---------------------------------

             Summary: KahaDB Scheduler log files not being deleted
                 Key: AMQ-7281
                 URL: https://issues.apache.org/jira/browse/AMQ-7281
             Project: ActiveMQ
          Issue Type: Bug
          Components: KahaDB
    Affects Versions: 5.15.9, 5.15.4
         Environment: RHEL 7.6 x86_64
jdk1.8.0_172
            Reporter: Sergiy Dryga
         Attachments: kahadb_log_1.txt, scheduler_log_1.txt

Dear Support Team!

I faced with a problem with KahaDB Scheduler, it doesn't delete old log files. It looks similar to previously reported issue AMQ-6152, see 'scheduler_log_1.txt'. But after testing I noticed that it's not the same problem, KahaDB Scheduler deletes not used files well.

Investigation also showed that the most old file contains pending message, it's ok. But there are a lot of files without any panding messages. I assumed that it contains ACK and added enableAckCompaction="true" and compactAcksIgnoresStoreGrowth="true" to the config:

<persistenceAdapter>
 <kahaDB
 directory="${activemq.data}/static-broker/kahadb"
 journalMaxFileLength="1mb"
 cleanupInterval="60000"
 enableIndexWriteAsync="true"
 journalDiskSyncStrategy="never"
 enableAckCompaction="true"
 compactAcksIgnoresStoreGrowth="true"
 indexCacheSize="100000"
 indexWriteBatchSize="5000"
 checkForCorruptJournalFiles="true"
 ignoreMissingJournalfiles="true" />
 </persistenceAdapter>

And yes, it looks like KahaDB started to move ACK, see 'kahadb_log_1.txt'.

But it doesn't work with KahaDB Scheduler, it's not possible to specify ACK compaction options in 'jobSchedulerStore' config section:

<jobSchedulerStore>
 <bean xmlns="http://www.springframework.org/schema/beans" id="jobSchedulerStore" class="org.apache.activemq.store.kahadb.scheduler.JobSchedulerStoreImpl">
 <property name="directory" value="${activemq.data}/static-broker/scheduler" />
 <property name="journalMaxFileLength" value="1000000"/>
 </bean>
 </jobSchedulerStore>

How is it possible to solve this problem?
