Marcus Eriksson updated CASSANDRA-19056:
----------------------------------------
Test and Documentation Plan: internal ci run
Status: Patch Available (was: Open)
https://github.com/krummas/cassandra/commit/f395c60bc73e89714f31c741b51953e07ff93ce1
the reason is a race between creating the MV while we have ongoing writes - the
MV is first added to TableViews before the schema is activated by committing
the transformation. Patch just checks the cluster metadata if the MV is in the
schema before it starts taking writes.
ci coming soon
