Both the partition_key(required) and hash_key (optional) fields can be dynamically set using function interpolations described here. When sending batched messages the interpolations are performed per message part.

Credentials

By default Redpanda Connect will use a shared credentials file when connecting to AWS services. It’s also possible to set them explicitly at the component level, allowing you to transfer data across accounts. You can find out more in Amazon Web Services.

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

backoff

Control time intervals between retry attempts.

Type: object

backoff.initial_interval

The initial period to wait between retry attempts. The retry interval increases for each failed attempt, up to the backoff.max_interval value.

Type: string

Default: 1s

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

backoff.max_interval

The maximum period to wait between retry attempts.

Type: string

Default: 5s

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.byte_size

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

Type: int

Default: 0

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.count

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

# Examples:
processors:
  - archive:
      format: concatenate

  - archive:
      format: lines

  - archive:
      format: json_array

credentials

Optional manual configuration of AWS credentials to use. More information can be found in Amazon Web Services.

Type: object

credentials.from_ec2_role

Use the credentials of a host EC2 machine configured to assume an IAM role associated with the instance.

Requires version 4.2.0 or later.

Type: bool

credentials.id

The ID of credentials to use.

Type: string

credentials.profile

A profile from ~/.aws/credentials to use.

Type: string

credentials.role

A role ARN to assume.

Type: string

credentials.role_external_id

An external ID to provide when assuming a role.

Type: string

credentials.secret

The secret for the credentials being used.

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

Type: string

credentials.token

The token for the credentials being used, required when using short term credentials.

Type: string

endpoint

Allows you to specify a custom endpoint for the AWS API.

Type: string

hash_key

A optional hash key for partitioning messages. This field supports interpolation functions.

Type: string

max_in_flight

The maximum number of parallel message batches to have in flight at any given time.

Type: int

Default: 64

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: 0

partition_key

A required key for partitioning messages. This field supports interpolation functions.

Type: string

region

The AWS region to target.

Type: string

stream

The stream to publish messages to. Streams can either be specified by their name or full ARN.

Type: string

# Examples:
stream: foo
stream: arn:aws:kinesis:*:111122223333:stream/my-stream
