Do you mind a quick rebase? We just fixed CI (it guides users on some required formatting e.g. your file name should follow 0056-xyz.md) |
This proposal introduces extension points for TSDB index lookups that allow different execution strategies to address the problem of inefficient index lookup usage. Key features: - Extension points via LookupPlanner and LookupPlan interfaces - Simple rule-based implementation example (ScanEmptyMatchersLookupPlanner) - Enables downstream projects like Mimir, Thanos, and Cortex to implement custom optimization approaches - Builds on scan matchers foundation from PR #16835 The proposal focuses on providing interfaces rather than prescribing specific optimization strategies, allowing flexibility for different deployment scenarios and use cases.
