Hi
Hi Radev,
Thanks for the information. It seems interesting.
IMO, Arrow has much to do for data compression. However, it seems there are
some differences for memory data compression and external storage data
compression.
Could you please provide some reference for stream splitting?
Best,
Liya Fan
