0.5.0

What's Changed

• improved new redis sample generation by @Llandy3d in #51
• make EXPIRE_KEY_TIME configurable by @Llandy3d in #53
• Prom patching by @Llandy3d in #54

---

• New improved implementation of _generate_samples for MultiProcessRedisBackend:

  • Improved performance for generating metrics
  • Fixed a bug where on multiprocess on some scrapes a metric wouldn't be picked up due to missing local collector child
  • Now on labeled metrics, the labels/value combination will be initialized to 0 if it doesn't exists (before only the key would be initialized)

• Redis keys expire time can now be configured via the expire_key_time config passed when loading the backend

• Experimental prometheus_client patching in-place to quickly test the library on existing codebases

• DEPRECATED: key_prefix for redis configuration. Prefer a side-car container or a separate redis/redis db per service.
