There's no shortage of physical replication solutions for PostgreSQL, they scale horizontally and provide high read availability. But where they fall short is write availability, which leads many users to consider PostgreSQL logical replication. Existing solutions have a single point of failure or are dependent on a forked, vendor-provided PostgreSQL extension making reliable, enterprise-class logical replication hard to come by. Furthermore, these solutions put limits on scaling PostgreSQL.

By combining Kafka, an open source event streaming system with PostgreSQL, customers can get a fault tolerant, scalable logical replication service. Learn how EDB Replicate leverages Kafka for high write availability needed for today's demanding consumers who expect their applications to be always available and won't tolerate latency.
