Benedict Elliott Smith updated CASSANDRA-19313:
-----------------------------------------------
Resolution: Fixed
Status: Resolved (was: Triage Needed)
> Accord: Reduce overhead of NotifyWaitingOn with a WaitingToExecute SaveStatus
> -----------------------------------------------------------------------------
>
> Key: CASSANDRA-19313
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19313
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Accord
> Reporter: Benedict Elliott Smith
> Priority: Normal
>
> Long execution graphs can do a lot of duplicated work invoking
> {{NotifyWaitingOn}} repeatedly on a transaction that is already waiting on a
> dependent transaction to execute. This can easily be avoided by introducing a
> {{SaveStatus}} that indicates the transaction is actively managing its
> dependencies for execution.
