Description
Is your feature request related to a problem? Please describe.
Thanos supports something called time based partitioning https://thanos.io/tip/components/store.md/#time-based-partitioning on Store Gateway. This is a good way to do hot/cold data tiering as relatively recent data (within 1 month) in store gateway is accessed much more often than older data (older than 1 month).
Time partitioned store gateways can configure different replication factors and other configurations, which helps to reduce SG memory consumption. (Can use a larger replication factor for hot data and smaller RF for cold data).
Describe the solution you'd like
There are multiple ways to do this but both requires some non trivial code changes.
- Querier supports multiple Store Gateway Ring and routes requests accordingly
- Querier still uses one SG ring, but X% of SGs in the ring are hot SGs and other SGs are cold SGs. Tiered SGs are basically two subrings and blocks will be assigned to the subrings based on the time range and block ID hash.
