We have a customized value of 5 retries. I don't know if it makes sense to have 16 retries. Shall we keep upper limit to 8?

Can't we retry as many times as the user specifies? (https://github.com/cortexproject/cortex/blob/master/pkg/querier/blocks_store_queryable.go#L542)

That's right. But I don't think we should recommend users to retry up to 16 times. I mean in general 3 to 7 retries make the most of sense. But maybe that's our usecase.
Do you have a usecase of using that many retries?

Oh, you're right. let's fix it.
