SingleStore

Batch process all your records to store structured outputs in a SingleStore account.

You will need:

The SingleStore prerequisites:

• A SingleStore deployment, database, and table. Learn how.
• The hostname for the SingleStore deployment.
• The port for the host.
• The username for the deployment.
• The password for the user.
• The name of the database in the deployment.
• The name of the table in the database.

To get the values for the hostname, port, username, and password:

1. In your SingleStore account’s dashboard sidebar, click Deployments.
2. From the drop-down list at the top of the Deployments page, select your deployment.
3. On the Overview tab, in the Compute area, in the Connect drop-down list for your deployment, select Your App.
4. If a Create User dialog box appears, note the User name and Password values.
5. In the Connect to Workspace pane’s Your App tab, note the string in the following format:

<user-name>:<password>@<host>:<port>

• <user-name> is the username.
• <password> is the user’s password.
• <host> is the workspace’s hostname.
• <post> is the host’s port.

To get the values for the database and table names:

1. In your SingleStore dashboard’s sidebar, click Deployments.
2. From the drop-down list at the top of the Deployments page, select your deployment.
3. On the Databases tab, note Name of your database.
4. Click the database and, on the Tables tab, note the name of your table.

The SingleStore connector dependencies:

pip install "unstructured-ingest[singlestore]"

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

These environment variables:

• SINGLESTORE_HOST - The hostname for the SingleStore deployment, represented by --host (CLI) or host (Python).
• SINGLESTORE_PORT - The port for the host, represented by --port (CLI) or port (Python).
• SINGLESTORE_USER - The username for the deployment, represented by --user (CLI) or user (Python).
• SINGLESTORE_PASSWORD - The password for the user, represented by --password (CLI) or password (Python).
• SINGLESTORE_DB - The name of the database in the deployment, represented by --database (CLI) or database (Python).
• SINGLESTORE_TABLE - The name of the table in the database, represented by --table-name (CLI) or table_name (Python).

The table’s schema must match the schema of the documents that Unstructured produces.

During insertion, JSON objects are flattened, and underscores are placed between nested object names. For example, the following JSON object matches a column in the table named data_source_date_created:

{
    "...": "...",
    "data_source": {
        "date_created": "1719963233.949"
    },
    "...": "..."
}

The metadata object itself is also flattened in a similar way. However, for nested objects in metadata, the column in the table does not start with metadata_. For example, the following JSON object matches a column in the table named last_modified:

{
    "...": "...",
    "metadata": {
        "...": "...",
        "last_modified": "2022-12-16T17:04:16-05:00",
        "...": "..."
    },
    "...": "..."
}

Unstructured cannot provide a table schema that is guaranteed to work 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 table schema example for your own needs:

CREATE TABLE elements (
    id INT PRIMARY KEY NOT NULL AUTO_INCREMENT,
    element_id TEXT,
    text TEXT,
    embeddings Vector(384),
    parent_id TEXT,
    page_number TEXT,
    is_continuation BOOLEAN,
    orig_elements TEXT
);

• Unstructured document elements and metadata

These environment variables:

• UNSTRUCTURED_API_KEY - Your Unstructured API key value.
• UNSTRUCTURED_API_URL - Your Unstructured API URL.

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:
