Methods to Integrate Data from AWS DocumentDB to Databricks

The following methods will teach you how to connect AWS DocumentDB to Databricks. 

Method 1: Data Migration from AWS DocumentDB to Databricks Using CSV Files

Step 1: Export Data from AWS Document DB into CSV File 

AWS DocumentDB uses the mongoexport tool to extract data from the AWS DocumentDB cluster and convert it to a CSV file on your local system. 

mongoexport --ssl \

    --host="sample-cluster.node.us-east-1.docdb.amazonaws.com:27017" \

    --collection=sample-collection \

    --db=sample-database \

    --out=sample-output-file \

    --username=sample-user \

    --password=abc0123 \

    --sslCAFile global-bundle.pem

Step 2: Import Data from the CSV File to Databricks Using Add Data UI

You can use Add Data UI in Databricks to ingest data from a CSV file to Databricks. Follow the steps below for this: 

  • Login to your Databricks account, go to the Navigation Pane and click on New
AWS DocumentDB to Databricks: Databricks  Functions Tab
AWS DocumentDB to Databricks: Databricks  Functions Tab
  • Click on Data>Add Data
AWS DocumentDB to Databricks: CSV Databricks Export
AWS DocumentDB to Databricks: CSV Databricks Export
  • Then, find or drag and drop your CSV files directly into the drop zone.
AWS DocumentDB to Databricks: CSV Databricks Export
AWS DocumentDB to Databricks: CSV Databricks Export
  • You can choose either Create Table in UI or Create Table in Notebook.
AWS DocumentDB to Databricks: CSV Databricks Export
AWS DocumentDB to Databricks: CSV Databricks Export
  • Execute the Run command in the Notebook to view the exported CSV data in Databricks.

Limitations for Data Migration from AWS DocumentDB to Databricks Using CSV Files

  • CSV files don’t support large data files with complex data types, making it difficult to process data on a large scale and perform advanced analytics.
  • The mongoexport tool doesn’t support parallel exports when extracting data from the AWS DocumentDB. It means you can not break your exports into smaller parts to speed up the process.
  •  In Databricks, the file upload page support allows you to upload ten files at a time. This means you must collect data in batches, which makes the process lengthy.
