How to speed up reads from bookie

Hi, I'm wondering how to speed up reads from BookKeeper. "Tail" reads are very fast because they hit Bookie cache, but when I need to scan the full content of a ledger performances are in general very poor. Is it only a matter of disks or is there any Bookie parameter tuning possible ? Thank you

Bookkeeper Backup and Disaster Recovery

Hi, I would like set up an effective disaster recovery system for BookKeeper. The case of a single bookie unrecoverably lost is not a problem "by design", we use replication for such an issue. So my case is that all bookies in the same cluster are lost (datacenter disaster). From my point of vie

Re: Can't create ledger

Liu, From your logs I see that the client is able to reach ZooKeeper, so I think that createLedger should complete. Are you sure that your program is not stuck at “addEntry” ? Is your client machine able to connect to the bookies ? You can dump the stacktrace of the JVM with jstack I suggest you
