Some fields, like formula queries or nested summary fields, can recalculate hundreds of millions of cells on every request, even when the underlying data hasn’t changed. Field caching lets you recalculate these fields only when data in your app changes—improving performance. Use your business case knowledge to determine which of your apps don't need to recalculate a specific field on every request. Field caching is available for [eligible summary and formula fields](/v1/docs/field-caching#eligible-fields-for-caching) on the Enterprise plan with the Advanced Performance Pack. ## Eligible fields for caching Field caching is available for: - Summary fields that don’t contain user permissions or filters, and don’t depend on fields that do - Formula fields that do not contain user filtering or formula queries ## Turn on field caching To turn on caching for eligible summary or formula fields: 1. Open the **Field properties** of a summary or formula field in your table. 2. Go to **Advanced > Performance** and check **Evaluate this field only when data has changed**.
