Is your proposal related to a problem?

Query frontend can split queries horizontally (by time range) using fixed intervals only. For example, If the split interval is set to 24h, queries for the past day will not be sharded horizontally.

Describe the solution you'd like

I would like to have a mechanism to make horizontal sharding more dynamic, so that the number of shards can be determined by the query time range.

An example solution would be to introduce min-horizontal-shards and min-split-interval parameters so that queries shorter than the split interval but longer than min-split-interval would also be sharded in min-horizontal-shards queries.
