Querier: Support Full Parquet Storage Mode #6888
Description
Is your feature request related to a problem? Please describe.
Today if parquet queryable is enabled in Querier, Querier still has the fallback logic. If a block is available in Parquet format then it tries to query Parquet and otherwise it queries Store Gateway for TSDB blocks.
We should try to support a mode which disables the fallback logic and only queries Parquet files so that users can fully eliminated store gateways.
Describe the solution you'd like
For the non fallback mode, If parquet files are not available, we can throw some warning or fail the request similar to consistency check failure.
