Zuora to Redshift

This page provides you with instructions on how to extract data from Zuora and load it into Redshift. (If this manual process sounds onerous, check out Stitch, which can do all the heavy lifting for you in just a few clicks.)

What is Zuora?

Zuora provides billing automation, commerce, and analytics applications for businesses with a service subscription model.

Getting data out of Zuora

Zuora provides both a REST API and an older SOAP API that let you extract information from its system. If, for example, you wanted to retrieve a list of accounting codes, you could use the REST API to call GET /rest/v1/accounting-codes.

Sample Zuora data

The Zuora API returns data in JSON format. For example, the result of a call to retrieve a list of accounting codes might look like this:

{
    "accountingCodes": [
        {
            "id": "e20b0747478025a10147816ba1c20097",
            "name": "Accounts Receivable",
            "type": "AccountsReceivable",
            "glAccountName": null,
            "glAccountNumber": null,
            "notes": null,
            "category": "Assets",
            "status": "Active",
            "CustomField__c": null,
            "createdOn": "2017-07-29 02:20:20",
            "createdBy": "e20b074746ec48f40147140f51e30a1a",
            "updatedOn": "2017-07-29 02:20:20",
            "updatedBy": "e20b074746ec48f40147140f51e30a1a"
        },
        {
            "id": "e20b0747478025a10147816ba21900a0",
            "name": "Discounts",
            "type": "SalesDiscounts",
            "glAccountName": null,
            "glAccountNumber": null,
            "notes": null,
            "category": "Revenue",
            "status": "Inactive",
            "CustomField__c": null,
            "createdOn": "2017-07-29 02:20:20",
            "createdBy": "e20b074746ec48f40147140f51e30a1a",
            "updatedOn": "2017-09-27 22:11:07",
            "updatedBy": "e20b074746ec48f40147140f51e30a1a"
        }
    ],
    "success": true
}

Preparing Zuora data

If you don't already have a data structure in which to store the data you retrieve, you'll have to create a schema for your data tables. Then, for each value in the response, you'll need to identify a predefined datatype (INTEGER, DATETIME, etc.) and build a table that can receive them. The source API documentation should tell you what fields are provided by each endpoint, along with their corresponding datatypes.

Complicating things is the fact that the records retrieved from the source may not always be "flat" – some of the objects may actually be lists. This means you'll likely have to create additional tables to capture the unpredictable cardinality in each record.

Loading data into Redshift

Once you have identified all of the columns you will want to insert, you can use the CREATE TABLE statement in Redshift to create a table that can receive all of this data.

With a table built, it may seem like the easiest way to migrate your data (especially if there isn't much of it) is to build INSERT statements to add data to your Redshift table row by row. If you have any experience with SQL, this will be your gut reaction. But beware! Redshift isn't optimized for inserting data one row at a time. If you have a high volume of data to be inserted, you would be better off loading the data into Amazon S3 and then using the COPY command to load it into Redshift.

Keeping Zuora data up to date

At this point you've coded up a script or written a program to get the data you want and successfully moved it into your data warehouse. But how will you load new or updated data? It's not a good idea to replicate all of your data each time you have updated records. That process would be painfully slow and resource-intensive.

Instead, identify key fields that your script can use to bookmark its progression through the data and use to pick up where it left off as it looks for updated data. Auto-incrementing fields such as updated_at or created_at work best for this. When you've built in this functionality, you can set up your script as a cron job or continuous loop to get new data as it appears in Zuora.

And remember, as with any code, once you write it, you have to maintain it. If Zuora modifies its API, or the API sends a field with a datatype your code doesn't recognize, you may have to modify the script. If your users want slightly different information, you definitely will have to.

Other data warehouse options

Redshift is great, but sometimes you need to optimize for different things when you're choosing a data warehouse. Some folks choose to go with Google BigQuery, PostgreSQL, or Snowflake, which are RDBMSes that use similar SQL syntax, or Panoply, which works with Redshift instances. If you're interested in seeing the relevant steps for loading data into one of these platforms, check out To BigQuery, To Postgres, To Snowflake, and To Panoply.

Easier and faster alternatives

If all this sounds a bit overwhelming, don’t be alarmed. If you have all the skills necessary to go through this process, chances are building and maintaining a script like this isn’t a very high-leverage use of your time.

Thankfully, products like Stitch were built to solve this problem automatically. With just a few clicks, Stitch starts extracting your Zuora data via the API, structuring it in a way that is optimized for analysis, and inserting that data into your Redshift data warehouse.
