Hi guys,
What do you think about org.apache.camel.spi.RoutePolicy implementation that
uses hazelcast to support distributed locking/unloking?
Such a route policy will force the route to run only on a single node in the
cluster. Moreover there can be two route policies:
# the first one will create a distributed lock on every incoming exchange and
will release the lock when exchange processing completes. This policy will
allow to process exchange only on a single node of the cluster at a given time.
When exchange processing completes the second node in the cluster will be able
to obtain a lock.
# the second route policy will create a distributed lock on route startup, and
will release the lock on route shutdown, so the route will run only on a single
node in the cluster all the time.
