Hi all,
Why does ClusteredGetResponseValidityFilter maintain a list of
pendingResponders? Wouldn't it be more efficient if
needMoreResponses() returned as soon as one positive response has
been received regardless of who's pending to return anything? I'm
assuming here that SuccessfulResponse means that the clustered get
returned what we're trying to get.
IIRC this was an issue where if we hadn't seen any valid responses,
JGroups would timeout. So needMoreReponses() needed to return true at
some point, and in this case that point is if we don't have a valid
response AND there are more pending responders.
This may not be the case anymore with JGroups 2.8 though.
I implemented a very similar thing for HAJNDI in such way that as
soon as a look up had succeed, we wouldn't wait for anyone else.
Cheers,
