MySQL Group Replication: A Quick Start Guide

With the new Group Replication Beta release—0.8 for MySQL 5.7.14—available for download on labs.mysql.com, I expect more and more people to begin engaging in various forms of proof-of-concept attempts. So I wanted to create a “quick start guide” (to replace this outdated getting started post) focused on an example/test Linux environment, that covers how to get started, what a full working example test setup can look like, and also include some best practice and operations advice along the way.…

MySQL Group Replication for 5.7.14

Hi everyone! It has been some time since the last MySQL Group Replication labs release was out. But the team has not been sitting on its hands. As such, it is time for a new labs release with new features, bug fixes and improvements across the board.…

Webinar Thursday June 23: Choosing a MySQL High Availability Solution Today

Please join Percona, Technical Account Manager, Michael Patrick on Thursday, June 23, 2016 at 10 AM PDT (UTC-7) as he presents “Choosing a MySQL High Availability Solution Today.”

High availability (HA) is one of the solutions to improve performance, avoid data outages, and recover quickly from disasters. An HA environment helps guarantee that your database doesn’t have a single point of failure, accommodates rapid growth and exponentially increasing database size, and enables the applications that power your business.

Michael will discuss various topologies for achieving High Availability with MySQL.

Topics include:

  • Percona XtraDB Cluster
  • DRBD
  • MHA
  • MySQL Orchestrator

Each solution has advantages and …

Group Replication — an Overview

Within the MySQL team, we’re extremely excited about Group Replication! More and more of our users are also starting to become aware of this exciting feature–which offers native (virtually) synchronous replication with support for multi-master or active/active update-anywhere replication clusters. Our developers and users alike are eager to see easy, native HA come to MySQL!…

Extend MySQL Master HA (MHA) capabilities with MHA Helper

I have used many tools starting with MMM to be able to manage MySQL replication clusters. Some of the tools require additional tools and complex HA solutions such as Pacemaker and Corosync, or Zookeeper. While other tools do not do the failover well which leaves the slaves in an inconsistent state, MMM would be an example. And I must say that of all the tools I love MySQL Master HA (MHA) the most. MHA is a great tool to manage MySQL replication clusters for the purpose of HA. The most important thing about MHA is that it tries to take...

MySQL 5.7 Multi-Source Replication – Automatically Combining Data From Multiple Databases Into One

MySQL’s multi-source replication allows you to replicate data from multiple databases into one database in parallel (at the same time). This post will explain and show you how to set up multi-source replication. (WARNING: This is a very long and detailed post.…

MySQL HA Solution … We have it or not ?

Data is the most important asset any organization has especially those who belongs to web, mobile, social, enterprise and cloud applications.

Availability refers to the ability to cope with, and if necessary recover from, failures on the host, including failures of MySQL, the operating system, or the hardware and maintenance activity that may otherwise cause downtime.

Because each application has different operational and availability requirements, MySQL offers a range of certified and supported solutions, delivering the appropriate levels of High Availability (HA). 

Factors to consider for HA Solution: 

  • Operational Capabilities
  • Budgetary Constraints
  • The level of availability required (In terms of Time)
  • The type of application being deployed
    • Mission critical services …

Voting for talks at the Percona Live Data Performance Conference 2016

So this year the Percona Live conference has a new name — it is the “Data Performance Conference” (presumably for a much broader appeal and the fact that Percona is now in the MongoDB world as well). And the next new thing to note? You have to go through a process of “community voting”, i.e. the speaker has to promote their talks before via their own channels to see how many votes they can get (we tried this before at the MySQL & Friends Devroom at FOSDEM; in this case, please remember you also need to create a new account and actually vote while logged in).

I hope you vote for Sergei, Monty and my proposals!

Good Leaders are game changers: Raft & Paxos

Introduction

Consensus is a key component to providing fault-tolerant services such as synchronously replicated data stores, non-blocking atomic commitment and Paxos and Raft are among the most popular consensus algorithms. Paxos has been widely studied by researchers while Raft has become very popular among engineers.…

State of automated recovery via Pseudo-GTID & Orchestrator @ Booking.com

This post sums up some of my work on MySQL resilience and high availability at Booking.com by presenting the current state of automated master and intermediate master recoveries via Pseudo-GTID & Orchestrator.

Booking.com uses many different MySQL topologies, of varying vendors, configurations and workloads: Oracle MySQL, MariaDB, statement based replication, row based replication, hybrid, OLTP, OLAP, GTID (few), no GTID (most), Binlog Servers, filters, hybrid of all the above.

Topologies size varies from a single server to many-many-many. Our typical topology has a master in one datacenter, a bunch of slaves in same DC, a slave in another DC acting as an …
