             Summary: Ensure SAI works w/ Transient Replication/Witness Replicas
                 Key: CASSANDRA-19267
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-19267
             Project: Cassandra
          Issue Type: Task
          Components: Feature/SAI
            Reporter: Caleb Rackliffe


Transient replication (see CASSANDRA-14404) and SAI should work together 
without specific integration. However, some exploratory testing is probably 
warranted, and there may be some details around the selection of SSTable 
indexes at transient replicas that may be worth inspecting. As of 
CASSANDRA-19018, SAI has a mechanism to separate repaired and urepaired SSTable 
indexes during its local queries. While repaired data should be removed from 
transient replicas, it still might be a good idea to avoid looking at repaired 
SSTables altogether if we can (and especially if the removal of repaired data 
lags at all, creating a window where we look at it unnecessarily).
