Subject Default value for syncOnWrite for AMQ store should be true?
Date Thu, 04 Oct 2007 02:10:00 GMT
I have noticed that the default value for syncOnWrite for the AMQ store 
is set to false.

Is this a wise default?  As a user of a transactional messaging store, I 
would have thought the common expectation would be that if my broker 
dies, all messages in committed transactions have been safely written to 

The default behaviour of losing messages on a crash seems nasty to me.

I know this will have a detrimental impact on performance, but people 
can always set syncOnWrite to be false if need be, although I can't 
really imagine a situation where this would be useful?
