QueryFuser is a PostgreSQL-compatible proxy for BigQuery that cuts your query costs. When BI tools like Looker or Tableau load a dashboard, they fire separate queries per tile — each scanning the same tables. QueryFuser intercepts these, merges concurrent queries hitting the same tables into a single BigQuery scan, and splits the results back. Combined with cache optimization that rewrites volatile SQL expressions for better cache hits. Zero code changes — just lower bills.
