# TODO
#   Manual purge




--echo Test expire-log-days handling as part of normal operation
--echo Logs are rotated as part of transaction COMMIT (to avoid
--echo a transaction being split across 2 files), rotation checks
--echo expire-logs-days to decide whether to purge, and purging
--echo calls into the Ndb handler to think about deleting rows
--echo from ndb_binlog_index.
--echo The delete from ndb_binlog_index is itself a SQL statement
--echo executing *during* the COMMIT of some other transaction,
--echo potentially in some other engine.  Don't want to think
--echo about that too closely
