Yun Tang updated FLINK-13418: ----------------------------- Summary: Avoid InfluxdbReporter to report unnecessary tags (was: Avoid InfluxdbReporter to report uncessray tags) > Avoid InfluxdbReporter to report unnecessary tags > ------------------------------------------------- > > Key: FLINK-13418 > URL: https://issues.apache.org/jira/browse/FLINK-13418 > Project: Flink > Issue Type: Improvement > Components: Runtime / Metrics > Reporter: Yun Tang > Priority: Major > Fix For: 1.10.0 > > > Currently, when building measurement info within {{InfluxdbReporter}}, it > would involve all variables as tags (please see code > [here|https://github.com/apache/flink/blob/d57741cef9d4773cc487418baa961254d0d47524/flink-metrics/flink-metrics-influxdb/src/main/java/org/apache/flink/metrics/influxdb/MeasurementInfoProvider.java#L54]). > However, user could adjust their own scope format to abort unnecessary > scope, while {{InfluxdbReporter}} could report all the scopes as tags to > InfluxDB. > This is due to current {{MetricGroup}} lacks of any method to get necessary > scopes but only {{#getScopeComponents()}} or {{#getAllVariables()}}. In other > words, InfluxDB need tag-key and tag-value to compose as its tags while we > could only get all variables (without any filter acdording to scope format) > or only scopeComponents (could be treated as tag-value). I think that's why > previous implementation have to report all tags. > From our experience on InfluxDB, as the size of tags contribute to the > overall series in InfluxDB, it would never be a good idea to contain too many > tags, not to mention the [default value of series per > database|https://docs.influxdata.com/influxdb/v1.7/troubleshooting/errors/#error-max-series-per-database-exceeded] > is only one million. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
