Active MQ uses KahaDB, while activeMQ.xml configured to use MsSQL
Hello!
I'm using active MQ 5.15.4 with Apache Camel 2.22.0.
My activemq.xml configured to use MsSQL for persistence:
<persistenceAdapter>
<jdbcPersistenceAdapter dataSource="#mssql-ds"
createTablesOnStartup="true"/>
</persistenceAdapter>
Active MQ correctly uses MySQL, but periodically it creates KahaDB files( i
see it in logs) Why does this can happen?

I'm referring to the limit attribute of the tempUsage element in
activemq.xml. A sample can be seen at
http://activemq.apache.org/xml-configuration.html. It's not well formatted
for easy reading, but it's correct XML.

out documentation and couldnt find anything for temp store.

If you set a limit of 0 for it with producer flow control enabled, no
messages will be written to it. I don't remember offhand whether it'll
still create the KahaDB files on disk in that case, but if that's something
you care about, it's a simple test for you to do.

Tim, is there a way to turn off temp store?

The temp store uses KahaDB even if the persistent store is configured to
use another database type, so I suspect that that's the source of those
KahaDB files.
