Subject AW: where does jackrabbit store it's data?
Date Tue, 19 Jan 2010 16:27:28 GMT
Thank you Thomas,

are there any recommendations on how to store the data?
If yes, why? What are the advantages of having a almost 100% database storage?
What are the advantages of storing anything into filesystem or why does it make sense to mix
it?

Regards, simon
