Performance

This output benefits from sending multiple messages in flight in parallel for improved performance. You can tune the max number of in flight messages (or message batches) with the field max_in_flight.

This output benefits from sending messages as a batch for improved performance. Batches can be formed at both the input and output level. You can find out more in this doc.

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.

This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Secrets.

Type: string

Default: ""

app_name

The client application name.

Type: string

Default: "benthos"

collection

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

Type: string

operation

The mongodb operation to perform.

Type: string

Default: "update-one"

Options: insert-one , delete-one , delete-many , replace-one , update-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 3.60.0 or newer

max_in_flight

The maximum number of messages to have in flight at a given time. Increase this to improve throughput.

Type: int

Default: 64

batching

Allows you to configure a batching policy.

Type: object

# Examples

batching:
  byte_size: 5000
  count: 0
  period: 1s

batching:
  count: 10
  period: 1s

batching:
  check: this.contains("END BATCH")
  count: 0
  period: 1m

batching.count

A number of messages at which the batch should be flushed. If 0 disables count based batching.

Type: int

Default: 0

batching.byte_size

An amount of bytes at which the batch should be flushed. If 0 disables size based batching.

Type: int

Default: 0

batching.period

A period in which an incomplete batch should be flushed regardless of its size.

Type: string

Default: ""

# Examples

period: 1s

period: 1m

period: 500ms

batching.check

A Bloblang query that should return a boolean value indicating whether a message should end a batch.

Type: string

Default: ""

# Examples

check: this.type == "end_of_transaction"

batching.processors

A list of processors to apply to a batch as it is flushed. This allows you to aggregate and archive the batch however you see fit. Please note that all resulting messages are flushed as a single batch, therefore splitting the batch into smaller batches using these processors is a no-op.

Type: array

# Examples

processors:
  - archive:
      format: concatenate

processors:
  - archive:
      format: lines

processors:
  - archive:
      format: json_array
