It becomes production ready since 1.9 (FLINK-4256). State restore is also supported since then. There is no plan to backport the changes to 1.8 since the changes are huge and not bug fixes. was (Author: zhuzh): Hi [~andrew_lin], RestartPipelinedRegionStrategy is experimental in 1.8 with some known issues.
