> When creating a partitioned region and then altering it by adding a parallel
> gateway sender, I have observed that, when sending transactions to the
> partitioned region, an event (GatewaySenderEvent) for each transaction is
> sent to every server hosting buckets for the partitioned region and not only
> to that/those hosting the bucket where the data in the transaction belongs.
> So, for example, in a partitioned region provided by two cache servers where
> redundancy is zero, when a transaction is sent, the put is done on the server
> hosting the bucket where the data in the transaction is to be stored but an
> event for the put is sent to the two members. This provokes in the server not
> hosting locally the bucket for the data in the event that the event
> (GatewaySenderEvent) is stored in the bucketToTempQueueMap member variable of
> the ParallelGatewaySenderQueue.
> Those events are eventually removed from that member as events are sent by
> the gateway sender to the remote site. Nevertheless, if the remote site
> cannot be reached, the events are kept in that member which could provoke a
> heap exhaustion problem if there is a sufficient amount of incoming
> transactions and the remote site cannot be reached for the required amount of
> time.
> Events for a transaction should only be sent to the servers hosting the
> bucket for the data in the transaction and not to all servers.
