Distributed Lock Service [closed]

by

A newer kid on the block is hazelcast. I’ve been playing with it and it is amazingly simple to use and configure.

As far as I can see there shouldn’t be any conflict between Gigaspaces and hazelcast as hazelcast doesn’t have any dependencies i.e. no jgroups.jar etc

Hazelcast:

  1. A mutual exclusion (lock), yep implementation of java.util.concurrency.locks.Lock
  2. Automatic lock release after a certain timeout, yep all locks are released if a member leaves the cluster
  3. Java implementation, yep
  4. Nice to have: .Net implementation, nope is a pure java solution, might be possible to port to j#
  5. If it’s free: Deadlock detection / mitigation, nope no effort is made my Hazelcast to handle this
  6. Easy deployment, it’s a single jar with a single config file, deployed as part of your application, no additional processes are required
