Recent Changes

The following changes were made to reflect new features for the v2.3 release:

• TLS is now supported for the CQL API.
• The doradus.yaml configuration option dbauthenticator and the corresponding SimpleAuthenticator algorithm is no longer supported for authentication with Cassandra.
• The Doradus server now supports a “memory” appender for log details. Configuring this option in the log4j.properties file and accessing memory-based log records is described.
• Documentation for downloading, compiling, and running Doradus in various modes has been updated.
• Doradus now supports multi-tenant operation using tenant-specific keyspaces. Documentation for this feature has been added.
• New OLAP performance options cam be configured in doradus.yaml: olap_merge_threads and olap_compression_threads. These features can significantly improve OLAP shard merging performance.
