cdc-concurrent provides optional Async-backed I/O-concurrent execution for cdc-core. It accelerates I/O-bound PostgreSQL Change Data Capture (CDC) event processing while preserving the cdc-core programming model.

cdc-parallel provides optional Ractor-backed parallel execution for cdc-core. It accelerates PostgreSQL Change Data Capture (CDC) event processing while preserving the cdc-core programming model.

Adds CDC-aware processor jobs and runtime selection to Sidekiq, allowing selected jobs to execute payloads directly, through cdc-parallel, or through cdc-concurrent.
