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.

Fields

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.

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 Manage Secrets before adding it to your configuration.

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

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

message_deduplication_id

An optional deduplication ID to set for messages. This field supports interpolation functions.

Type: string

message_group_id

An optional group ID to set for messages. This field supports interpolation functions.

Type: string

metadata

Specify criteria for which metadata values are sent as headers.

Type: object

metadata.exclude_prefixes[]

Provide a list of explicit metadata key prefixes to be excluded when adding metadata to sent messages.

Type: array

Default: []

region

The AWS region to target.

Type: string

tcp

Configure TCP socket-level settings to optimize network performance and reliability. These low-level controls are useful for:

  • High-latency networks: Increase connect_timeout to allow more time for connection establishment

  • Long-lived connections: Configure keep_alive settings to detect and recover from stale connections

  • Unstable networks: Tune keep-alive probes to balance between quick failure detection and avoiding false positives

  • Linux systems with specific requirements: Use tcp_user_timeout (Linux 2.6.37+) to control data acknowledgment timeouts

Most users should keep the default values. Only modify these settings if you’re experiencing connection stability issues or have specific network requirements.

Type: object

tcp.connect_timeout

Maximum amount of time a dial will wait for a connect to complete. Zero disables.

Type: string

Default: 0s

tcp.keep_alive

TCP keep-alive probe configuration.

Type: object

tcp.keep_alive.count

Maximum unanswered keep-alive probes before dropping the connection. Zero defaults to 9.

Type: int

Default: 9

tcp.keep_alive.idle

Duration the connection must be idle before sending the first keep-alive probe. Zero defaults to 15s. Negative values disable keep-alive probes.

Type: string

Default: 15s

tcp.keep_alive.interval

Duration between keep-alive probes. Zero defaults to 15s.

Type: string

Default: 15s

tcp.tcp_user_timeout

Maximum time to wait for acknowledgment of transmitted data before killing the connection. Linux-only (kernel 2.6.37+), ignored on other platforms. When enabled, keep_alive.idle must be greater than this value per RFC 5482. Zero disables.

Type: string

Default: 0s

timeout

The maximum period to wait on an upload before abandoning it and reattempting.

Type: string

Default: 5s

topic_arn

The topic to publish to.

This field supports interpolation functions.

Type: string
