zhuzhurk edited a comment on issue #9688: [FLINK-13056] [runtime] Introduce FastRestartPipelinedRegionStrategy which has better failover handling performance at the cost of slower region building and more memory used URL: https://github.com/apache/flink/pull/9688#issuecomment-532262379 > How do you configure the `FastRestartPipelinedRegionStrategy`? One option is a boolean config "jobmanager.execution.failover-strategy.region.fast-mode". This reveals to users that we have a fast mode for region failover. Another option is a new supported value "region-fast" for the failover strategy specification config ("jobmanager.execution.failover-strategy"). This reveals to users a new region failover strategy. I prefer the first option which hides the implementation and makes it easy if later we'd like to keep only one region failover strategy. What's your opinion? I planned to add the config when using it for the legacy failover strategy creation. But as you mentioned we can also add it in this PR.
