parity

Overview ¶

Parity compare tool: field-by-field comparison of Go ETL output against the pre-cutover rows written by the legacy Python indexer.

This tool was used to validate the production cutover from the legacy Python celery indexer to the Go ETL (now complete — the Go ETL is the production indexer). It remains useful for auditing the Go ETL against a snapshot of historical data.

Usage:

go run ./pkg/etl/parity --db "$ETL_DB_URL" --prod-db "$PROD_DB_URL"
