Version: ACE 5

Release 25.6

Cache service is redis by default

So far ACE used Redis cache if Redis connection details were configured, otherwise no cache was used. Starting with this release it's necessary to explicitly configure ACE_CACHE_SERVICE=none if cache is not used, otherwise it will result in cache connection errors as redis is the default cache service.

Configuration changes​

See configuration for more details.

  • ACE_CACHE_SERVICE - new variable to select cache service (redis (default), couchbase, none)
