Replication stars
+3 Vote Up -0Vote Down

Working with replication, you come across many topologies, some of them sound and established, some of them less so, and some of them still in the realm of the hopeless wishes. I have been working with replication for almost 10 years now, and my wish list grew quite big during this time. In the last 12 months, though, while working at Continuent, some of the topologies that I wanted to work with have moved from the cloud of wishful thinking to the firm land of things that happen. My quest for star replication starts with the most common topology. One master, many slaves.

Benchmarking Tungsten Parallel Replication
+4 Vote Up -0Vote Down

Tungsten parallel apply on slaves, or parallel replication for short, has been available for about a year.   Until recently we did not have many formal benchmarks of its performance.  Fortunately the excellent Percona Live Conference in London accepted my talk on Tungsten parallel replication (slides available here), so Giuseppe Maxia and I finally allocated a block of time for …

I will be a speaker at Percona Live - London 2011, and I am looking forward to the event, which is packed with great content. A whopping 40 session of MySQL content, plus 3 keynotes and 14 tutorials. It's enough to keep every MySQL enthusiast busy. Continuent speakers will be particularly busy, as between me and Robert Hodges, we will be on stage four times …

Quick Installation of Replication from MySQL to MongoDB
+3 Vote Up -0Vote Down

Proof-of-concept Tungsten support for MongoDB arrived last May, when I posted about our hackathon effort to replicate from MySQL to MongoDB.  That code then lay fallow for a few months while we worked on other things like parallel replication, but the period of idleness has ended.  Earlier this week I checked in fixes to Tungsten Replicator to add …

Upgrading Tungsten Replicator: as easy as ...
+3 Vote Up -0Vote Down

When I talked about the usability improvements of Tungsten Replicator, I did not mention the procedure for upgrading. I was reminded about it by a question in the TR mailing list, and since the question was very relevant, I updated the Tungsten Cookbook with some quick upgrading instructions. A quick upgrading procedure is as important as the installer. Since we release software quite often, either because we have scheduled features to release or because of bug fixes, users want to apply a new …

My three MySQL sessions at OOW 2011 - and much more

Oracle Open World 2011 is approaching. MySQL is very well represented. Sheeri has put together a simple table of all the MySQL sessions at OOW, which is more handy than the Oracle schedule. I will be speaking in three sessions on Sunday, October 2nd.

Chaining Replication Clusters
+2 Vote Up -0Vote Down

MySQL built-in replication includes a concept called relay slave, which allows you to create hierarchical database clusters. You can do the same thing with Tungsten, and this can be done in more than one way. Let's start with two distinct clusters. We can follow the recipes in the Tungsten Cookbook to install a …

Quick recipes for database cluster building
+4 Vote Up -0Vote Down

One lesson learned in more than two decades working in this industry is that most of the IT professionals are impatient, want to achieve results immediately, and, most importantly, they don't read documentation. Much as the average geek is happy to answer many requests with a dismissive RTFM, the same geeks are not as diligent when it comes to learning about new or updated technologies. For this reason, there is a kind of documentation that is very much appreciated by busy and impatient professionals: cookbooks. And I am not talking about food. Geeks are not known for being cooks …

A Glance at Real-Time Replication From MySQL To Oracle
+5 Vote Up -0Vote Down


Intro
The open source Tungsten Replicator is very powerful. It's exciting to see how a flexible initial design allows to push the boundaries of replication with each new release. The recently published System of Record approach for multi-master databases does exactly this for multi-master databases.

What's Next for Tungsten Replicator
+3 Vote Up -0Vote Down

As Giuseppe Maxia recently posted we released Tungsten Replicator 2.0.4 this week.  It has a raft of bug fixes and new features of which one-line installations are the single biggest improvement.  I set up replicators dozens of times a day and having a single command for standard cluster topologies is a huge step forward.  Kudos to Jeff Mace for getting this nailed down.

So what's next?  You can get see what we are up …
