-------------------------------------------
1. This goes way back to benedicts main concept
https://issues.apache.org/jira/browse/CASSANDRA-6477?focusedCommentId=14039757&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14039757
We have each replica on the base table send the mv update to a single mv
replica. So replicas are "paired" 1:1
2. Since the coordinator is a BL against a QUORUM of all base replicas which
will always send to MV replicas we have a lot more work todo than a only
sending a failed base to view update.

> Local indexes are suitable for low-cardinality data, where spreading the
> index across the cluster is a Good Thing. However, for high-cardinality
> data, local indexes require querying most nodes in the cluster even if only a
> handful of rows is returned.
