​
Objectives

  1. Extract text and metadata from a PDF file using the Unstructured.io Python SDK.
  2. Process and store this data in a Databricks Delta Table.
  3. Retrieve data from the Delta Table using the Unstructured.io Delta Table Connector.

​
Prerequisites

  • Unstructured Python SDK
  • Databricks account and workspace
  • AWS S3 for Delta Table storage

​
Processing and Storing into Databricks Delta Table

  1. Initialize PySpark
from pyspark.sql import SparkSession

spark = SparkSession.builder.appName('sparkdf').getOrCreate()
  1. Convert JSON output into Dataframe
import pyspark

dataframe = spark.createDataFrame(res.elements)
  1. Store DataFrame as Delta Table
dataframe.write.mode("overwrite").format("delta").saveAsTable("delta_table")

​
Conclusion

This documentation covers the essential steps for converting unstructured PDF data into structured data and storing it in a Databricks Delta Table. It also outlines how to extract this data for further use.
