> This is a followup jira from KAFKA-3894.
> We can potentially make the allocation of the dedup buffer more dynamic. We 
> can start with something small like 100MB. If needed, we can grow the dedup 
> buffer up to the configured size. This will allow us to set a larger default 
> dedup buffer size (say 1GB). If there are not lots of keys, the broker won't 
> be using that much memory. This will allow the default configuration to 
> accommodate more keys.
