Subject [jira] [Updated] (CASSANDRA-9967) Determine if a Materialized View is finished building, without having to query each node
Date Thu, 27 Aug 2015 16:28:47 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-9967?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis updated CASSANDRA-9967:
--------------------------------------
    Fix Version/s:     (was: 3.0.0 rc1)
                   3.x

I don't think we can scope creep the original request ("without having to query each node")
into 3.0.

I don't think we want every node in the cluster querying every other node for MV progress.
 And we can't just assume that originating coordinator is the master, because it might go
down before the MV is finished.  Which means we need to elect a mv master to do this.  (Or
better yet a push model instead of pull, which also requires master election.)

Pushing to 3.x unless someone has a better idea very very quickly.

> Since MVs are eventually consistent with its base table, It would nice if we could easily
know the state of the MV after its creation, so we could wait until the MV is built before
doing some operations.
