Ariel Weisberg updated CASSANDRA-14405:
---------------------------------------
Description:
Add support to CQL and NTS for configuring keyspaces to have transient replicas.
Add syntax allowing a keyspace using NTS to declare some replicas in each DC as
transient.
Implement metadata internal to the DB so that it's possible to identify what
replicas are transient for a given token or range.
Introduce Replica which is an InetAddressAndPort and a boolean indicating
whether the replica is transient. ReplicatedRange which is a wrapper around a
Range that indicates if the range is transient.
Block altering of keyspaces to use transient replication if they already
contain MVs or 2i.
Block the creation of MV or 2i in keyspaces using transient replication.
