The agent patch implements the core performance intent: it replaces hot-path linear scans with map-based O(1) lookups (`configuration_visitor`, `datasource_configuration`), adds cached interface-implementor/entity computations (`abstract_selection_rewriter`), precomputes datasource membership checks (`datasource_filter_collect_nodes_visitor`), and introduces secondary-run skipping for already-processed fields to avoid reprocessing the full tree. The approach differs from gold but matches the requested behavioral improvements.
Code Review
The patch likely satisfies the intended planner performance improvements, but it introduces a notable concurrency hazard in datasource metadata index initialization that should be fixed before relying on it in concurrent execution paths.
The `prepareIndexes` fast-path reads `indexesReady` outside synchronization while other goroutines may set it under lock. This is a classic unsynchronized read/write race in Go; use `sync.Once`, always lock before checking, or atomics for the flag.
