Have compactor open a transaction and run the job in that transaction. # make compactor produced base/delta include this txn id in the folder name, e.g. base_7_c17 where 17 is the txnid. # add {{CQ_TXN_ID bigint}} to COMPACTION_QUEUE and COMPLETED_COMPACTIONS to record this txn id # make sure {{AcidUtils.getAcidState()}} pays attention to this transaction on read and ignores this dir if this txn id is not committed in the current snapshot ## this means not only validWriteIdList but ValidTxnIdList should be passed along in config (if it isn't yet) # once this is done, {{CompactorMR.createCompactorMarker()}} can be eliminated and {{AcidUtils.isValidBase}} modified accordingly # modify Cleaner so that it doesn't clean old files until new file is visible to all readers # -- This message was sent by Atlassian JIRA (v7.6.3#76005)
