I reproduced the same problem in a simple staging environment, I deleted every
ledger and stopped writing new entries.
I’m trying to do a little debug and I see that in Journal.java there is this
line
if (!(checkpoint instanceof LogMarkCheckpoint)) {
return; // we didn't create this checkpoint, so dont do anything
with it
}
Actually my test bookie gets a
org.apache.bookkeeper.bookie.CheckpointSource$Checkpoint$1@98aabc2<mailto:org.apache.bookkeeper.bookie.CheckpointSource$Checkpoint$1@98aabc2>
class instead of a LogMarkCheclpoint, when the
checkpoint is done in the SynchThread#checkpoint method at every FlushInterval
hope this can help

Oggetto: Re: Journal file never deleted
The journal files are only deleted when its corresponding data in ledger
storage is flushed. What is your rate on adding entries? How many .txn files
you have?

I’m running all the default values, except from maxbackups which I set to 1
Even if a delete every ledger the logs never get deleted.
I enabled level DEBUG for every logger but I get no useful hint.
Normally at which rate logs file should be deleted ?
Thanks

Hi Enrico,
Have you had a look at the journal settings here?

Hi,
I’m running BookKeeper 4.3.0 (and 4.3.1). I noticed that journal files (*.txn
files) never get deleted. I’m using ServerConfiguration.setMaxBackupJournals(1)
and default flushinterval of 1 second.
I’m running “embedded” bookies, that is that I launch the bookie inside another
JVM, with the following code:
ServerConfiguration conf = new ServerConfiguration();
conf.setBookiePort(port);
conf.setUseHostNameAsBookieID(true);
conf.setJournalDirName(logDir.getAbsolutePath());
conf.setZkServers(zookeeperServer);
conf.setLedgerDirNames(Arrays.stream(dataDirs).map(File::getAbsolutePath).collect(Collectors.toList()).toArray(new
String[dataDirs.length]));
conf.setFlushInterval(1000);
conf.setAutoRecoveryDaemonEnabled(false);
…
conf.setMaxBackupJournals(1);
…
this.bookie = new BookieServer(conf);
this.bookee.start();
any suggestion ?
thanks
