The message size limit is imposed to protect the brokers and consumers from
running out of memory. The consumer does not have support for streaming a
message and has to allocate memory to be able to read the largest message.
You could try compressing the files but I'm not sure if that will get you
as much space saving to make it feasible for Kafka usage.
