Composite Keys in Data Streams: When working with data streams in Salesforce Data Cloud, there may be situations where a primary key is not available. In such cases, creating a composite key from multiple fields ensures unique identification of records.

Formula Functions: Salesforce provides several formula functions to manipulate and combine data fields. Among them, the CONCAT function is used to combine multiple strings into one.

Creating Composite Keys: To create a composite key using CONCAT, a consultant can combine the values of Customer Region and Customer Identifier into a single unique identifier.

Example Formula: CONCAT(Customer_Region, Customer_Identifier)

Data Streams and DLOs: In Salesforce Data Cloud, data streams are used to ingest data, which is then stored in Data Lake Objects (DLOs).

Deletion Considerations: Before deleting a data stream, it's crucial to consider the dependencies and usage of the underlying DLO.

Data Transform Usage:

Impact of Deletion: If the underlying DLO is used in a data transform, deleting the data stream will affect any transforms relying on that DLO.

Dependency Check: Ensure that the DLO is not part of any active data transformations or processes that could be disrupted by its deletion.

Dependencies in Data Cloud:

Before disconnecting a data source, all dependencies must be removed to prevent data integrity issues.

Ensuring High Availability and Fault Tolerance:

High availability refers to systems that are continuously operational and accessible, while fault tolerance is the ability to continue functioning in the event of a failure.
