Laxman commented on ZOOKEEPER-1107:
-----------------------------------
Thanks very much for your review and update Pat.
{quote}having the period specified in minutes rather than hours{quote}
1) In our case we have gone for this approach as disk is running out of space
after long run say 30 days and even longer. Initially we thought of providing
purge interval in days. But, considering the testability and your point of
finer level of granularity only we have gone for hours.
2) Say, for 3 days interval, user would prefer to configure 72 (hours) rather
4320 (minutes). Just trying to balance usability and granularity.
Please let me know your thoughts on this. If you feel we need more granularity
for some other usecase, surely I can update the patch.
{quote}(my reading of TimerTask indicates that only a single purge operation
would be running at any time, ie they will not run concurrently if I set the
interval to be 1 minute and it takes more than a minute to purge, can you
confirm?){quote}
Yes, verified the behavior of Java Timer. Timer will be running in one single
thread and no two invocations will be running concurrently. Verified the same
through debug points.
