Improved support for transactions

This release of MemSQL has improved transaction capabilities and introduces support for multi-statement transactions. Multi-statement transactions allow a set of DML statements to be combined into a single transaction. For more information on transactions in MemSQL see: What isolation levels does MemSQL provide?

Improvements to the column store

MemSQL 3.2 adds support for extremely efficient queries against tables using a column store index through the introduction of sorted segments and segment elimination. This release also supports highly efficient joins between tables using column store indexes (including self-joins of a single table). For more information about how to take advantage of the MemSQL column store including the new features in MemSQL 3.2 see Columnstore.
