----------------------------------
Summary: Improve Flink's ID system
Key: FLINK-15679
URL: https://issues.apache.org/jira/browse/FLINK-15679
Project: Flink
Issue Type: Improvement
Reporter: Yangze Guo
Fix For: 1.11.0
Flink uses a lot of IDs which are hard to decipher for the user:
- The string literal of most Flink’s IDs are meaningless hashcode. It does not
help the user to understand what happened.
- The LOGs do not contain the lineage info of those IDs. Currently, it’s
impossible to track the end to end lifecycle of an Execution or a Task.
- Some redundancy exists in Flink’s ID system, we need to sort out the current
ID system before introducing more complexity.
To help the user to understand what Flink is doing, we target to add more
meaning to Flink’s IDs and LOGs while cleaning up the redundancy and
refactoring the ID system.
This is an umbrella ticket to track all the relevant issues.
