Explanation

The Change Feed Processor in Azure Cosmos DB consists of four distinct components mapped to specific roles: the Monitored Container is the source container being watched for changes, the Lease Container stores state/checkpoints to coordinate processing across multiple instances, the Host is the compute instance (processor instance) that runs the change feed processor and manages distribution of work, and the Delegate is the user-defined function/code that contains the business logic to handle the detected changes. Each component serves a unique, non-interchangeable purpose in the pipeline, from source tracking through to custom processing logic.
