Ismael Juma commented on KAFKA-13089:
-------------------------------------
The BufferSupplier implementations we have are not thread-safe and work best in
a thread-confined way. Can each listener hold a thread confined buffer supplier?

> The latest KafkaRaftClient creates a new BufferSupplier every time it is
> needed. A buffer supplier is needed when reading from the log and when
> reading from a snapshot.
> It would be good to investigate if there is a performance and memory usage
> advantage of sharing the buffer supplier between those use cases and every
> time the log or snapshot are read.
> If BufferSupplier is share, it is very likely that the implementation will
> have to be thread-safe because we need support multiple Listeners and each
> Listener would be using a different thread.
