How does replication affect kafka quota?

So by specifying a kafka quota for a user as 50 MBps, I can make sure it
can write on a partition at broker X (imagine this user has only 1
partition at this broker) at a max rate of 50 MBps. Now if the partition
has a replica on another broker Y, will the user still be able to write
data at rate 50MBps? Or will replicas slow down the user's write rate?


Thanks,
Archie

Thanks for the reply. I have few more questions regarding replication quota

a) Will replication quota be valid even when partitions do not move?
b) Can I apply replication quota for a particular client-id? If yes, how
can I do that?
c) Can I apply replication quota for a particular topic? If yes, how can I
do that?

Thanks,
Archie

Replication will not effect the users quota as it is done under a different replication quota (which you can control separately). The user should still see a 50 MBps maximum rate enforced into each broker.
