ryan-brosas DuckDB: vectorized execution core (vector formats, expression executor, adaptive filters)
Foundation contract
This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.
Provenance and revision
- Source record:
duckdb-vectorized; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index. - Recorded revision:
main@044a04a7cd39e6e8235f756597ae42dde084e5e5. - Full provenance, coverage caveats, boundaries, and preserved evidence:
references/index.md.
Topic map
- Representative topics: Unified read format (Orrify); Tuple indirection; Zero-copy algebra; Format matrix; Constant folding; CASE funnel; Conjunction funnel; Adaptive filter order.
- Scope and retrieval questions:
references/index.md#use-this-for. - Complete capsule chooser:
references/index.md#load-the-matching-source-dump. - Detailed grouped map:
references/index.md#capsule-map. - Source limitations and portability boundaries:
references/index.md#boundaries.
Retrieval
Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
