-------------------------------------
Component/s: Materialized Views
> Materialized Views filter paired endpoints to local DC even when not using DC-aware replication
> -----------------------------------------------------------------------------------------------
>
> Key: CASSANDRA-10634
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10634
> Project: Cassandra
> Issue Type: Bug
> Components: Coordination, Materialized Views
> Reporter: Joel Knighton
> Assignee: Joel Knighton
> Fix For: 3.0.0
>
>
> When calculating paired view replicas on MV writes, we filter out base and view replicas that aren't in the local datacenter.
> If we are using SimpleStrategy, this filtering is incorrect, since our replica placement is not datacenter aware.
> We should behave the same as DC-aware consistency levels and only perform this datacenter-aware filtering if the replication strategy is an instance of NetworkTopologyStrategy.
