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.

Bridges PostgreSQL CDC events into Solid Queue-backed Active Job processors.

Mammoth Data Plane is the open-source PostgreSQL change-event delivery runtime in the Mammoth ecosystem. It realizes the CDC Ecosystem pgoutput and cdc-core libraries for PostgreSQL, then delivers normalized changes to webhook endpoints with durable checkpointing, retry state, dead letters, and operational visibility. Mammoth Data Plane is application-first: it can be installed as a Ruby gem, packaged into a container image, or deployed into Kubernetes with Helm.

pgoutput-source-adapter provides source adapters that normalize decoded PostgreSQL pgoutput events into downstream event models. The gem currently includes a CDC::Core adapter that transforms pgoutput decoder events into ChangeEvent and TransactionEnvelope primitives while preserving transaction and metadata context. This package forms the normalization boundary between the pgoutput family of gems and downstream change-event platforms.

Whodunit Chronicles records CDC change events as immutable ledger entries. It provides a tiny Chronicler processor, a Ledger abstraction, and simple ledger implementations without owning replication, runtime execution, or orchestration.
