This is used to isolate the queries from reading the directory until > compaction has finished and to avoid the compactor marking used earlier. In > case of replication, during bootstrap , directory is copied as it is with the > same name from source to destination cluster. But the directory created by > compaction with txn id can not be copied as the txn list at target may be > different from source. The txn id which is valid at source may be an aborted > txn at target. So conversion logic is required to create a new directory with > valid txn at target and dump the data to the newly created directory. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
