Pavel Tupitsyn updated IGNITE-25441:
------------------------------------
Description:
Currently, we allocate response Netty buffers in *ClientInboundMessageHandler*
too early - even before the processing has started. As a result, the buffer is
out there doing nothing while a potentially long-running async operation is
being processed. In case of many clients and many active requests, we'll have a
lot of buffers allocated for no reason.
Additionally, it is not always possible to ensure buffer release. Some
operations may never complete due to bugs, node restarts, etc, causing buffer
leaks.
