The Proxy Wars - MySQL Router, ProxySQL, MariaDB MaxScale

Session presented at Oracle Developer Live - MySQL, 2020. Recording available at https://developer.oracle.com/developer-live/mysql/ Abstract: MySQL Shell is the new, advanced command-line client and editor for MySQL. It sends SQL statements to MySQL server, supports both the classic MySQL protocol and the newer X protocol, and provides scripting capabilities for JavaScript and Python. But there's more to MySQL Shell than meets the eye. It delivers a natural and powerful interface for all DevOps tasks related to MySQL by providing APIs for development and administration. This session covers MySQL Shell's core features, along with demonstrations of how to use the various APIs and how to extend MySQL Shell. We’ll address the regular interaction with databases, the built-in tools that make DBAs and developers’ lives easier, the easy and flawless set up of HA architectures, and the plugins and extensions framework.

This presentation is about MySQL Shell and how effectively Database Engineers and Database Administrators.

Bart Oles - Severalnines AB Organizations need an appropriate disaster recovery plan to mitigate the impact of downtime. But how much should a business invest? Designing a highly available system comes at a cost, and not all businesses and indeed not all applications need five 9's availability. We will explain fundamental disaster recovery concepts and walk you through the relevant options from the MySQL & MariaDB ecosystem to meet different tiers of disaster recovery requirements, and demonstrate how to automate an appropriate disaster recovery plan.

Built-in MySQL Replication is known for its capability to enable to scale reads easily. However, there are some limitations and known issues with this solution because of the asynchronous nature of this replication. This talk will describe another way of doing MySQL replication, by using synchronous replication, available in Percona XtraDB Cluster. The open source solution will be explained and compared to traditional asynchronous MySQL replication, as well as some known use cases will be described. Percona XtraDB Cluster is an, open source, high availability and high scalability solution for MySQL clustering. Features include: Synchronous replication, Multi-master replication support, Parallel replication, Automatic node provisioning.

In this tutorial, we cover the different deployment possibilities of the MySQL architecture depending on the business requirements for the data. We also deploy some architecture and see how to evolve to the next one. The tutorial covers the new MySQL Solutions like InnoDB ReplicaSet, InnoDB Cluster, and InnoDB ClusterSet.

This document provides an overview and comparison of MySQL InnoDB Cluster and MySQL InnoDB ReplicaSet. It discusses the components, goals, and features of each solution. MySQL InnoDB Cluster uses Group Replication to provide high availability, automatic failover, and data consistency. MySQL InnoDB ReplicaSet uses asynchronous replication and provides availability and read scaling through manual primary/secondary configuration and failover. Both solutions integrate MySQL Shell, Router, and automatic member provisioning for easy management.

Frédéric Descamps presented on the state of MySQL in 2022. Some key points included: - MySQL 8.0.29 was the latest release with improvements like IF NOT EXISTS for DDL statements. - MySQL remains the most popular open source database according to surveys. - MySQL HeatWave on OCI provides high performance for analytics workloads compared to other cloud offerings. - The MySQL Operator for Kubernetes makes it easier to deploy and manage MySQL on Kubernetes. - Upcoming certifications for MySQL 8.0 DBA and Developer were announced.

MySQL Clustering over InnoDB engines has grown a lot over the last decade. Galera began working with InnoDB early and then Group Replication came to the environment later, where the features are now rich and robust. This presentation offers a technical comparison of both of them.

MaxScale is a database proxy that provides load balancing, connection pooling, and replication capabilities for MariaDB and MySQL databases. It can be used to scale databases horizontally across multiple servers for increased performance and availability. The document provides an overview of MaxScale concepts and capabilities such as routing, filtering, security features, and how it can be used for operational tasks like query caching, logging, and data streaming. It also includes instructions on setting up MaxScale with a basic example of configuring read/write splitting between a master and slave database servers.

MySQL InnoDB Cluster provides a complete high availability solution for MySQL. It uses MySQL Group Replication, which allows for multiple read-write replicas of a database to exist with synchronous replication. MySQL InnoDB Cluster also includes MySQL Shell for setup, management and orchestration of the cluster, and MySQL Router for intelligent connection routing. It allows databases to scale out writes across replicas in a fault-tolerant and self-healing manner.

The document discusses the Performance Schema in MySQL. It provides an overview of what the Performance Schema is and how it can be used to monitor events within a MySQL server. It also describes how to configure the Performance Schema by setting up actors, objects, instruments, consumers and threads to control what is monitored. Finally, it explains how to initialize the Performance Schema by truncating existing summary tables before collecting new performance data.

The document discusses two MySQL high availability solutions: MySQL InnoDB Cluster and MySQL NDB Cluster. MySQL InnoDB Cluster provides easy high availability built into MySQL with write consistency, read scalability, and application failover using MySQL Router. MySQL NDB Cluster is an in-memory database that provides automatic sharding, native access via several APIs, read/write consistency, and read/write scalability using the NDB storage engine. The document compares the two solutions and discusses their architectures and key features.
