If all you need is want to execute certain code on a particular node (i.e. no actual cache entry need to be created), you can use invocation service.1 person found this helpful
You can give the node a special rolename or member name. Then you can just pick that node to run the invocable.
I was reading about the InvocationService and it seems that I cannot use it in the standard version of oracle coherence.
So, do you think that it worth upgrading to enterprise edition only for this subject?
Thx in advance,
Enterprise/Grid edition do have better performance than standard edition, especially if you run query/aggregation against huge entries.1 person found this helpful
But IMHO, it's not worth it if you only need the Invocation service unless you want to use Coherence as a compute grid like use case.
