Subject Re: Basic questions about producer control flow
Date Tue, 10 Dec 2013 09:07:21 GMT
Documentation is confusing for me
I'm reading your post

http://www.christianposta.com/blog/?p=273

and I've got some questions

****If PCF is disabled ( producerControlFlow = false ) **** :

- do systemUsage limits matter ? is PCF the only componet which uses
these limits ?
- are these systemUsage limits also used by Store based cursors to
choose what messages go to disk?
- what happen if systemUsage limits are exceeded ? is the underlying
connection blocked ?


Thanks and regards
