Webinar on Read/Write Splitting with PHP

I’ll be presenting a webinar next Wednesday, January 23 at 10 a.m. (Pacific Time), about issues application developers should think about for scaling out read-query traffic using multiple MySQL instances in a replication pair.

Multi-Data Center MySQL with Continuent Tungsten: Dec. 11 webinar

MySQL 5.6 vs MySQL 5.5 and the Star Schema Benchmark

[…]

Distributed Set Processing with Shard-Query

Actually he asked if it could scale to 50, but testing 20 was all I could due to to EC2 and time limits. I think the results at 20 nodes are very useful to understand the performance: […]

The data in the each image is split into 20 “shards”. This blog post will refer to an EC2 instances as a node from here […]

Innodb row size limitation

I recently worked on a customer case where at seemingly random times, inserts would fail with Innodb error 139. This is a rather simple problem, but due to it’s nature, it may only affect you after you already have a system running in production for a while.
