ScyllaDB Enterprise Release 2019.1.1

ScyllaDB Enterprise 2019.1.1 is a minor yet significant update to the ScyllaDB Enterprise 2019.1 branch, aimed at enhancing security and performance for its users. This release introduces encryption at rest, allowing on-disk data such as SSTables, commit logs, and batch logs to be encrypted, though centralized key management is not yet available. Additionally, ScyllaDB Enterprise is now accessible as a Docker instance and as an EC2 AMI, expanding its deployment options. A new BYPASS CACHE clause has been added for SELECT statements, optimizing performance for range scans by bypassing the cache for data that is unlikely to be accessed frequently. The update also addresses several bug fixes, including issues with the "mc" SSTable file format, range scan anomalies, and the TimeWindowCompactionStrategy, aimed at minimizing potential performance hindrances.
