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.…

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 …

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!

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.…

A new version of the Group Replication plugin for MySQL is available now. The newest release is available on Mac OS X, Solaris, and FreeBSD.

Additional platform support has been made possible via a new group communication implementation. This new communication system supports communication of messages between servers on many platforms, allowing MySQL to embrace the diversity of the MySQL community and enables Group Replication for more people on more platforms.…

MySQL 5.7 has been recently declared Generally Available and in it there is a set of new replication features. Over the last 6 years MySQL replication has evolved at a tremendous pace. MySQL 5.6 brought us a lot of new replication features, many that were ground breaking and yes, sometimes controversial.…

The MySQL Fabric team is pleased to announce that a new version is now available on Labs. This labs release includes our latest developments to give you a taste of what we have been working on. In particular, it includes the following new features and improvements:

• Multi-node Fabric support is now available! This means that multiple fabric nodes can be started and any node can be contacted to perform operations. This allows Fabric itself to be fault-tolerant (no single point of failure) and distribute request across multiple Fabric nodes. For more information, see: Increasing MySQL Fabric Resilience to Failures: Meet the Multi-Node Fabric 
• Improved security password management, allowing password to not be passed in plain text in the command line or configuration files. …

Overview

Redundancy is key to providing resilience to failures, and in Fabric 1.6.2 (now available on MySQL Labs), we have introduced the possibility to start multiple MySQL Fabric instances that are kept consistent through a replicated state machine.

The state machine replication guarantees that all machines (i.e.…
