There is nothing that we use from the oversampling feature today, and the move to Prometheus removes most of the need for it since we no longer "need" to have large amounts of data every single minute in order to have meaninful aggregates (in Prometheus we can summarise buckets over larger time spans instead).
There's a couple of things to be done here:
- Remove JavaScript code in the MediaWiki-NavigationTiming extension for oversampling.
- Remove config and package file export for oversampling in MediaWiki-NavigationTiming extension.
- Remove unused NavigationTiming config values in wmf-config.
- Make sure we use the same sample rates for NavigationTiming in wmf-config for all wikis.
Keep the schema as is for now, so if we need it in the future, it easy to add back.
