Understand Apex Cursors To Improve SOQL Performance

Apex Cursors are a new beta feature in Salesforce Summer ’24 release that allows you to work with large datasets retrieved using SOQL queries. Unlike SOQL which returns the entire dataset at once, Cursors retrieve data in manageable chunks, improving performance and memory usage.

Cursors provide some advantages over Batch Apex, such as:

🛎️ Forward and backward navigation within the results.
🛎️ Ability to be chained in a series of queueable Apex jobs.

Cursor processing occurs within a single transaction, ensuring data consistency. Cursors are an alternative to batch Apex and address some of batch Apex’s limitations. Cursors are also more powerful because they can be used in a chain of queueable Apex jobs. In this video, I am explaining this new feature with a sample code snippet
