Subject kahadb system property configuration options
Date Thu, 27 Jun 2013 16:27:48 GMT
Hi,

I came across the following system properties that are uses by the
kahaDBPersistenceAdapter, their default values are:

-Dorg.apache.kahadb.journal.appender.WRITE_STAT_WINDOW=0
-Dorg.apache.kahadb.journal.CALLER_BUFFER_APPENDER=false

A particular unit test recommends setting them to:

-Dorg.apache.kahadb.journal.appender.WRITE_STAT_WINDOW=10000
-Dorg.apache.kahadb.journal.CALLER_BUFFER_APPENDER=true

Are these type of values recommended for when one is dealing with
persistent messages backed by slow storage?

If not, can someone provide recommended scenarios when these values should
be adjusted (per the unit test example above)?

Thanks,
Paul
