Hello thammoud,
Try to use affinity feature for cache. For given accountId all
PIDDetails better place in one node.
Example:
cacheCfg.setAffinityMapper(new AffinityKeyMapper() {
@Override public Object affinityKey(Object key) {
if (keyinstanceof PIDDetails){
PIDDetails det = (PIDDetails)key;
return det.getAccountId();
}
return key;
}
@Override public void reset() {
}
});
