Re: [infinispan-dev] Hybrid locking scheme in ISPN 5.2.0
Thanks Galder,
I am reading again the documentation you linked and I am also running
some simple tests but I see this behaviour:
- with OPTIMISTIC mode the lock is acquired *only* at prepare time
(thus *not* like in ISPN 5.0);
- with PESSIMISTIC mode the lock is acquired at encounter time on the
primary node (again, thus *not* like in ISPN 5.0).
The behaviour I'm looking for is only-local encounter-time
locking + cluster-wide prepare-time locking.
Am I missing something?
Thanks again. Regards,
Diego
That's already possible, seehttps://docs.jboss.org/author/x/FAY5
Btw, the community wikis, like the one pointed below, are now used as design documents.
For the user guide, head tohttps://docs.jboss.org/author/display/ISPN.
Cheers,
