Prepares a builder for watching the change stream of this collection.
Prepares a builder for watching the change stream of this collection.
Note: The target mongo instance MUST be a replica-set (even in the case of a single node deployement).

def events(coll: BSONCollection)(
  implicit ec: ExecutionContext): Cursor[BSONDocument] =
  coll.watch[BSONDocument]().cursor
```
T
the type into which Change Events are deserialized
resumeAfter
The id of the last known Change Event, if any. The stream will resume just after that event.
startAtOperationTime
The operation time before which all Change Events are known. Must be in the time range of the oplog. (since MongoDB 4.0)
pipeline
The sequence of aggregation stages to apply on events in the stream (see MongoDB documentation for a list of valid stages for a change stream).
maxAwaitTimeMS
The maximum amount of time in milliseconds the server waits for new data changes before returning an empty batch. In practice, this parameter controls the duration of the long-polling behavior of the cursor.
fullDocumentStrategy
if set to UpdateLookup, every update change event will be joined with the current version of the relevant document.
reader
the reader of the resulting change events

Since
MongoDB 3.6
