This talk introduces Shard-Query, an MPP distributed parallel processing middleware solution for MySQL.
Shard-Query is a federation engine which provides a virutal "grid computing" layer on top of MySQL. This can be used to access data spread over many machines (sharded) and also data partitioned in MySQL tables using the MySQL partitioning option. This is similar to using partitions for parallelism with Oracle Parallel Query.
This talk focuses on why Shard-Query is needed, how it works (not detailed) and the best schema to use with it. Shard-Query is designed to scan massive amounts of data in parallel.
