## [](#credentials)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](https://docs.redpanda.com/cloud-data-platform/develop/connect/guides/cloud/aws/).

## [](#performance)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)Fields

### [](#credentials-2)`credentials`

Optional manual configuration of AWS credentials to use. More information can be found in [Amazon Web Services](https://docs.redpanda.com/cloud-data-platform/develop/connect/guides/cloud/aws/).

**Type**: `object`

### [](#credentials-from_ec2_role)`credentials.from_ec2_role`

Use the credentials of a host EC2 machine configured to assume [an IAM role associated with the instance](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2.html).

**Type**: `bool`

### [](#credentials-id)`credentials.id`

The ID of credentials to use.

**Type**: `string`

### [](#credentials-profile)`credentials.profile`

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

**Type**: `string`

### [](#credentials-role)`credentials.role`

A role ARN to assume.

**Type**: `string`

### [](#credentials-role_external_id)`credentials.role_external_id`

An external ID to provide when assuming a role.

**Type**: `string`

### [](#credentials-secret)`credentials.secret`

The secret for the credentials being used.

> ⚠️ **CAUTION**
>
> This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see [Manage Secrets](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/secret-management/) before adding it to your configuration.

**Type**: `string`

### [](#credentials-token)`credentials.token`

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

**Type**: `string`

### [](#endpoint)`endpoint`

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

**Type**: `string`

### [](#max_in_flight)`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)`message_deduplication_id`

An optional deduplication ID to set for messages. This field supports [interpolation functions](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/interpolation/#bloblang-queries).

**Type**: `string`

### [](#message_group_id)`message_group_id`

An optional group ID to set for messages. This field supports [interpolation functions](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/interpolation/#bloblang-queries).

**Type**: `string`

### [](#metadata)`metadata`

Specify criteria for which metadata values are sent as headers.

**Type**: `object`

### [](#metadata-exclude_prefixes)`metadata.exclude_prefixes[]`

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

**Type**: `array`

**Default**: `[]`

### [](#region)`region`

The AWS region to target.

**Type**: `string`

### [](#subject)`subject`

An optional subject to set for messages.

This field supports [interpolation functions](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/interpolation/#bloblang-queries).

**Type**: `string`

### [](#tcp)`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)`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`

TCP keep-alive probe configuration.

**Type**: `object`

### [](#tcp-keep_alive-count)`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)`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)`tcp.keep_alive.interval`

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

**Type**: `string`

**Default**: `15s`

### [](#tcp-tcp_user_timeout)`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)`timeout`

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

**Type**: `string`

**Default**: `5s`

### [](#topic_arn)`topic_arn`

The topic to publish to.

This field supports [interpolation functions](https://docs.redpanda.com/cloud-data-platform/develop/connect/configuration/interpolation/#bloblang-queries).
