MongoChangeStream

Sync MongoDB collections via change streams into any database. Version 0.64.0, requires Redis (>=5.4.1) for state management and MongoDB driver (>=6.8.0). Provides initial scan with deterministic resumption and change stream event processing. Detects schema changes and emits events (e.g., 'schemaChange', 'processError'). Supports batch processing and configurable queue/scan options. Compared to alternatives, it is a lower-level library meant to be built upon, with companion libraries for MongoDB-to-MongoDB, Elasticsearch, and CrateDB sync. Uses debug for logging. ESM-only, ships TypeScript types.
