Weaviate

Batch process all your records to store structured outputs in a Weaviate database.

The requirements are as follows.

• For the Unstructured Platform: only Weaviate Cloud clusters are supported.

• For Unstructured Ingest: Weaviate Cloud clusters, Weaviate installed locally, and Embedded Weaviate are supported.

• For Weaviate installed locally, you will need the name of the target collection on the local instance.

• For Embedded Weaviate, you will need the instance’s connection URL and the name of the target collection on the instance.

• For Weaviate Cloud, you will need:

  • A Weaviate database instance. The following information assumes that you have a Weaviate Cloud (WCD) account with a Weaviate database cluster in that account. Create a WCD account. Create a database cluster. For other database options, learn more.
  • The URL and API key for the database cluster. Get the URL and API key.
  • The name of the target collection in the database. Create a collection.

Weaviate requires the collection to have a data schema before you add data. At minimum, this schema must contain the record_id property, as follows:

{
    "class": "Elements",
    "properties": [
        {
            "name": "record_id",
            "dataType": ["text"]
        }
    ]
}

Weaviate generates any additional properties based on the incoming data.

If you have specific schema requirements, you can define the schema manually. Unstructured cannot provide a schema that is guaranteed to work for everyone in all circumstances. This is because these schemas will vary based on your source files’ types; how you want Unstructured to partition, chunk, and generate embeddings; any custom post-processing code that you run; and other factors.

You can adapt the following collection schema example for your own specific schema requirements:

{
    "class": "Elements",
    "properties": [
        {
            "name": "record_id",
            "dataType": ["text"]
        },
        {
            "name": "element_id",
            "dataType": ["text"]
        },
        {
            "name": "text",
            "dataType": ["text"]
        },
        {
            "name": "embeddings",
            "dataType": ["number[]"]
        },
        {
            "name": "metadata",
            "dataType": ["object"],
            "nestedProperties": [
                {
                    "name": "parent_id",
                    "dataType": ["text"]
                },
                {
                    "name": "page_number",
                    "dataType": ["text"]
                },
                {
                    "name": "is_continuation",
                    "dataType": ["boolean"]
                },
                {
                    "name": "orig_elements",
                    "dataType": ["text"]
                }
            ]
        }
    ]
}

The Weaviate connector dependencies:

pip install "unstructured-ingest[weaviate]"

You might also need to install additional dependencies, depending on your needs. Learn more.

The following environment variables:

• For Weaviate installed locally, WEAVIATE_COLLECTION - The name of the target collection in the instance, represented by --collection (CLI) or collection (Python).

• For Embedded Weaviate:

  • WEAVIATE_HOST - The connection URL to the instance, represented by --hostname (CLI) or hostname (Python).
  • WEAVIATE_COLLECTION - The name of the target collection in the instance, represented by --collection (CLI) or collection (Python).

• For Weaviate Cloud:

  • WEAVIATE_CLUSTER_URL - THE REST endpoint for the Weaviate database cluster, represented by --cluster-url (CLI) or cluster_url (Python).

  • WEAVIATE_API_KEY - The API key for the database cluster, represented by --api-key (CLI) or api_key (Python).

    For the CLI, the --api-key option here is part of the weaviate-cloud command. For Python, the api_key parameter here is part of the CloudWeaviateAccessConfig object.

  • WEAVIATE_COLLECTION - The name of the target collection in the database, represented by --collection (CLI) or collection (Python).

Now call the Unstructured Ingest CLI or the Unstructured Ingest Python library. The source connector can be any of the ones supported. This example uses the local source connector:

This example sends files to Unstructured API services for processing by default. To process files locally instead, see the instructions at the end of this page.

For the Unstructured Ingest CLI and the Unstructured Ingest Python library, you can use the --partition-by-api option (CLI) or partition_by_api (Python) parameter to specify where files are processed:

• To do local file processing, omit --partition-by-api (CLI) or partition_by_api (Python), or explicitly specify partition_by_api=False (Python).

  Local file processing does not use an Unstructured API key or API URL, so you can also omit the following, if they appear:

  • --api-key $UNSTRUCTURED_API_KEY (CLI) or api_key=os.getenv("UNSTRUCTURED_API_KEY") (Python)
  • --partition-endpoint $UNSTRUCTURED_API_URL (CLI) or partition_endpoint=os.getenv("UNSTRUCTURED_API_URL") (Python)
  • The environment variables UNSTRUCTURED_API_KEY and UNSTRUCTURED_API_URL

• To send files to Unstructured API services for processing, specify --partition-by-api (CLI) or partition_by_api=True (Python).

  Unstructured API services also requires an Unstructured API key and API URL, by adding the following:

  • --api-key $UNSTRUCTURED_API_KEY (CLI) or api_key=os.getenv("UNSTRUCTURED_API_KEY") (Python)
  • --partition-endpoint $UNSTRUCTURED_API_URL (CLI) or partition_endpoint=os.getenv("UNSTRUCTURED_API_URL") (Python)
  • The environment variables UNSTRUCTURED_API_KEY and UNSTRUCTURED_API_URL, representing your API key and API URL, respectively.

  Get an API key and API URL.
