Change Details

For example, we have added segmentation dimensions in metrics like, ``` - path: "{_metric}.byWiki.{wiki}" + path: "{_metric}.byEditCount.{edit_count_bucket}.byWiki.{wiki}" ``` If the "byWiki" metric is left in place but no longer updated, it has potential to confuse us. We should delete all data under these outdated paths. TBD: list all deprecated metrics.

We should delete all data under these outdated paths. When it's possible to backfill data into the new structure, we should do so at least until the beginning of our baseline window. Let's say 2021-01-01. If backfilling is impossible, maybe we should archive the old data so that we don't destroy baseline data. TBD: list all deprecated metrics.
