Subject Re: REST: support getting objects from cache.
Date Mon, 26 Feb 2018 07:00:15 GMT
Hi Alexey,

1) IMO for this task you should ALWAYS work in binary mode.
What is the use case for deserializing with a real class and then
serializing to JSON?
Looks like a waste of resources to me.

2) This should not be the case, please re-check your code.
Binary meta preserves original case (stores field names as is), just
checked this with 2.4 build.

3) JSON serializers typically handle this by adding special fields ($id and
$ref in Json.NET, for example).
But I believe this is a rare use case and can be skipped in initial
implementation.

Thanks,
Pavel
