Yesterday someone opened a Launchpad question asking "is Drizzle dead?".  I have answered that question on Launchpad but wanted to blog about it to give a bit of background context.

In fact Drizzle has influenced many Open Source projects today.  Openstack's Continuous …

For the longest time, I've been wanting to update my own site. I work on so many things but my own site is not one of them. I keep promising to do something and get pulled into working on some project or my young children need something (every few minutes!). Recently, my friend Brian pointed me to something that removes any sort of reason for wanting to procrastinate: Jekyll and Github Pages.

Jekyll makes it much easier to update the site-- using my favorite editor vim. Yes, I have to do a few ruby-ish things, but that's OK, despite being a Perl (and now Python) guy. You get to my age and realize they are all essentially similar tools trying to solve variants of the same problem. It's all just bits, right?

My plan with this site is to post technical stories on a regular basis. Yes, I said "regular", and I will hold my own feet to …

Will be giving a lightning talk at Percona Live 2014 – santa clara :)

In the world of replication, The Binlog is every ones favorite. 

But what about the Relay log, Don't you feel it can do more ?

Yes, It can. How about, if it can serve the purpose of the GTID 

feature without GTID.

I spoke last month at linux.conf.au 2014 in Perth, Australia, and one of my sessions focused on the “Continuous Integration (CI) testing of Percona XtraDB Cluster (PXC)” at the Developer,Testing, Release and CI miniconf.

I blogged a couple of weeks ago about my upcoming MySQL/Hadoop talk at SCaLE 12X. Unfortunately I had to cancel. A few days after writing the article I came down with an eye problem that is fixed but prevents me from flying anywhere for a few weeks. That's a pity as I was definitely looking forward to attending the conference and explaining how Tungsten replicates transactions from MySQL into HDFS.

Meanwhile, we are still moving at full steam with Hadoop-related work at Continuent, which is the basis for the next major replication release, Tungsten Replicator 3.0.0. Binary builds and documentation will go up in a few days. There will also be many more public talks about Hadoop support, starting in April at …

Taxonomy upgrade extras: galeraclustercustomer

We are very satisfied with the functionality and the launch. The entire Cluster is running absolutely stable. This is a significant advantage for our customers because we are able to offer our services without interruption. We will use Galera in further projects and convert our existing Master/Slave installations.
