Do you have thoughts on this? I suggest that `EventProcessorThread` can leverage `GrowableBufferSupplier` to reuse buffer as much as possible. Additionally, `Group#computeTopicHashin` should use `ByteBufferOutputStream` to generate the bytes array, as `ByteBufferOutputStream#buffer#array` can avoid extra array copy like `ByteArrayOutputStream#toByteArray` -- This is an automated message from the Apache Git Service.
