Take a look at the Javadoc: http://labs.jboss.com/file-access/default/members/jbosscache/freezone/doc... If you want a flush every minute, and no more, then set batchSize to a very high value, then pollWait to one minute (in milliseconds.) My recommendation would be to flush every 1-5 seconds at most, and set the batch size to a reasonable value (such as 100). This is so that one DB operation is not too long.
