MemSQL 6 – Release Candidate

MemSQL 6.0 RC 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, 2,  and 3 with up to 80X performance improvement for group-by/aggregate queries.
Manageability and resiliency enhancements include:
  • Enhanced fault tolerance for leaf failover, master aggregator failover, and ALTER TABLE
  • Reduced blocking for backups, ALTER TABLE, leaf failover, and system management operations
Benefits include fewer situations that require manual intervention, simplified application development, and improved availability.
