Describe the problem

The realtime client is decoding data from JSON (no support for binary data), how is the binary data encoded?

What about all other values like dates, big ints, etc?

Describe the improvement

Describe how the serialization is done, even better if you switch to a binary format for encoding data, something like msgpack maybe

Additional context

From what I can see it is encoded to a string that looks like the following:

\x30343036663238326632666330663030383739656463663365313.....

It looks like it's base 10 encoded
