[jira] [Created] (CASSANDRA-18653) Avoid unnecessary index builds and validations

Mike Adamson created CASSANDRA-18653:
----------------------------------------

             Summary: Avoid unnecessary index builds and validations
                 Key: CASSANDRA-18653
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-18653
             Project: Cassandra
          Issue Type: Improvement
          Components: Feature/SAI
            Reporter: Mike Adamson
            Assignee: Mike Adamson


In the testing of CASSANDRA-18490 it was noted that the SSTableAddedNotification will trigger an index build that will always build the column index components even if they already exist and are valid. 

The same notification is also handled by the StorageAttachedIndexGroup that can validate the components. This can lead to the components being validated more than is necessary.

We should coordinate these notification handlers so there is no overlap of responsibility.
