Unreleased

5.9.1 - 2024-06-13

Fixed

  • Fixes a bug that results in some metrics not appearing on the HTTP endpoints. (#231)
  • Updates metriken and histogram dependencies. (#230)

5.9.0 - 2024-06-12

Changed

  • Moved metrics file exposition settings to separate config section. (#221)
  • Default metrics interval is now one second. (#222)
  • Updated Momento SDK to version 0.39.7. (#223)

5.8.0 - 2024-05-22

Changed

  • Kafka client improvements including TLS and compression support. (#208)

Added

  • A /quitquitquit handler for graceful early termination. (#212)

5.7.0 - 2024-04-23

Changed

  • OpenSSL is now the default SSL/TLS provider. BoringSSL is still available through the use of feature flags. (#194)

Added

  • Support for configuring the interval for file exposition allowing for finer resolution artifacts. (#192)
  • Approximate compression ratio for message and value payloads. (#191)
  • Support the list_remove command for Momento. (#198)
  • New metrics for dropped requests. (#201)

5.6.0 - 2024-04-03

Changed

  • metriken-exposition is updated which results in differences for the file-based metric exposition. (#185 #187)
  • Metrics reporting for both stdout and file output are now roughly aligned to the top of the second. This allows easier correlation with other metric artifacts. (#188)

Fixed

  • h2 updated to address RUSTSEC-2024-0019

5.5.0 - 2024-03-27

Added

  • Support for writing metrics to a Parquet file.

Fixes

  • Updates mio to address RUSTSEC-2024-0019

5.4.0 - 2024-02-09

Added

  • Advanced ratelimit controller that can produce ramps, loops, mirrored ramps, and random steps.
  • Latency percentiles now include max latency and are included in the json output.

Fixed

  • Fixes incorrect implementation of list_length for Momento.

5.3.0 - 2023-11-21

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.

5.2.0 - 2023-10-17

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

5.1.0 - 2023-08-23

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.

5.0.0 - 2023-07-25

Changed

  • Rewritten implementation of rpc-perf using Tokio to improve support for protocols where async libraries are prevelant.

Added

  • Support Momento topics.
  • Basic HTTP/1.1 and HTTP/2.0 load generation.
