On Monday afternoon, Neal Armitage and I will be speaking at Percona Live in London. It will be a three hours tutorial about Tungsten replicator.
The contents of this tutorial are mostly new. We have released recently a new and easier way of installing different topologies, in the shape of cookbook scripts, which are distributed with the replicator tarball.
Using this cookbook, any user can simply install multiple topologies, from the simple master/slave to all-masters, fan-in, and star.
There are recipes for showing the replication cluster, switching roles between master and a chosen slave, taking over MySQL replication, installing direct slaves with parallel replication, testing each topology, and[Read more...]
Tungsten Replicator version 2.0.6 was released today.
You can get both the binaries and the source code at the project's downloads page.
This release contains many bug fixes, and various improvements. All of them are listed in the Release Notes. The most interesting ones are the improvement in multi-master topologies. Using this release with star topologies you will get less traffic than before, because we have reduced some duplication of transaction history logs that were sent between servers.
And speaking of multi-master topologies, this release includes the cookbook recipes mentioned in this blog[Read more...]
Attached are the slides for my MySQL Connect talk Evaluating MySQL High-availability alternatives, which I will present today at 14:30 at the MySQL Connect conference.
A bit unusually I'm posting the material ahead of the talk. The point of the talk is about evaluating each alternative from your own perspective. With that in mind, if you're at the talk with your own laptop, feel free to browse the slides at your own pace from here.
This month I have joined the team at Continuent. No stranger to the MySQL ecosystem, Continuent provides replication and clustering technology for managing data between MySQL, Oracle, PostgreSQL, Vertica and a growing list of data stores.
I have known many of the team at Continuent for some time, and will again be joining Giuseppe Maxia from our days at MySQL Inc/AB starting back in 2006.
I am looking forward to taking the hard work out of administration of MySQL systems with the simplicity of Continuent Tungsten, simplifying tasks including automatic failover, multi-master and geo cluster redundancy to a single command.
Catch me speaking at the upcoming[Read more...]
