**Type:** Output ▼

[Output](https://docs.redpanda.com/connect/components/outputs/aws_kinesis/)[Input](https://docs.redpanda.com/connect/components/inputs/aws_kinesis/)

**Available in:** [Cloud](https://docs.redpanda.com/cloud-data-platform/develop/connect/components/outputs/aws_kinesis/%20%22View%20the%20Cloud%20version%20of%20this%20component%22), Self-Managed

Sends messages to a Kinesis stream.

Introduced in version 3.36.0.

#### Common

```yml
outputs:
  label: ""
  aws_kinesis:
    stream: "" # No default (required)
    partition_key: "" # No default (required)
    max_in_flight: 64
    batching:
      count: 0
      byte_size: 0
      period: ""
      check: ""
      processors: [] # No default (optional)
```

#### Advanced

```yml
outputs:
  label: ""
  aws_kinesis:
    stream: "" # No default (required)
    partition_key: "" # No default (required)
    hash_key: "" # No default (optional)
    max_in_flight: 64
    batching:
      count: 0
      byte_size: 0
      period: ""
      check: ""
      processors: [] # No default (optional)
    region: "" # No default (optional)
    endpoint: "" # No default (optional)
    tcp:
      connect_timeout: 0s
      keep_alive:
        idle: 15s
        interval: 15s
        count: 9
      tcp_user_timeout: 0s
    credentials:
      profile: "" # No default (optional)
      id: "" # No default (optional)
      secret: "" # No default (optional)
      token: "" # No default (optional)
      from_ec2_role: "" # No default (optional)
      role: "" # No default (optional)
      role_external_id: "" # No default (optional)
    max_retries: 0
    backoff:
      initial_interval: 1s
      max_interval: 5s
      max_elapsed_time: 30s
```

Both the `partition_key`(required) and `hash_key` (optional) fields can be dynamically set using function interpolations described [here](https://docs.redpanda.com/connect/configuration/interpolation/#bloblang-queries). When sending batched messages the interpolations are performed per message part.

## [](#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/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`.

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](https://docs.redpanda.com/connect/configuration/batching/).

## [](#fields)Fields

### [](#backoff)`backoff`

Control time intervals between retry attempts.

**Type**: `object`

### [](#backoff-initial_interval)`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. This field accepts Go duration format strings such as `100ms`, `1s`, or `5s`.

**Type**: `string`

**Default**: `1s`

### [](#backoff-max_elapsed_time)`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)`backoff.max_interval`

The maximum period to wait between retry attempts.

**Type**: `string`

**Default**: `5s`

### [](#batching)`batching`

Allows you to configure a [batching policy](https://docs.redpanda.com/connect/configuration/batching/).

**Type**: `object`

```yaml
# 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)`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)`batching.check`

A [Bloblang query](https://docs.redpanda.com/connect/guides/bloblang/about/) that should return a boolean value indicating whether a message should end a batch.

**Type**: `string`

**Default**: `""`

```yaml
# Examples:
check: this.type == "end_of_transaction"
```

### [](#batching-count)`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)`batching.period`

A period in which an incomplete batch should be flushed regardless of its size.

**Type**: `string`

**Default**: `""`

```yaml
# Examples:
period: 1s

# ---

period: 1m

# ---

period: 500ms
```

### [](#batching-processors)`batching.processors[]`

A list of [processors](https://docs.redpanda.com/connect/components/processors/about/) 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`

```yaml
# Examples:
processors:
  - archive:
      format: concatenate

# ---

processors:
  - archive:
      format: lines

# ---

processors:
  - archive:
      format: json_array
```

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

stream: foo

# ---

stream: arn:aws:kinesis:*:111122223333:stream/my-stream
```

### [](#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`

**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`
