Hadoop BoF Session at OSCON
+0 Vote Up -0Vote Down

I have a BoF session next week at OSCON next week:

Migrating Data from MySQL and Oracle into Hadoop

The session is at 7pm Tuesday night – look for rooms D135 and/or D137/138.

Correction: We are now in  E144 on Tuesday with the Hadoop get together first at 7pm, and the Data Migration to follow at 8pm.

I’m actually going to be joined by Gwen Shapira from Cloudera, who has a BoF session on Hadoop next door at the same time, along with Eric Herman from Booking.com. …

Check for MySQL slave lag with Percona Toolkit plugin for Tungsten Replicator
+0 Vote Up -0Vote Down

A while back, I made some changes to the plugin interface for pt-online-schema-change which allows custom replication checks to be written. As I was adding this functionality, I also added the --plugin option to pt-table-checksum. This was released in Percona Toolkit 2.2.8.

With these additions, I spent some time writing a plugin that allows Percona Toolkit tools …

Replicating Oracle Webinar Question Follow-up
+0 Vote Up -0Vote Down

We had really great webinar on Replicating to/from Oracle earliest this month, and you can view the recording of that Webinar here.

A good sign of how great a Webinar was is the questions that come afterwards, and we didn’t get through them all. so here are all the questions and answers for the entire webinar.

Q: What is the overhead of Replicator on source database with asynchronous CDC?

A: With asynchronous operation there is no substantial CPU overhead (as with synchronous), but the amount of generated …

A New Home for Tungsten in the UK
+0 Vote Up -0Vote Down

I was suitably heartened to hear about the new mine opening up in the Devon here in the UK to mine the element Tungsten.

I comment on this to my associates at Continuent, where comments were made by Csaba as to the appropriate quotes in the article:

“Tungsten is an extraordinary metal.”

“It’s almost as hard as a diamond and has one of the highest melting points of any mineral.”

“Adding a small amount to steel makes it far harder, far more resistant to stress and heat. The benefits to industry are obvious.”

Leading …

Continuent at Hadoop Summit
+1 Vote Up -0Vote Down

I’m pleased to say that Continuent will be at the Hadoop Summit in San Jose next week (3-5 June). Sadly I will not be attending as I’m taking an exam next week, but my colleagues Robert Hodges, Eero Teerikorpi and Petri Versunen will be there to answer any questions you have about Continuent products, and, of course, Hadoop replication support built into Tungsten Replicator 3.0.

If you are at the conference, please go along and say hi to the team. And, as always, if there are any questions please let them or me know.


Cross your Fingers for Tech14, see you at OSCON

So I’ve submitted my talks for the Tech14 UK Oracle User Group conference which is in Liverpool this year. I’m not going to give away the topics, but you can imagine they are going to be about data translation and movement and how to get your various databases talking together.

I can also say, after having seen other submissions for talks this year (as I’m helping to judge), that the conference is shaping up to be very interesting. There’s a good spread of …

Revisiting ZFS and MySQL
+1 Vote Up -0Vote Down

While at Percona Live this year I was reminded about ZFS and running MySQL on top of a ZFS-based storage platform.

Now I’m a big fan of ZFS (although sadly I don’t get to use it as much as I used to after I shutdown my home server farm), and I did a lot of different testing back while at MySQL to ensure that MySQL, InnoDB and ZFS worked correctly together.

Of course today we have a completely new range of ZFS compatible environments, not least of which are FreeBSD and ZFS on Linux, I think it’s time to revisit some of my original advice on using this combination.

Unfortunately the …

Tungsten Replicator 3.0 is Cloudera Enterprise 5 Certified
+0 Vote Up -0Vote Down

One of the key platforms I’ve been testing on for the MySQL to Hadoop replication has been Cloudera, largely driven by customer requirements, but it’s also one of the easiest way to get started with Hadoop.

What I’m even more pleased about is the fact that we are proud to announce that Tungsten Replicator 3.0 is certified for use on the new Cloudera Enterprise 5 …

Continuent Replication to Hadoop – Now in Stereo!
+0 Vote Up -0Vote Down

Hopefully by now you have already seen that we are working on Hadoop replication. I’m happy to say that it is going really well. I’ve managed to push a few terabytes of data and different data sets through into Hadoop on Cloudera, HortonWorks, and Amazon’s Elastic MapReduce (EMR). For those who have been following my long association with the IBM InfoSphere BigInsights Hadoop product, and I’m pleased to say that it’s working there too. I’ve had to adapt Robert’s original script to work with the different versions of the underlying Hadoop tools and systems to make it compatible. The actual performance and process is unchanged; you …

Real-Time Data Loading from MySQL to Hadoop with New Tungsten Replicator 3.0
