final class ChangeStream extends PipelineOperator

Low level pipeline operator which allows to open a tailable cursor against subsequent change events of a given collection.

For common use-cases, you might prefer to use the watch operator on a collection.

Note: the target mongo instance MUST be a replica-set (even in the case of a single node deployement).
