Changelog

Unreleased

6.2.1 - 2024-02-23

  • Fix issue in OTP 26 and Elixir 1.15 by not using to_existing_atom in configuration

Changed

6.2.0 - 2024-01-31

  • Ensure Elixir version is ~> 1.13 #79.

6.1.0 - 2022-06-13

Changed

  • Updgrade dependency packages
  • Merged #41 resulting in ETC without GenServer (and therefore better performance)
  • Merged #46 remove additional whitespace
  • Updated Docs based on #45
  • Adds CREDITS.md

6.0.0 - 2018-10-12

Changed

  • Change the ETS backend to throw an error if either expiry_ms or cleanup_interval_ms config values are missing. This should have been fixed ages ago.
  • Default :pool_max_overflow changed to 0. It's a better default, given that some users have seen weird errors when using a higher overflow. In general, capacity should be increased by using a higher :pool_size instead
  • Changed how the ETS backend does cleanups of data, should be more performant.

5.0.0 - 2018-05-18

Added

  • A new check_rate_inc function, which allows the caller to specify the integer with which to increment the bucket by. This is useful for limiting APIs which have some notion of "cost" per call.

4.0.0 - 2018-04-23

Changed

  • Use a worker-pool for the backend (via poolboy), this avoids bottle-necking all traffic through a single hammer process, thus improving throughput for the system overall

Added

  • New configuration options for backends:
    • :pool_size, determines the number of workers in the pool (default 4)
    • :pool_max_overflow, maximum extra workers to be spawned when the system is under pressure (default 4)
  • Multiple instances of the same backend! You can now have two ETS backends, fifteen Redis's, whatever you want

3.0.0 - 2018-02-20

Changed

  • Require elixir >= 1.6
  • Use a more sane supervision tree structure

2.1.0 2017-11-25

Changed

  • Add option to use more than one backend
  • Add option to suppress all logging

2.0.0 - 2017-09-24

Changed

  • New, simpler API
    • No longer need to start backend processes manually
    • Call Hammer.check_rate directly, rather than useing a macro
  • Hammer is now an OTP application, configured via Mix.Config

1.0.0 - 2017-08-22

Added

  • Formalise backend API in Hammer.Backend behaviour

0.2.1 - 2017-08-10

Changed

  • Minor fixes
