Hi Steve,
Well, you can technically use more than just the key in your partition
resolver. You can also use a callback argument, something like the below
code. This would put all of your data into bucket 0. The issue is that all
operations will have to pass the callback argument, so if you need to do a
get you will also need to pass a callback argument to do a get from the
correct bucket.
int callbackArgument = 0;
region.putAll(hashmap_with_your_data, callbackArgument)
class MyPartitionResolver implements PartitionResolver {
Object getRoutingObject(EntryOperation<K, V> opDetails) {
return opDetails.getCallbackArgument().
}
}
