This release is anchored by performance and compression enhancements.

Here is a list of major changes:

  • Compression
    • Prevent OutOfMemoryError on Cassandra when compression job runs (HWKMETRICS-520)
    • Avoid compression job executing in a loop when execution falls behind (HWKMETRICS-536)
    • Avoid future executions of compression job from not running if Cassandra is shutdown abruptly (HWKMETRICS-518)
    • Added a flag to disable the compression job; the data will be persisted and retrieved without compression (HWKMETRICS-524)
    • The block size for compression is now configurable (HWKMETRICS-545)
    • The compression job can now be triggered manually (HWKMETRICS-502)
  • Server Clustering

    • Schema updates are correctly applied when multiple servers are started at the same time (HWKMETRICS-514)
    • Added Cassandra connection information to the status page and created an admin version with detailed Cassandra cluster information (HWKMETRICS-526)
    • Internal system metrics are now persisted under admin tenant; this gives a good overview of the current system load (HWKMETRICS-550)
  • REST API
    • Added endpoint to allow fetching of available tag names (HWKMETRICS-532)
