# Delta Table

Connect Delta Table to your preprocessing pipeline, and batch process all your documents using `unstructured-ingest` to
store structured outputs locally on your filesystem.

Make sure to have the Delta Table dependencies installed:

```bash Shell theme={null}
pip install "unstructured-ingest[delta-table]"
```

AWS credentials need to be available for use with the storage options.
Specify the to the DeltaTable using the `table-uri` argument, and pass a dictionary of the options to use for the storage backend
via `storage_options`.

  ```bash Shell theme={null}
  #!/usr/bin/env bash

  unstructured-ingest \
    delta-table \
      --table-uri s3://utic-dev-tech-fixtures/sample-delta-lake-data/deltatable/ \
      --output-dir $LOCAL_FILE_OUTPUT_DIR \
      --storage_options "AWS_REGION=us-east-2,AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID,AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY" \
      --verbose \
      --strategy hi_res
  ```
