[infinispan-dev] Time for a new NBST thread

Hi guys I published a new version of the non-blocking state transfer design document here: https://community.jboss.org/wiki/Non-blockingStateTransfer This time I focused a bit on the "other" cache configuration (other than dist-sync, that is). This revealed some new problems, these are the most interesting ones: * With async-commit phase or async-1pc, we can get stale locks on joiners. I have an Infinispan-only approach that should work, but it may be easier to just require FLUSH. * Async-commit + recovery enabled: a node sends a commit command to 2 owners, one node loses the message, and then the originator dies before retransmitting. How do we let the TM know that the transaction is in-doubt, since to the TM it looks like it has been committed? Please try to read the document and let me know if anything sounds too opaque or doesn't make sense. I think it's good enough for starting the implementation, although I've removed the actual implementation details from the document for now. Cheers Dan
