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 xref:guides:cloud/aws.adoc[].

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

`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

`partition_key`

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

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

`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

`region`

The AWS region to target.

Type: string

Default: ""

`endpoint`

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

Type: string

Default: ""

`credentials`

Optional manual configuration of AWS credentials to use. More information can be found in xref:guides:cloud/aws.adoc[].

Type: object

`credentials.profile`

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

Type: string

Default: ""

`credentials.id`

The ID of credentials to use.

Type: string

Default: ""

`credentials.secret`

The secret for the credentials being used.

Type: string

Default: ""

`credentials.token`

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

Type: string

Default: ""

`credentials.from_ec2_role`

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

Type: bool

Default: false Requires version 4.2.0 or newer

`credentials.role`

A role ARN to assume.

Type: string

Default: ""

`credentials.role_external_id`

An external ID to provide when assuming a role.

Type: string

Default: ""

`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

`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"
