SQLite

Batch process all your records to store structured outputs in a SQLite schema.

Insert query is currently limited to append.

The requirements are as follows.

• A SQLite instance. Download and install SQLite.

• A SQLite database. Create a database.

• The path to the database’s .db file.

• A table in the database. Create a table.

  The table’s schema must match the schema of the documents that Unstructured produces. Unstructured cannot provide a 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:

  SQLite

  CREATE TABLE elements (
      id TEXT PRIMARY KEY,
      record_id TEXT,
      element_id TEXT,
      text TEXT,
      embeddings TEXT,
      parent_id TEXT,
      page_number INTEGER,
      is_continuation INTEGER,
      orig_elements TEXT
  );

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

The following environment variables:

• SQLITE_DB_PATH - The path to the database’s .db file, represented by --database (CLI) or database (Python).

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:
