MemSQL Spark Connector

February 2015

We released the MemSQL Spark Connector, giving users the ability to read and write data between MemSQL and Apache Spark. MemSQL can easily handle the high rate of inserts and reads that Spark often requires, while also having enough space for all data that Spark can create.

The MemSQL Spark Connector comes with a number of optimizations, such as reading data out of MemSQL in parallel and making sure that Spark collocates the data in its cluster with MemSQL nodes as much as possible. It also provides two main components: a MemSQLRDD class for loading data from a MemSQL query and a saveToMemsql function for persisting results to a MemSQL table.
