ScyllaDB Enterprise 2018.1.5 Release Announcement

ScyllaDB Enterprise 2018.1.5 is a minor release of the enterprise NoSQL database that primarily addresses bug fixes for the 2018.1 branch, along with significant enhancements to single partition scans. Customers are advised to upgrade to this version while coordinating with the ScyllaDB support team, though they should be aware that the downgrade procedure differs from previous versions. The release resolves multiple issues, including problems with CQL operations like DISTINCT queries, user-defined type keyspace drops, and certain partition scans, as well as addressing performance and stability concerns such as latency spikes and infinite loops in specific scenarios. Additionally, a new monitoring counter for speculative retries has been introduced.
