ClickHouse Acquires PeerDB to Enhance Data Replication Capabilities

ClickHouse, the open-source real-time analytics database that emerged from Yandex in 2021, has announced its acquisition of PeerDB, a company specializing in cost-effective Postgres replication and change data capture. This strategic move aims to bolster ClickHouse's offerings, which already cater to a range of high-profile clients including Deutsche Bank, eBay, and Microsoft. While ClickHouse previously provided a Postgres connector, the integration of PeerDB promises significant speed enhancements and specialized features that were lacking in ClickHouse's existing toolkit. PeerDB's focus on creating a high-quality ETL tool for Postgres has positioned it as a leader in data replication, particularly for large datasets. The company’s technology facilitates the initial transfer of terabytes of data from Postgres to data warehouses like ClickHouse, while also ensuring synchronization through its change data capture system. This capability is crucial for businesses that rely on Postgres as their primary transactional database, as it allows for seamless analytics integration. ClickHouse co-founder Yury Izrailevsky highlighted the common trend among customers using Postgres for transactional applications and ClickHouse for analytics, emphasizing the need for expertise in managing change data capture. The acquisition will enable PeerDB to expand its capabilities to support additional data sources in the future, enhancing its value proposition. The financial details of the acquisition remain undisclosed, although PeerDB recently secured $3.6 million in seed funding. Izrailevsky expressed confidence that the agreed price reflects the contributions of the PeerDB team and their investors, marking a promising new chapter for both companies.
