Description

bookie server aggregates entries into entry log file. suppose there is lots of ledgers, each ledger has little messages. so a entry log file would contains messages from lots of different ledgers. if there is only one ledger not be deleted, the entry log file would not be removed, whose occupied disk space could not be reclaimed.
