Bulk Ingest of Salesforce Data Into Databricks Delta Lake

By Posted in Data Integration June 27, 2020

StreamSets is proud to announce an expansion of its partnership with Databricks by participating in Databricks’ newly launched Data Ingestion Network. A key component of this integration is leveraging the recently released Databricks COPY command for bulk ingest into Databricks Delta Lake using StreamSets for Databricks.

Let’s consider a simple example of ingesting accounts information from Salesforce and storing it in queryable format in a Databricks Delta Lake table.


Here are the steps for designing our dataflow pipeline:

  • Configure Salesforce origin to read (accounts) information
  • Configure Expression Evaluator processor to transform input data attribute Type
  • Configure Databricks Delta Lake destination to write the data to Databricks Delta Lake table


Databricks Ingestion Pipeline

Salesforce credentials will need to entered on Salesforce tab and the other configuration attribute of interest here on Query tab is SOQL Query which will retrieve account details from Salesforce.

SELECT Id, Name, Type, BillingStreet, BillingCity, BillingState, BillingPostalCode, BillingCountry, Website, PhotoUrl, AccountNumber, Industry, Rating, AnnualRevenue, NumberOfEmployees 
FROM Account 
Order By Id

Expressions Evaluator—Processor

Ingesting Salesforce Data into Databricks

Configuration attribute of interest is Field Expression that uses regular expression to remove redundant prefix text “Customer –” from account Type field.

${str:regExCapture(record:value('/Type'),'(.*) - (.*)',2)}

Databricks Delta Lake—Destination

With Databricks Runtime version 6.3 or later, you can use the Databricks Delta Lake destination in Data Collector version 3.16 and in future releases for the following bulk ingest and CDC use cases.

  • Bulk Ingest — In this case the Databricks Delta Lake destination uses the COPY command to load data into Delta Lake tables.
  • Change Data Capture — When processing CDC data, the Databricks Delta Lake destination uses the MERGE command to load data into Delta Lake tables.

In this blog, we’re focused on bulk ingestion so on Salesforce origin we have the following configuration:

  • Query Existing Data — Set to true
  • Subscribe for Notifications — Set to false

Salesforce data ingestion to Databricks

Configuration attributes of interest:

  • JDBC URL — The JDBC URL to connect to the Databricks cluster
  • Token — The user token to use to connect to the Databricks cluster
  • Auto Create Table — Enabling this attribute will auto-create the Databricks Delta Lake table if it doesn’t already exist

Preview Pipeline

Previewing the pipeline is a great way to see the transformations occurring on attribute values. See below the selected Expression Evaluator processor and before and after values of Type attribute.

Query Databricks Delta Lake

If everything looks good in preview mode, running the pipeline should bulk copy accounts information from Salesforce to Databricks Delta Lake.

Once the Delta Lake table is populated, you can start analyzing the data. For example, running the following query will give us insights into total revenue generated based on account ratings and types of accounts.

Total Revenue by Rating and Account Type

SELECT Rating, Type, format_number(SUM(AnnualRevenue),2) AS Total_Revenue
WHERE Rating is not null and Type is not null 
GROUP BY Rating, Type
