------------------------------------------
Summary: 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: Bug
Reporter: Carl Yeksigian
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.
