@zhijiangW Yes, let's discuss this when the feature is complete.
Our thinking so far is:
- One can specify an absolute amount of network memory (similar as one
can specify an absolute amount of managed memory for batch)
- If no absolute amount is specified, a relative fraction of the JVM heap
will be pre-allocated as network buffers.
