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 DB.
Type: string
Default: ""
# Examples
url: mongodb://localhost:27017
database
The name of the target MongoDB DB.
Type: string
Default: ""
username
The username to connect to the database.
Type: string
Default: ""
password
The password to connect to the database.
Type: string
Default: ""
operation
The mongodb operation to perform.
Type: string
Default: "update-one"
Options: insert-one
, delete-one
, delete-many
, replace-one
, update-one
.
collection
The name of the target collection in the MongoDB DB. This field supports interpolation functions.
Type: string
Default: ""
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 the records in the mongo db. Used to generate the document for mongodb by mapping the fields in the message to the mongodb fields. 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 the filter for the mongo db command. 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 mongo db command. 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 parallel message batches to have in flight at any given time.
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
Default: []
# Examples
processors:
- archive:
format: concatenate
processors:
- archive:
format: lines
processors:
- archive:
format: json_array
max_retries
The maximum number of retries before giving up on the request. If set to zero there is no discrete limit.
Type: int
Default: 3
backoff
Control time intervals between retry attempts.
Type: object
backoff.initial_interval
The initial period to wait between retry attempts.
Type: string
Default: "1s"
backoff.max_interval
The maximum period to wait between retry attempts.
Type: string
Default: "5s"
backoff.max_elapsed_time
The maximum period to wait before retry attempts are abandoned. If zero then no limit is used.
Type: string
Default: "30s"
