🔅 MemSQL 7.0 Release Candidate is now available for download!

We are happy to announce the availability of MemSQL 7.0 Release Candidate – you can download it here.

Release Highlights

  • Much improved performance of synchronous replication and durability. Our synchronous replication now has only a minor performance penalty compared to our already fast asynchronous replication – giving you better data consistency guarantees without incurring large performance penalties. You can read more about our improved synchronous replication here.
  • Selective queries on columnstore tables now run faster, via sub-segment access.
  • Hash indexes on columnstore tables are now supported. CREATE TABLE and ALTER TABLE now support adding and dropping hash indexes on columnstore tables.
  • By default, UPDATE and DELETE queries now lock columnstore tables at the row level, allowing improved concurrency. Previously, these queries locked columnstore tables on the segment level.
  • Sparse rowstore compression is now supported.
  • Queries on columnstore tables can now reorder filters to decrease execution time. Reordering occurs automatically and allows filters that are more selective to be evaluated first.
