# Get started with AWS Kinesis

> Stream Postgres changes to an Amazon Kinesis stream in minutes with Sequin.

In this quickstart, you'll create a real-time data pipeline that streams changes from a Postgres database to an Amazon Kinesis data stream. You'll:

* Set up a Kinesis stream using the AWS CLI
* Create an IAM user with the minimal required permissions
* Boot Sequin and connect to a sample playground database
* Configure Sequin to stream database changes to your Kinesis stream
* See your changes flow in real-time

By the end, you'll have hands-on experience setting up Postgres change data capture (CDC) with Sequin and Kinesis.

<Tip>
  This is the quickstart for streaming Postgres to Kinesis. See the [how-to guide](/how-to/stream-postgres-to-kinesis) for an explanation of how to use the Kinesis sink or the [reference](/reference/sinks/kinesis) for details on all configuration options.
</Tip>

## Prerequisites

* AWS CLI installed and configured with your AWS credentials
* An AWS account with permissions to create Kinesis streams and IAM users

## Step 1: Set up your Kinesis stream

First, let's create a Kinesis stream and the necessary AWS resources using the AWS CLI.

<Steps>
  <Step title="Create a Kinesis stream">
    Run this command to create a new Kinesis stream called `sequin-quickstart`:

    ```bash theme={null}
    aws kinesis create-stream \
      --stream-name sequin-quickstart \
      --shard-count 1
    ```

    Wait for the stream to become active (this takes about 1-2 minutes):

    ```bash theme={null}
    aws kinesis describe-stream --stream-name sequin-quickstart
    ```

    Look for `"StreamStatus": "ACTIVE"` in the response.
  </Step>

  <Step title="Get your stream ARN">
    Once active, note down your stream ARN from the describe-stream output. It will look like:

    ```
    arn:aws:kinesis:us-east-1:123456789012:stream/sequin-quickstart
    ```

    You can also get just the ARN with:

    ```bash theme={null}
    aws kinesis describe-stream --stream-name sequin-quickstart --query 'StreamDescription.StreamARN' --output text
    ```
  </Step>

  <Step title="Create an IAM policy">
    Create a policy file called `sequin-kinesis-policy.json`:

    ```json theme={null}
    {
      "Version": "2012-10-17",
      "Statement": [
        {
          "Effect": "Allow",
          "Action": [
            "kinesis:PutRecords",
            "kinesis:DescribeStream"
          ],
          "Resource": "arn:aws:kinesis:*:*:stream/sequin-quickstart"
        }
      ]
    }
    ```

    Create the policy in AWS:

    ```bash theme={null}
    aws iam create-policy \
      --policy-name SequinKinesisPolicy \
      --policy-document file://sequin-kinesis-policy.json
    ```

    Note the policy ARN from the response - you'll need it in the next step.
  </Step>

  <Step title="Create an IAM user">
    Create a dedicated IAM user for Sequin:

    ```bash theme={null}
    aws iam create-user --user-name sequin-kinesis-user
    ```

    Attach the policy to the user (replace `YOUR_ACCOUNT_ID` with your AWS account ID):

    ```bash theme={null}
    aws iam attach-user-policy \
      --user-name sequin-kinesis-user \
      --policy-arn arn:aws:iam::YOUR_ACCOUNT_ID:policy/SequinKinesisPolicy
    ```

    If you don't have your account ID handy, you can ask AWS like this:

    ```bash theme={null}
    aws sts get-caller-identity --query Account --output text
    ```
  </Step>

  <Step title="Create access keys">
    Generate access keys for the user:

    ```bash theme={null}
    aws iam create-access-key --user-name sequin-kinesis-user
    ```

    **Important**: Save the `AccessKeyId` and `SecretAccessKey` from the response - you'll need these for Sequin configuration and they won't be shown again.
  </Step>
</Steps>

<Steps titleSize="h2">
  <Step title="Run Sequin" icon="server">
    The easiest way to get started with Sequin is with our [Docker Compose file](https://github.com/sequinstream/sequin/blob/main/docker/docker-compose.yaml). This file starts a Postgres database, Redis instance, and Sequin server.

