Vishal K commented on ZOOKEEPER-872:
------------------------------------
Is there any reason why we dont have a findNRecentLogs(int n) method to return
the n most recent logs (similar to findNRecentSnapshots)?
While testing I noticed that it can happen that a log file is left undeleted
depending on the transaction id of the nth snapshot file. Thus, we will have n
snapshots, but n+1 log file left behind instead of n. This file will be deleted
after the next snapshot is taken.
We won't have this problem if we have a function that keeps the n most recent
logs and removes the rest.
