Returns a builder object that offers a step-by-step fluent API to build a custom MongoDB BatchSource for the Pipeline API.

Here's an example that builds a simple source which queries all the documents in a collection and emits the items as a string by transforming each item to json.

Parameters:

name - a descriptive name for the source (diagnostic purposes)

clientSupplier - a function that creates MongoDB client

Returns a builder object that offers a step-by-step fluent API to build a custom MongoDB StreamSource for the Pipeline API.

The created source will not be distributed, a single processor instance will be created on an arbitrary member. The source provides native timestamps using ChangeStreamDocument.getClusterTime() and fault tolerance using ChangeStreamDocument.getResumeToken().

Parameters:

name - a descriptive name for the source (diagnostic purposes)

clientSupplier - a function that creates MongoDB client

stream
