MemSQL 6.0 Beta 3 introduces enhancements to manageability and resiliency, as well as exception handling support for extensibility. It also includes the enhancements to query processing and extensibility that were introduced in Betas 1 and 2, with up to 80X performance improvement for group-by/aggregate queries.

Manageability and resiliency enhancements include:

  • Reduced blocking
  • Ability to use any aggregator to run data definition language statements
  • Enhanced fault tolerance for leaf failover and ALTER TABLE

Benefits include fewer situations that require manual intervention, simplified application development, and improved availability.
