Kuvasz-streamer is an open source CDC project for Postgres, tightly integrated with Postgres Logical Replication for high performance and low latency. It is lightweight, written in Go, and can run in a declarative mode with configuration stored in a YAML file. It supports an interactive web interface for real-time configuration changes. Benchmarked at 10K tps with less than 1 second latency, Kuvasz-streamer uses Postgres protocols for sync and replication, with global rate-limiting to prevent server overload. It manages publications, replication slots, and offers flexible table propagation models. It can be used for data consolidation, database upgrades, and performance optimization.