    <Steps>
      <Step title="Create directory and start services">
        1. Download [sequin-docker-compose.zip](https://github.com/sequinstream/sequin/releases/latest/download/sequin-docker-compose.zip).
        2. Unzip the file.
        3. Navigate to the unzipped directory and start the services:

        ```bash theme={null}
        cd sequin-docker-compose && docker compose up -d
        ```

        <AccordionGroup>
          <Accordion title="Alternative: Download with curl">
            ```bash theme={null}
            curl -L https://github.com/sequinstream/sequin/releases/latest/download/sequin-docker-compose.zip -o sequin-docker-compose.zip \
              && unzip sequin-docker-compose.zip && rm sequin-docker-compose.zip
            cd sequin-docker-compose && docker compose up -d
            ```
          </Accordion>

          <Accordion title="Alternative: Clone the repository">
            ```bash theme={null}
            git clone git@github.com:sequinstream/sequin.git
            cd sequin/docker
            docker compose up -d
            ```
          </Accordion>
        </AccordionGroup>
      </Step>

      <Step title="Verify services are running">
        Check that Sequin is running using `docker ps`:

        ```bash theme={null}
        docker ps
        ```

        You should see output like the following:

        ```
        CONTAINER ID   IMAGE                           COMMAND                  CREATED          STATUS                    PORTS                              NAMES

        ```

        <Check>
          Sequin, Postgres, Redis, Prometheus, and Grafana should be up and running (status: `Up`).
        </Check>
      </Step>
    </Steps>
  </Step>

  <Step title="Login" icon="key">
    The Docker Compose file automatically configures Sequin with an admin user and a playground database.

    Let's log in to the Sequin web console:

    <Steps>
      <Step title="Open the web console">
        After starting the Docker Compose services, open the Sequin web console at [http://localhost:7376](http://localhost:7376):

        <Frame>
          <img src="https://mintcdn.com/sequinstream/drUA755uMUeIaCSH/images/quickstart/login-page.png?fit=max&auto=format&n=drUA755uMUeIaCSH&q=85&s=c5d90b34f56560570696a71370f7e39b" alt="Sequin login page, allowing login with default credentials" width="2070" height="1696" data-path="images/quickstart/login-page.png" />
        </Frame>
      </Step>

      <Step title="Login with default credentials">
        Use the following default credentials to login:

        * Email:

        ```
        admin@sequinstream.com
        ```

        * Password:

        ```
        sequinpassword!
        ```
      </Step>
    </Steps>
  </Step>

  <Step title="View the playground database" icon="database">
    To get you started quickly, Sequin's Docker Compose file creates a logical database called `sequin_playground` with a sample dataset in the `public.products` table.

    Let's take a look:

    <Steps>
      <Step title="Navigate to Databases">
        In the Sequin web console, click **Databases** in the sidebar.
      </Step>

      <Step title="Select playground database">
        Click on the pre-configured `sequin-playground` database:

        <Frame>
          <img src="https://mintcdn.com/sequinstream/drUA755uMUeIaCSH/images/quickstart/playground-database.png?fit=max&auto=format&n=drUA755uMUeIaCSH&q=85&s=01ac1cbf4506cad22c270adb66c0b171" alt="Playground database" width="3376" height="2020" data-path="images/quickstart/playground-database.png" />
        </Frame>

        <Check>
          The database "Health" should be green.
        </Check>
      </Step>

      <Step title="View contents of the products table">
        Let's get a sense of what's in the `products` table. Run the following command:

        ```bash theme={null}
        docker exec -i sequin-sequin_postgres-1 \
          psql -U postgres -d sequin_playground -c \
          "select id, name, price from products;"
        ```

