We had a great response to our call for papers, thank you! However great we believe having the conference in Austin, TX will be, moving to a new area of the US is still a leap of faith until we see the numbers. So we’re thankful that so many of you continue to support and take part in our Open Source Database Conference. We have great plans for the event going forward, and look forward to sharing them with you.

In fact, one new initiative is already underway. Instead of having one relatively small committee that reviews all of the papers for all tracks, we are taking a different approach this year. Each track is led by a Percona engineer or manager in the role of “Track Champion”, and they each are establishing a Track Steering Committee to review the submissions for that one track.

There are many benefits to this approach. First of all, it means that folk with in-depth knowledge of a technology review a smaller number of …

During our recent consulting with one of our client, We came across an interesting issue on RDS. The baseline is that “Low IO size on your RDS instance can affect your DB performance”.  Yes, It’s IO size, Not IOPS.

We had our production systems running on RDS MySQL with a single master, 3 replicas. All instances are of same type db.m4.4xlarge with same parameter group configuration and the disk size is 1.5 TB. According to the AWS user guide, each of these instances can support up to 4500 (sustained IOPS) guaranteed IOPS.

Find below the Write IOPS graph for all the instances.

It’s understood that Write IOPS / pattern on Master can vary when compared with Slave, due to a lot of factors like binlog row format, log writing etc. But it has to be almost similar for all the slaves given that it …
