Module change_event 

MongoDB change-event classification and canonical Extended JSON rendering.

Change events stay as raw BSON from the driver until Arrow assembly decodes them once. Operation names are the server’s own operationType strings, so history records never use the engine’s _op changelog vocabulary.

Enums

ChangeOperation

Semantic class of a change-stream operationType.

Functions

canonical_document_extjson

Canonical Extended JSON v2 text for one raw document.

canonical_extjson

Canonical Extended JSON v2 text for one BSON value. Canonical form keeps every BSON type distinct (Int32 versus Int64, ObjectId versus string, Decimal128, dates).
