> Currently, we use lz4 for shuffle data compression which is a good balance
> between IO optimization and CPU consumption. But for some scenarios, the IO
> becomes bottleneck and the storage space is limited (especially for k8s
> environment). For these cases, we need compression algorithms of higher
> compression ratio to further reduce IO.
