tysonnorris opened a new issue #4626: Allow limiting DB bloat by excluding response from Activation record in some cases
URL: https://github.com/apache/openwhisk/issues/4626
 
 
   Using a single db for many tenants that use web/blocking actions, we end up with:
   * lots of Activation documents for blocking actions that are never used (on success, the response is consumed immediately, never looked up from db)
   * lots of responses that vary in size, sometimes quite large (~1MB)
   
   We plan to introduce a PR to:
   * disable response storage for blocking+successful+not timed out (60s) Activation records
   * introduce a ?debug param for action developers to use to force persistence of the response (even in case of blocking+successful+not timed Activations)
   * introduce config flags to enable these response handling and debug options; default would be disabled
   
   Need to investigate potential problems with sequence/composition usage (so scope of actions where response would be disabled, may include these as well).
