Bloomberg, a leading data provider for financial markets, leverages ClickHouse to optimize data ingestion and analysis capabilities. The company's unique challenge is to provide accurate and timely information to institutional investors while managing large datasets. ClickHouse's columnar storage, ease of use, and ability to write complex calculations with simple mathematics make it an excellent choice for Bloomberg's use case. By optimizing data ingestion rather than query speed, the team has efficiently ingested vast amounts of data while ensuring data quality. The company's approach to using buffer tables, creating new tables for changes, and testing disaster recovery simulations demonstrates the flexibility and reliability of ClickHouse in supporting their specific requirements.
