How to navigate difference between C++/Java versions

[balayanv]

After using SBE and Chronicle Wire for years i finally have opportunity to use this in anger on a real project.

Is there somwhere i can have a good understnading of what is missing in java version that is so actively being commited in cpp and rust versions...

I'm mostly only interested in data part of it and none of the RPC... i assume defining messages in java version will be fully compatible with cpp and rust?

Is shared memory between java and other langs implemented?

capnproto-java does not have:

• canonicalization
• dynamic reflection

• AnyStruct and similar types (these fall back to AnyPointer).

  In general, capnproto-java is a lot less polished than capnproto-c++ and capnproto-rust, but it should get the job done if you just need basic serialization.

Yes, the serialization format has been stable since 2013.

No.
