Agentic BigQuery Discovery
Jordan Totten
Apache-2.0 evaluation harness for the table-retrieval stage before NL2SQL. It compares six BigQuery and Dataplex discovery strategies across a 15-table corpus, 25 graded questions and five repetitions, with Vertex AI Pipelines, checkpointing, scoring and committed full-run results.
Verified 2026-09-22. Repository includes source, Apache-2.0 license, 347 hermetic tests, a 25-question graded corpus, a Vertex AI Pipelines runner and a committed 3,000-cell result audit. Important caveat: the first complete run invalidates its own enrichment-tier comparison because Dataplex index warm-up correlated with tier order. The approach comparison, reranker precision result, latency and token measurements remain usable according to the project audit. No tagged release; 0 stars/0 forks at verification.
