Flink Jira Bot updated FLINK-20912: ----------------------------------- Labels: auto-deprioritized-major auto-deprioritized-minor stale-major (was: auto-deprioritized-major auto-deprioritized-minor) I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help the community manage its development. I see this issues has been marked as Major but is unassigned and neither itself nor its Sub-Tasks have been updated for 60 days. I have gone ahead and added a "stale-major" to the issue". If this ticket is a Major, please either assign yourself or give an update. Afterwards, please remove the label or in 7 days the issue will be deprioritized. > Increase Log and Metric: Time consumed by Checkpoint Restore > ------------------------------------------------------------ > > Key: FLINK-20912 > URL: https://issues.apache.org/jira/browse/FLINK-20912 > Project: Flink > Issue Type: Improvement > Components: Runtime / Checkpointing, Runtime / State Backends > Affects Versions: 1.12.1, 1.13.0 > Reporter: fanrui > Priority: Major > Labels: auto-deprioritized-major, auto-deprioritized-minor, > stale-major > > In a production environment, some jobs with higher SLAs need to be restarted > quickly if failover occurs. Checkpoint restore is an important part of task > start. When the Flink task starts slowly, the related Log and Metric should > be added to facilitate troubleshooting. > For example: ByteDance shared in FFA 2020: They made OperatorState > parallelized restore. Without these metrics, there will be two problems: > 1. It is not easy to find the problem. If the task starts slowly, it is not > known whether the root cause is the slow Checkpoint restore. > 2. If optimized, how much speed has been improved for restore? Need to be > quantified. > I believe that many companies have made relevant metrics in their internal > Flink versions. -- This message was sent by Atlassian Jira (v8.20.1#820001)
