What is Appian best practice for calling a query on your interface?

• A. Precompute each time
• B. Call the query once on a local variable
• C. Call the query multiple times in components
• D. Call the query at the page level only

Answer: (B)

Keep data calls efficient by fetching once and reusing the result. In Appian interfaces, querying data can be relatively expensive, and re-running the same query from multiple components or on every render can lead to extra network calls and slower UI updates. Storing the query result in a local variable means you fetch data a single time for the interface instance and then reference that cached data wherever needed, which improves performance and consistency. If you need to refresh, you can trigger a refresh of that local variable rather than issuing multiple calls from different parts of the interface.
