v5.3.0

Changed

• Metrics endpoints now use a configurable integration period controlled by the
  value for the interval in the general config section. This means that
  percentile metrics will be reflect the behavior across that period of time.
• Use rustcommon compact histogram instead of the local implementation.

Added

• Support for benchmarking Apache Kafka.

Fixed

• Early connection attempts are now reflected in the stats for the first window.

v5.2.0

Changed

• Metrics library (metriken) updated to replace heatmaps with histograms,
  which reduces cost on the metrics write path.

Added

• Dataspec now supports merging of histograms.

Fixed

• RUSTSEC-2023-0065

v5.1.0

Added

• rpc-perf can now generate zrange commands with the by_score option for both
  the momento and redis protocols.
• Dataspec crate which allows easy consumption of JSON output.

Changed

• rpc-perf will now set TCP_NODELAY by default on all TCP connections it
  creates.
• The default buffer size for the memcached client has been increased from 4KB
  to 16KB.

Fixed

• Hit/miss statistics in the output json will now have their correct values
  instead of always being 0.
