Wallaby – Postgres CDC Engine for .NET

Wallaby, a new Postgres change data capture (CDC) engine for .NET, lets developers point at EF Core entities, Marten documents or plain tables to stream materialized changes with compile-time errors as the model changes. The tool transforms and enriches changes using existing EF, Marten, Dapper or raw Npgsql tooling, delivers them to pluggable sinks such as search indexes, vector databases or plain HTTP endpoints with at-least-once delivery, and runs versioned backfills automatically when output shape changes.

Point at your EF Core entities, Marten documents or plain tables and get up & running with minimal effort. Get compile-time errors as your model changes.

Transform + Enrich

Convert, enhance & flatten materialized changes into the required shape for your output destination. Use your existing EF & Marten tooling, or Dapper and raw Npgsql on plain tables.

Pluggable Sinks

Ship your transformed data to anywhere it needs to go, be it a search index, vector DB or just a plain HTTP endpoint. At-least-once delivery ensures your data never goes missing.

Versioned Backfilling

Automatically run backfill operations as output shape is changed. Ensure your destination is always up to date.
