Fields​

url​

The URL of the target MongoDB server.

Type: string

# Examples

url: mongodb://localhost:27017

database​

The name of the target MongoDB database.

Type: string

username​

The username to connect to the database.

Type: string
Default: ""

password​

The password to connect to the database.

Secret

This field contains sensitive information that usually shouldn't be added to a config directly, read our secrets page for more info.

Type: string
Default: ""

collection​

The name of the target collection. This field supports interpolation functions.

Type: string

operation​

The mongodb operation to perform.

Type: string
Default: "insert-one"
Options: insert-one, delete-one, delete-many, replace-one, update-one, find-one.

write_concern​

The write concern settings for the mongo connection.

Type: object

write_concern.w​

W requests acknowledgement that write operations propagate to the specified number of mongodb instances.

Type: string
Default: ""

write_concern.j​

J requests acknowledgement from MongoDB that write operations are written to the journal.

Type: bool
Default: false

write_concern.w_timeout​

The write concern timeout.

Type: string
Default: ""

document_map​

A bloblang map representing a document to store within MongoDB, expressed as extended JSON in canonical form. The document map is required for the operations insert-one, replace-one and update-one.

Type: string
Default: ""

# Examples

document_map: |-
  root.a = this.foo
  root.b = this.bar

filter_map​

A bloblang map representing a filter for a MongoDB command, expressed as extended JSON in canonical form. The filter map is required for all operations except insert-one. It is used to find the document(s) for the operation. For example in a delete-one case, the filter map should have the fields required to locate the document to delete.

Type: string
Default: ""

# Examples

filter_map: |-
  root.a = this.foo
  root.b = this.bar

hint_map​

A bloblang map representing the hint for the MongoDB command, expressed as extended JSON in canonical form. This map is optional and is used with all operations except insert-one. It is used to improve performance of finding the documents in the mongodb.

Type: string
Default: ""

# Examples

hint_map: |-
  root.a = this.foo
  root.b = this.bar

upsert​

The upsert setting is optional and only applies for update-one and replace-one operations. If the filter specified in filter_map matches, the document is updated or replaced accordingly, otherwise it is created.

Type: bool
Default: false
Requires version 1.0.0 or newer

json_marshal_mode​

The json_marshal_mode setting is optional and controls the format of the output message.

Type: string
Default: "canonical"

OptionSummary
canonicalA string format that emphasizes type preservation at the expense of readability and interoperability. That is, conversion from canonical to BSON will generally preserve type information except in certain specific cases.
relaxedA string format that emphasizes readability and interoperability at the expense of type preservation. That is, conversion from relaxed format to BSON can lose type information.
