-----------------------------------
Summary: Introduce new compression algorithms of higher
compression ratio
Key: FLINK-28382
URL: https://issues.apache.org/jira/browse/FLINK-28382
Project: Flink
Issue Type: Bug
Components: Runtime / Network
Reporter: Yingjie Cao
Fix For: 1.16.0
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.
