Logical decoding was introduced in PostgreSQL 9.4 and has been constantly improved. The extensible mechanism of output plugins and in-core logical replication based on logical decoding have enabled many new applications. One popular use case of this feature is implementing the Change Data Capture (CDC) pattern.

In this talk, I’ll share challenges faced by Zalando’s DBaaS team while adopting and maintaining a high-throughput CDC solution, a replacement of the old-good PgQ approach. I will focus on what PostgreSQL logical decoding feature is missing to make its application easier and more reliable.

Join this session to discuss real-world pain points and ideas for evolving PostgreSQL logical decoding workloads at scale.
