Hi Gauri,
I'll take a stab at your questions (others will undoubtedly correct me if
I'm wrong).

Kafka does work over TCP (what else :)
No format expectations (binary).
End to end latency depends on various parameters, like network, memory, but
it is (if you consume straight away; i.e. no consumer lag; i.e. lag can fit
in the OS page cache so you're not even hitting disk when consuming)
measured in low 10s of ms.
No read replicas. You only read from partition's master. I.e. replicas are
used to achieve redundancy.
