Jul 28Improved database performance by filtering raw contract IDs to enable Parquet partition pruning. This optimization speeds up contract detail queries.wegovnyc/databook-private ↗Jul 28Added a New York Department of State legal-entity card to vendor profiles, displaying business age, legal form, and registration details. The integration uses an offline DuckDB-to-Postgres crosswalk script to match vendors with the NY DOS registry, achieving a 43% unambiguous match rate.wegovnyc/databook-private ↗Jul 28Added the Doing Business Database (LL34) to vendor profiles, linking 4,474 vendors to over 31,000 associated people and registered lobbyists. This update integrates a new daily ingestion script, implements conservative name-matching to prevent false positives, and resolves source data issues like truncated dates.wegovnyc/databook-private ↗Jul 28Optimized the contract detail endpoint by filtering on the raw contract_id column instead of using a regex function, enabling Parquet row-group pruning. The change also materializes filtered rows once to avoid duplicate scans, resulting in up to a 34x speedup for contract queries.wegovnyc/databook-private ↗Jul 27This update enables five PASSPort vendor sub-tables to load and refresh daily via a new post-ingest hook. It surfaces new vendor profile sections for ownership, leadership, and performance ratings, while adding contract-specific MOCS ratings. It also fixes a bug where post-ingest hooks were silently skipped during extractor dataset processing.wegovnyc/databook-private ↗Jul 27Surfaces existing database and API data on vendor and contract profiles. Key additions include SBS certified-business profiles matched by normalized name, Checkbook paid-to-date actuals, contract payment windows, and current contract value tiles. It also links transaction payees to PASSPort IDs and improves labelling for NYCHA and transaction blocks.wegovnyc/databook-private ↗
