Stephan Ewen created FLINK-4256: ----------------------------------- Summary: Fine-grained recovery Key: FLINK-4256 URL: https://issues.apache.org/jira/browse/FLINK-4256 Project: Flink Issue Type: Improvement Components: JobManager Affects Versions: 1.1.0 Reporter: Stephan Ewen Assignee: Stephan Ewen Fix For: 1.2.0
When a task fails during execution, Flink currently resets the entire execution graph and triggers complete re-execution from the last completed checkpoint. This is more expensive than just re-executing the failed tasks. In many cases, more fine-grained recovery is possible. The full description and design is in the corresponding FLIP. https://cwiki.apache.org/confluence/display/FLINK/FLIP-1+%3A+Fine+Grained+Recovery+from+Task+Failures -- This message was sent by Atlassian JIRA (v6.3.4#6332)
