Integrating Zero-Copy Data Pipelines into AppExchange Products via Salesforce Data Cloud

For an AppExchange product, getting access to customer data can become complicated pretty quickly.

We are familiar with The traditional approach where we pull data from an external system, transform it, move it into Salesforce or another application, and then keep the copy synchronized. It works, but as data volumes grow and customers add more systems, the pipeline becomes another thing to maintain.

What if the application could work with external data without creating another copy of it?

That is where zero-copy integration becomes interesting. Salesforce Data Cloud, now officially called Data 360, supports zero-copy data federation, allowing external data to be accessed without physically duplicating it in Data 360. Salesforce positions zero-copy as a way to work with data across external platforms without the traditional process of moving and copying it. 

For teams building Salesforce AppExchange development solutions, this opens up an interesting architectural option. Now, instead of designing every integration around moving data, an AppExchange product can be designed to work with data where it already lives.

So in this blog, we explore how an AppExchange product can incorporate external data into Salesforce Data Cloud using zero copy data integration. 

What Is Zero-Copy Data in Salesforce Data Cloud?

Zero copy is based on a simple idea that the data does not always need to be moved to the platform that needs to use it.

With traditional integration, external data is extracted, transformed and ingested into Salesforce or another destination. The destination then works with its own copy of that data.

With  zero-copy data federation, the external data stays in its source system while Data 360 accesses it through a supported connection. Salesforce supports both query and file federation, depending on the external source and connector. 

The difference can be simplified as:

Traditional integration:
External data → ETL/API pipeline → Salesforce/Data Cloud → AppExchange product

Zero-copy integration:
External data → Zero-copy federation → Data Cloud → AppExchange product

With live query federation, Data 360 can query the external data when it is needed rather than persisting the data in Data 360. Salesforce also provides caching options for certain query federation scenarios where reducing query latency is important. 

How to Integrate Zero-Copy Data into AppExchange Products via Salesforce Data Cloud

The process starts with the external data source.

Consider an AppExchange application that needs transaction information stored in a cloud data warehouse, while customer and account information already exists in Salesforce.

Instead of building a separate pipeline to copy the transaction data into Salesforce, the external source can be connected to Data 360 through a supported zero-copy federation connection.

The architecture can look like this:

External Data Source → Zero-Copy Federation → Data 360 → AppExchange Product

Salesforce's documented setup involves planning the data use case, establishing the external connection, creating a data stream and selecting the required objects and fields. The external data can then be mapped to the Data 360 data model for downstream use. 

For the AppExchange product, the important part is what happens after that connection is established.

The application can work with relevant Salesforce and external data without requiring the ISV to maintain a separate replicated dataset simply to make that information available.

Why Use Zero Copy for an AppExchange Product?

The biggest advantage is that you may not need to move and maintain data that already exists somewhere else.

In AppExchange product development, that can reduce the need for:

• Duplicate datasets

• Additional synchronization processes

• Data movement pipelines

• Maintaining replicated customer information

• Managing another copy that can become outdated

It can also help an application work with data that customers already maintain in their existing data platforms.

This matters for ISVs because customers rarely have identical technology environments. One may have transaction data in Snowflake, another in Databricks or BigQuery, while another may have information distributed across multiple systems.

A zero-copy architecture gives the product another option: access the required data through the Salesforce data layer instead of assuming every dataset has to be copied into the application.

Salesforce has also extended zero-copy capabilities to Data Kits, which ISVs and data providers can package and distribute through AppExchange. These can allow customers to access partner datasets through zero-copy integrations. ( Source: Salesforce)

For an AppExchange development company, this creates opportunities to design products that work with distributed enterprise data without making data replication the default architecture.

Does Zero Copy Replace Traditional Data Integration?

No. Zero copy is another option, not a replacement for every data pipeline or ingestion strategy.

There are still situations where bringing data into Salesforce or Data 360 makes more sense. An application may require extensive transformation, persistent historical data, predictable local performance or capabilities that aren't supported through federation.

The choice depends on what the application actually needs to do with the data.

An AppExchange development company may even use both approaches. Frequently used or business-critical data could be ingested, while large external datasets that only need to be accessed when required could remain in their source environment.

The goal isn't to eliminate data movement completely. It is to avoid moving data when moving it doesn't provide enough value to justify the additional complexity.

What Should AppExchange Developers Consider?

For an AppExchange development company, implementing zero copy isn't simply about connecting an external data source.

The product architecture still needs to consider 

• supported data sources, data mapping, permissions, security, query performance and how the application consumes the external data.

• Data modeling is particularly important. External data needs to be mapped appropriately so that it can work with the relevant Data 360 capabilities. 

• Performance also needs attention because zero copy does not automatically make external queries faster or remove the compute requirements of the source system.

• There are also platform-specific limitations to consider. The right approach depends on the data source, workload and the capabilities the AppExchange product needs to provide.

Conclusion

Zero-copy changes a basic assumption in AppExchange product development: external data doesn't always have to be moved before an application can use it.

For the right use cases, Salesforce Data Cloud's zero-copy capabilities can help AppExchange products access external data while reducing unnecessary replication and synchronization.

At Synexc, we approach Salesforce AppExchange development with this same architectural mindset. As a Salesforce consulting partner and an AppExchange ISV, we look at the product, its data sources and integration requirements before deciding how data should be connected and consumed.
