Description:
An array of aggregation pipelines to run in your change stream. You must configure this setting for the change stream event document, not the fullDocument field.

flujo de cambios.full.documento | Type: string
Description:
Determines what values your change stream returns on update operations.
The default setting returns the differences between the original document and the updated document.
The updateLookup setting returns the differences between the original document and updated document as well as a copy of the entire updated document at a point in time after the update.
The whenAvailable setting returns the updated document, if available.
The required setting returns the updated document and raises an error if it is not available.
For more information on how this change stream option works, see Lookup Full Document for Update Operations in the MongoDB manual.
Default: ""
Accepted Values: "", "updateLookup", "whenAvailable", or "required" |
flujo.de.cambios.full.documento.before.change | Type: string
Description:
Configures the document pre-image your change stream returns on update operations. The pre-image is not available for source records published while copying existing data, and the pre-image configuration has no effect on copying.
To learn how to configure a collection to enable pre-images, see Change Streams with Document Pre- and Post-Images in the MongoDB manual.
The default setting suppresses the document pre-image.
The whenAvailable setting returns the document pre-image if it's available, before it was replaced, updated, or deleted.
The required setting returns the document pre-image and raises an error if it is not available.
Default: ""
Accepted Values: "" or "whenAvailable" or "required" |
publish.full.document.only | Type: boolean
Description:
Whether to return only the fullDocument field from the change stream event document produced by any update event. The fullDocument field contains the most current version of the updated document. To learn more about the fullDocument field, see the update Event in the Server manual.
When set to true, the connector overrides the change.stream.full.document setting and sets it to updateLookup so that the fullDocument field contains updated documents.
Default: false
Accepted Values: true or false |
Solo document completo (tumba) al borrar | Type: boolean
Description:
Whether to return tombstone events when documents are deleted. Tombstone events contain the keys of deleted documents with null values. This setting applies only when publish.full.document.only is true.
Default: false
Accepted Values: true or false |
flujo de cambios.documento.key.as.key | Type: boolean
Description:
Whether to use the document key for the source record key if the document key is present.
When set to true, the connector adds keys of the deleted documents to the tombstone events. When set to false, the connector uses the resume token as the source key for the tombstone events.
Default: true
Accepted Values: true or false |
| Type: string
Description:
A JSON collation document that specifies language-specific ordering rules that MongoDB applies to the documents returned by the change stream.
Default: ""
Accepted Values: A valid collation JSON document |

Description:
The change stream cursor batch size.
Default: 0
Accepted Values: An integer |
| Type: long
Description:
The maximum amount of time in milliseconds that the server waits for new data changes to report to the change stream cursor before returning an empty batch.
Default: 5000
Accepted Values: An integer |
| Type: int
Description:
Maximum number of documents to read in a single batch when polling a change stream cursor for new data. You can use this setting to limit the amount of data buffered internally in the connector.
Default: 1000
Accepted Values: An integer |
