-----------------------------------
Summary: New latency tracking metrics format causes metrics
cardinality explosion
Key: FLINK-10484
URL: https://issues.apache.org/jira/browse/FLINK-10484
Project: Flink
Issue Type: Bug
Components: Metrics
Affects Versions: 1.5.4, 1.6.1, 1.6.0
Reporter: Jamie Grier
Assignee: Jamie Grier
The new metrics format for latency tracking causes huge metrics cardinality
explosion due to the format and the fact that there is a metric reported for a
every combination of source subtask index and operator subtask index. Yikes!
This format is actually responsible for basically taking down our metrics
system due to DDOSing our metrics servers (at Lyft).
