             Summary: CEP-46: SSTable import support for witnesses
                 Key: CASSANDRA-20967
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-20967
             Project: Apache Cassandra
          Issue Type: Sub-task
          Components: Feature/Lightweight Transactions
            Reporter: Ariel Weisberg


Mutation tracking added support for SSTable import where the mutation tracking 
log has an entry for the import action for the sstables that are staged on 
disk. This allows read repair to be done for reads that include the imported 
sstables.

On witnesses this record needs to be aware of witnesses and validate that the 
witness does not import out of range data. This validation should occur both 
for the initial sstable important and processes that are staging the sstables 
and then also when applying the record out of the MT log.
