okay, and one last question, is there a bit more documentation on the following, so we can know what to expect, and the implementation is quite sound, working as designed and no known issues with the following?
<ul> <li>default: the first is used while possible and others datasources are just backup, this is typically the failover case</li> <li>random: any datasource of the list is used</li> <li>reverse: between two call to a method the list is reversed</li> <li>round-robin[%N]: round robin between datasources, you can specify how many step you browse between two calls using N (default is 1)</li> </ul> i saw the limitations on the referenced pages (dynamic datasources), but I didn't see any known issues in your/Romain's post/blog. please excuse my ignorance, if I have not heard or seen much chatter about this on the mail list. I usually try to pay attention to almost all tomee emails, especially those that interest me the most. :) On Sun, Nov 3, 2013 at 10:22 AM, Romain Manni-Bucau <[email protected]>wrote: > If you dont use it then thats ok.
