MemSQL is a transactional database (system of record).

Spark is a way of processing data, ideally stored in a system of record (Hive/HDFS/S3/MemSQL etc).

They're not the same.

There are similarities. A database is also a way of processing data.

For the kinds of processing both Spark and MemSQL do (e.g. join operation) is Spark faster than MemSQL?
