Could you build this?
No Streaming PostgreSQL CDC data directly into Apache Iceberg tables while emulating the Postgres wire protocol requires deep database engine and distributed storage expertise.
What it would actually take: The architecture requires a custom storage engine and network server written in Rust, Go, or C++ implementing PostgreSQL wire protocol v3 and logical replication streaming (WAL decoding). It must manage Apache Iceberg metadata specifications—generating Parquet files, manifest lists, and atomic commit transactions on object storage like S3—while guaranteeing ACID semantics and handling schema evolution. This requires a dedicated team of distributed systems and database storage engine engineers.
Discussion
20 comments analyzed.
Competitors mentioned: Supabase ETL, Kuvasz-streamer, Sequin, DuckLake, SeaweedFS
Concerns raised: CDC reliability and flakiness with TOAST columns, WAL buildup risk when replication slots on primary, REPLICA IDENTITY FULL requirement for before/after values, Code quality concerns (vibe-coded), AI-generated responses from maintainer
Feature requests: Support for replication slots on replica instead of primary, Handle TOAST columns without REPLICA IDENTITY FULL by using object storage, MySQL/binlog support
