Do you have persistent storage on your Thanos Store pods (I assume k8s here)? The RAM usage probably comes from building binary index headers. Maybe there is some opportunity here...

Now that I think about this more, I would love to see this implemented as sparse files https://en.m.wikipedia.org/wiki/Sparse_file instead of shoehorning everything into k/v storage systems because they aren't as...

Ran this test quite a few times locally and cannot reproduce :/

What about `${HTTP_IP}:${HTTP_PORT}/debug/pprof/goroutine?debug=1` of Rule when this happens? Could you please upload it? I'm still not sure what happened here.