        <Info>
          This command connects to the running Postgres container and runs a `psql` command.
        </Info>

        You should see a list of the rows in the `products` table:

        ```
          id |         name          | price 
        ----+-----------------------+-------
          1 | Avocados (3 pack)     |  5.99
          2 | Flank Steak (1 lb)    |  8.99
          3 | Salmon Fillet (12 oz) | 14.99
          4 | Baby Spinach (16 oz)  |  4.99
          5 | Sourdough Bread       |  6.99
          6 | Blueberries (6 oz)    |  3.99
        (6 rows)
        ```

        We'll make modifications to this table in a bit.
      </Step>
    </Steps>
  </Step>

  <Step title="Create a Kinesis Sink" icon="aws">
    With the playground database connected, create a [sink](/reference/sinks/overview) that will send changes to your Kinesis stream:

    <Steps>
      <Step title="Navigate to Sinks">
        Click "Sinks" in the sidebar navigation, then click "Create Sink".
      </Step>

      <Step title="Select sink type">
        Select "Amazon Kinesis" as the sink type and click "Continue".
      </Step>

      <Step title="Note &#x22;Source&#x22; configuration">
        In the "Source" card, note that the `sequin-playground` database is selected and all schemas and tables are included. Leave these defaults:

      <Step title="Configure Kinesis connection">
        In the Kinesis configuration card, enter:

        * **Stream ARN**: The ARN you noted from Step 1 (e.g., `arn:aws:kinesis:us-east-1:123456789012:stream/sequin-quickstart`)
        * **AWS Access Key ID**: The `AccessKeyId` from Step 1
        * **AWS Secret Access Key**: The `SecretAccessKey` from Step 1
        * **AWS Region**: The region where you created your stream (e.g., `us-east-1`)
      </Step>

      <Step title="Create the sink">
        Click "Create Sink" to finish setting up your Kinesis sink.
      </Step>
    </Steps>
  </Step>

  <Step title="See changes flow to your Kinesis stream" icon="waveform-lines">
    On the new sink's overview page, you should see the "Health" status turn green, indicating data is flowing to your stream.

    <Steps>
      <Step title="Messages tab">
        Click the "Messages" tab to see recently delivered messages.
      </Step>

      <Step title="Verify in AWS (optional)">
        You can also verify data is flowing by checking your Kinesis stream in the AWS Console or using the CLI:

        ```bash theme={null}
        aws kinesis get-records \
          --shard-iterator $(aws kinesis get-shard-iterator \
            --stream-name sequin-quickstart \
            --shard-id shardId-000000000000 \
            --shard-iterator-type TRIM_HORIZON \
            --query 'ShardIterator' --output text) \
          --query 'Records[0].Data' --output text | base64 -d
        ```
      </Step>
    </Steps>
  </Step>
</Steps>

<Check>
  Great work!
</Check>

You've successfully:

* Created a Kinesis stream with the AWS CLI
* Set up an IAM user with minimal required permissions
* Connected Sequin to stream Postgres changes to Kinesis
* Loaded existing data through a backfill
* Verified changes are flowing to your Kinesis stream

## Clean up (optional)

If you want to clean up the AWS resources created in this quickstart:

```bash theme={null}
# Delete the Kinesis stream
aws kinesis delete-stream --stream-name sequin-quickstart

# Detach policy from user
aws iam detach-user-policy \
  --user-name sequin-kinesis-user \
  --policy-arn arn:aws:iam::YOUR_ACCOUNT_ID:policy/SequinKinesisPolicy

# Delete access key (replace with your actual access key ID)
aws iam delete-access-key \
  --user-name sequin-kinesis-user \
  --access-key-id YOUR_ACCESS_KEY_ID

# Delete user and policy
aws iam delete-user --user-name sequin-kinesis-user
aws iam delete-policy --policy-arn arn:aws:iam::YOUR_ACCOUNT_ID:policy/SequinKinesisPolicy
```
