----------------------------------------
Summary: One way targeted repair
Key: CASSANDRA-9876
URL: https://issues.apache.org/jira/browse/CASSANDRA-9876
Project: Cassandra
Issue Type: Improvement
Reporter: sankalp kohli
Priority: Minor
Many applications use C* by writing to one local DC. The other DC is used when
the local DC is unavailable. When the local DC becomes available, we want to
run a targeted repair b/w one endpoint from each DC to minimize the data
transfer over WAN. In this case, it will be helpful to do a one way repair in
which data will only be streamed from other DC to local DC instead of streaming
the data both ways. This will further minimize the traffic over WAN. This
feature should only be supported if a targeted repair is run involving 2 hosts.
