[jira] [Created] (GEODE-7756) Performance Degradation on Clusters with CQs Introduced in GEODE-6989

             Summary: Performance Degradation on Clusters with CQs Introduced in GEODE-6989
                 Key: GEODE-7756
                 URL: https://issues.apache.org/jira/browse/GEODE-7756
             Project: Geode
          Issue Type: Bug
          Components: cq, querying
            Reporter: Juan Ramos


On clusters with running {{CQs}}, a performance degradation was introduced by GEODE-6989 for regular cache operations.

Every time an entry is updated on the cache, Geode internally (and synchronously) executes the registered {{CQs}} on the event entry to determine whether the subscribed clients should be notified or not. Due to the changes introduced through GEODE-6989, these regular cache operations now takes longer than expected (build internal cache key, check internal cache, and  subsequent put if needed), reducing the throughput ~ %10.
