MongoDB Delete

MongoDB Delete

Certified

Delete documents from MongoDB

Runs deleteOne (default) or deleteMany on a collection. Filter supports BSON strings or maps rendered from Flow variables.

Failures

DELETE_MANY is not atomic: if it fails mid-write, some documents may already be deleted and the task reports no count. A retry with the same filter deletes the rest. Retry a DELETE_ONE only when its filter matches a single document, such as on _id.

Assets this task consumes as inputs or produces as outputs, for lineage tracking and the asset graph (Enterprise Edition). A flow declaring this property on a task is rejected in the open-source edition.

Possible Values

Asset failure behavior

Behavior applied to the task state when a declared asset fails to render, emit, or be persisted (e.g. a lock conflict): FAIL escalates it to FAILED, WARN (default) warns it if it would otherwise succeed, IGNORE leaves the state untouched.

enableAutobooleanstring

Whether to auto-register assets referenced dynamically at runtime that are not statically declared in inputs or outputs.

Query filter

BSON string or map rendered before execution. Required with DELETE_MANY: an empty map filter fails, set filter: '{}' (string) to delete every document in the collection. A null map entry is dropped when the flow is parsed; pass a JSON string when a null is needed, for example '{"deletedAt": null}'.

Possible Values
DELETE_ONEDELETE_MANY

Delete operation

DELETE_ONE (default) or DELETE_MANY.

Documents deleted

Null for unacknowledged writes (w=0), which have no counts to report.

Whether the write was acknowledged

Unitcount

Number of documents deleted from the MongoDB collection
