Thank you very much We got a work-around for our problem. Our bookies could not run Compaction due to errors on listing /ledgers.
It was not possible to scan list of ledgers in any way because of zookeeper limits (see https://issues.apache.org/jira/browse/BOOKKEEPER-39 and similar issues) Our work-around is to scan ledgers list doing a “blind” ledgerId scan from 1 to 1.700.000 in order to find existing ledgerIDs and then dropping ledger which were no more in use. We found that a procedure was “leaking” ledgers, it was never dropping ledgers, so our system got overhelmed. Once the clean up operation completed the Compation run instantly and we released several GBs of space on bookies Now the list of ledgers is really more affordable by FlatLedgersManager and so we have some more time We would like to migrate to HierarchicalLederManager anyway in order not to have such problems in the future, provided that our systems are growing and bookkeeper is one of the fundamental pieces or our infrastructure -- Enrico Da: Sijie Guo [mailto:[email protected]] Inviato: giovedì 17 dicembre 2015 19:41 A: [email protected] Oggetto: Re: BOOKKEEPER-878 Hello Enrico: Sorry for the delays.
