What our customers are saying
We are having an amazing experience using the Postgres CDC connector in ClickPipes. We seamlessly moved our 30TB Aurora database to ClickHouse Cloud and are continuously keeping it in sync. We did not expect any ETL tool to handle our load, especially after a bitter experience in the past. However, we were pleasantly surprised by how reliable and performant ClickPipes has been for us.
We already reduced our Postgres to ClickHouse snapshot times from 10+ hours down to 15 minutes with PeerDB. Combining ClickHouse’s powerful analytics natively with PeerDB’s real-time data capture capabilities will greatly simplify our data processing workflows. This integration will enable us to build analytical applications faster, giving us a competitive edge in the market.
