Thanks Nirmal and Udara.
Just found "minimum-autoscaler-rule.drl" at tests of autoscaler component.
It seems this rule([1]) is run against a partition. IMO we should run it
against a cluster since rules can be run in loops efficiently as follows,
rule "Minimum Rule"
dialect "mvel"
when
$deploymentPolicy : $cluster.getDeploymentPolicy()
$partitionGroup : PartitionGroup () from
$deploymentPolicy.getPartitionGroups()
$partition : Partition () from $partitionGroup.getPartitions()
eval($clusterContext.getMemberCount($partition.getId()) <
$partition.getPartitionMembersMin())
then
int memberCountToBeIncreased = 1 ;
if(AutoscalerRuleEvaluator.delegateSpawn($ctxt.getPartition()
,$clusterId)){
$ctxt.incrementCurrentMemberCount(memberCountToBeIncreased);
}
end
Thanks.
[1]
rule "Minimum Rule"
dialect "mvel"
when
$ctxt : PartitionContext ()
eval($ctxt.getCurrentMemberCount() < $ctxt.getMinimumMemberCount())
then
int memberCountToBeIncreased = 1 ;
if(AutoscalerRuleEvaluator.delegateSpawn($ctxt.getPartition()
,$clusterId)){
$ctxt.incrementCurrentMemberCount(memberCountToBeIncreased);
}
end
