Copying pdx types via client
Does this functionality exist in the Native Client as well as the Java
Client?

It does support it and the PDX metadata would be correctly independent across both distributed systems. No issue of colliding PDX type IDs. It’s a much cleaner solution for that use case.

I may be mistaken, but I think that this feature attempts to address cases where users want to selectively copy several items from one distributed system to another. Not sure if the two separate implementations of "ClientCache" actually achieves the same thing. Would like to discuss though.

While the short answer is yes, Geode Native (GN) goes further in not requiring one to share clients across multiple distributed systems. You can create multiple independent caches in the same process space with GN. Each of these instances can be connected to independent distributed systems. The need to copy PDX metadata goes away. The need to create multiple pools to different systems goes away. All the pain and issues of supporting this “feature” just goes away. So if there is someone out there wanting to do what was done before I would strongly encourage to not and instead use independent caches.

Perhaps for others on this list that aren’t familiar with the context you could fill in the blanks.
It is assumed you are asking about the “feature” where PDX metadata is propagated from one connection pool to another in an attempt to support multiple distributed systems in the same client. While the short answer is yes, Geode Native (GN) goes further in not requiring one to share clients across multiple distributed systems. You can create multiple independent caches in the same process space with GN. Each of these instances can be connected to independent distributed systems. The need to copy PDX metadata goes away. The need to create multiple pools to different systems goes away. All the pain and issues of supporting this “feature” just goes away.

Okay, after a conversation here at the office with folks who know, I can
confirm the answer is "yes," NC has code to copy PDX types in the manner
you're asking after.
Thanks,
Blake

Hi Mike,
I'm not 100% certain what you're referring to, but... PdxSerializable in NC
has toData and fromData methods that allow you to copy objects via
serialization. That what you're looking for?
Thanks,
Blake
