-------------------------------
Summary: Remove CHARACTER_FILTER.filterCharacters function when
notify dimension values.
Key: FLINK-37020
URL: https://issues.apache.org/jira/browse/FLINK-37020
Project: Flink
Issue Type: New Feature
Components: Runtime / Metrics
Affects Versions: FLINK-25874
Reporter: hiliuxg
Fix For: FLINK-25874
remove the CHARACTER_FILTER.filterCharacters function when notify dimension
values.
The CHARACTER_FILTER.filterCharacters was added because Prometheus gateway does
not support invalid characters in metric names. However, for metric values, the
Prometheus gateway does not have such restrictions.
Refer to the documentation:
https://prometheus.io/docs/instrumenting/writing_exporters.
Therefore, removing this functionality will have no impact and will also
support Chinese characters in metric values, making it easier to filter metric
values with Chinese characters.
