--------------------------------------------------
Summary: Accord: Reduce overhead of NotifyWaitingOn with a
WaitingToExecute SaveStatus
Key: CASSANDRA-19313
URL: https://issues.apache.org/jira/browse/CASSANDRA-19313
Project: Cassandra
Issue Type: Improvement
Components: Accord
Reporter: Benedict Elliott Smith
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.
