# Astra DB

<Note>
  If you're new to Unstructured, read this note first.

  Before you can create a destination connector, you must first [sign up for Unstructured](https://platform.unstructured.io) and get your
  Unstructured API key. After you sign up, the [Unstructured user interface](/ui/overview) (UI) appears, which you use to get the key.
  To learn how, watch this 40-second [how-to video](https://www.youtube.com/watch?v=FucugLkYB6M).

  After you create the destination connector, add it along with a
  [source connector](/api-reference/workflow/sources/overview) to a [workflow](/api-reference/workflow/overview#workflows).
  Then run the worklow as a [job](/api-reference/workflow/overview#jobs). To learn how, try out the
  [hands-on Workflow Endpoint quickstart](/api-reference/workflow/overview#quickstart),
  go directly to the [quickstart notebook](https://colab.research.google.com/drive/13f5C9WtUvIPjwJzxyOR3pNJ9K9vnF4ww),
  or watch the two 4-minute video tutorials for the [Unstructured Python SDK](/api-reference/workflow/overview#unstructured-python-sdk).

  You can also create destination connectors with the Unstructured user interface (UI).
  [Learn how](/ui/destinations/overview).

  If you need help, reach out to the [community](https://short.unstructured.io/pzw05l7) on Slack, or
  [contact us](https://unstructured.io/contact) directly.

  You are now ready to start creating a destination connector! Keep reading to learn how.

* An Astra account. [Create or sign in to an Astra account](https://astra.datastax.com/).
* A database in the Astra account. [Create a database in an account](https://docs.datastax.com/en/astra-db-classic/databases/manage-create.html).

To create an Astra DB destination connector, see the following examples.

<CodeGroup>
  ```python Python SDK theme={null}
  import os

  from unstructured_client import UnstructuredClient
  from unstructured_client.models.operations import CreateDestinationRequest
  from unstructured_client.models.shared import (
      CreateDestinationConnector,
      DestinationConnectorType,
      AstraDBConnectorConfigInput
  )

  with UnstructuredClient(api_key_auth=os.getenv("UNSTRUCTURED_API_KEY")) as client:
      response = client.destinations.create_destination(
          request=CreateDestinationRequest(
              create_destination_connector=CreateDestinationConnector(
                  name="<name>",
                  type=DestinationConnectorType.ASTRADB,
                  config=AstraDBConnectorConfigInput(
                      token="<token>",
                      api_endpoint="<api-endpoint>",
                      collection_name="<collection-name>",
                      keyspace="<keyspace>",
                      batch_size=<batch-size>,
                      flatten_metadata=<True|False>
                  )
              )
          )
      )

      print(response.destination_connector_information)
  ```

  ```bash curl theme={null}
  curl --request 'POST' --location \
  "$UNSTRUCTURED_API_URL/destinations" \
  --header 'accept: application/json' \
  --header "unstructured-api-key: $UNSTRUCTURED_API_KEY" \
  --header 'content-type: application/json' \
  --data \
  '{
      "name": "<name>",
      "type": "astradb",
      "config": {
          "token": "<token>",
          "api_endpoint": "<api-endpoint>",
          "collection_name": "<collection-name>",
          "keyspace": "<keyspace>",
          "batch_size": <batch-size>,
          "flatten_metadata": "<true|false>"
      }
  }'
  ```
</CodeGroup>

Replace the preceding placeholders as follows:

* `<name>` (*required*) - A unique name for this connector.
* `<token>` (*required*) - The application token for the database.
* `<api-endpoint>` (*required*) - The database’s associated API endpoint.
* `<collection-name>` (*required*) - The name of the collection in the namespace.
* `<keyspace>` - The name of the keyspace in the collection. The default is `default_keyspace` if not otherwise specified.
* `<batch-size>` - The maximum number of records to send per batch. The default is `20` if not otherwise specified.
* `flatten_metadata` - Set to `true` to flatten the metadata into each record. Specifically, when flattened, the metadata key values are brought to the top level of the element, and the `metadata` key itself is removed. By default, the metadata is not flattened (`false`).
