I'm having problem consuming data which are compressed using zstd (#619):

10:57:51.651 [error] Consumer my-app-consumer terminate reason: {"failed to decompress: ZSTD_CONTENTSIZE_UNKNOWN",

    ]},

   {:gen_server, :handle_msg, 6, [file: ~c"gen_server.erl", line: 2261]}
 ]}

I'm not the producer of this data so I can't give insight about that but if I consume the same topic using Java SDK, it works. I need to dig further to provide more details.

I'm planning to see if I use brod to produce data using zstd, can I consume it or not. Also planning to extract to read the raw binary data from this topic and try to decompress it manually.

I'm using

ezstd -> 1.2
brod -> 4.4
Erlang/OTP -> 27
