Jonathan Ellis updated CASSANDRA-10405:
---------------------------------------
Priority: Minor (was: Major)
> MV updates should optionally wait for acknowledgement from view replicas
> ------------------------------------------------------------------------
>
> Key: CASSANDRA-10405
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10405
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Carl Yeksigian
> Priority: Minor
> Labels: materializedviews
> Fix For: 3.x
>
>
> MV updates are currently completely asynchronous in order to provide
> parallelism of updates trying to acquire the partition lock. For some use
> cases, leaving the MV updates asynchronous is exactly what's needed.
> However, there are some use cases where knowing that the update has either
> succeeded or failed on the view is necessary, especially when trying to allow
> read-your-write behavior. In those cases, we would follow the same code path
> as asynchronous writes, but at the end wait on the acknowledgements from the
> view replicas before acknowledging our write. This option should be for each
> MV separately, since MVs which need the synchronous properties might be mixed
> with MV which do not need this.
