Oodle is a fully managed, serverless metrics observability platform. It is a drop-in replacement for Prometheus that delivers fast performance at high scale. Oodle is 3x cheaper than Managed Prometheus and 10x cheaper than other commercial vendors.
Serverless helps with query performance. Queries can be parallelized with serverless functions, this especially helps with long range queries. As an added advantage, compute does not have to be pre-provisioned for queries.
