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 just use a different JS-based batchloader script to work with different tools.

Robert has also been simplifying some of the core functionality, such as configuring some fixed pre-determined formats, so you no longer have to explicitly set the field and record separators.

I’ve also been testing the key feature of being able to integrate the provisiong of information using Sqoop and merging that original Sqooped data into Hadoop, and then following up with the change data that the replicator is effectively transferring over. The system works exactly as I’ve just described – start the replicator, Sqoop the data, materialise the view within Hadoop. It’s that easy; in fact, if you want a deeper demonstration of all of these features, we’ve got a video from my recent webinar session:

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

If you can’t spare the time, but still want to know about our Hadoop applier, try our short 5-minute video:

While you’re there, check out the Clustering video I did at the same time:

And of course, don’t forget that you can see the product and demos live by attending Percona Live in Santa Clara this week (1st-4th April).
