Patrick Hunt commented on ZOOKEEPER-1107:
-----------------------------------------
Can you give some rational for this change? Is PTL not sufficient?
Also see this JIRA, which would make such changes obsolete: ZOOKEEPER-323
here are some reasons I can remember we do it this way:
1) keep things simple, eg cron job with a basic script that could do whatever
it likes re cleanup - thereby conforming to whatever requirements the operator
might have (which will typ be very different from the concerns of the
developers)
2) don't cleanup unless the operator explicitly requests - ensures we don't
lose data, say the operator is backing up every month, but the default is for
zk to cleanup every hour (etc...)
I don't see a problem with adding this as long as it's off by default, obv
configurable through the zk config file. What sorts of functionality would be
provided by this feature?
