Reindex is too slow in repos with thousands of charts about helm-s3 HOT 3 OPEN

We have actually, but that itself is a challenge. Each delete (like upload) takes a considerable amount of time and probably 99% of the references need to be cleaned. The criteria I can think of is remove any charts over {time period old} then also consider an allow list of currently used chart-versions that are in use. I thought about it a while and forking s3 is probably the easiest way for us to fine tune reindex to have a prune option to apply that criteria.

Wow that's a real number. I agree that the plugin was never designed to handle such volumes, and there is definitely a room for improvement.

Out of curiosity, why do you have so many charts? Have you considered cleaning up i.e. removing unused versions?
