---------------------------------------
Summary: All Nodes Replication Strategy
Key: CASSANDRA-12629
URL: https://issues.apache.org/jira/browse/CASSANDRA-12629
Project: Cassandra
Issue Type: Improvement
Reporter: Alwyn Davis
Priority: Minor
Fix For: 3.7
When adding a new DC, keyspaces must be manually updated to replicate to the
new DC. This is problematic for system_auth, as it cannot achieve LOCAL_ONE
consistency (for a non-cassandra user), until its replication options have been
updated on an existing node.
Ideally, system_auth could be set to an "All Nodes strategy" that will
replicate it to all nodes, as they join the cluster. It also removes the need
to update the replication factor for system_auth when adding nodes to the
cluster to keep with the recommendation of RF=number of nodes (at least for
small clusters).
