will:

Examine the characteristics of transferring a large amount of data over WAN links.
Discuss compression and encryption options.
Check out options for copying an already existing backup.
Check out options for streaming backups.

A Survey of MySQL Indexes Types
Adding an index to a table is a popular way to try and speed up queries. But MySQL has several types of indexes and many options.  Which is best for your need? Do you need to ignore indexes for hash joins? Can functional indexes help the optimizer plan for a better query? And how do you test an index's effectiveness? This session will detail what you need to know to configure the best possible index for the needs of your applications in a simple and concise fashion.

How To Ease Major MySQL Upgrades!
For a variety of reasons, including new features, performance benefits, bug fixes, and so on, it is essential to upgrade MySQL to the most recent version. Databases with obsolete versions are vulnerable. Major version upgrades, on the other hand, can be problematic if they haven't been well tested with your application, as the procedure may break it, render it inoperable, or cause performance issues. The goal of this talk is to go over the details of how to make major MySQL upgrades easier!
