You’re designing a file upload process that integrates with an external document management system.

While Appian and the integration technically support 1 GB file uploads, handling such large files during interactive sessions can negatively impact application performance, user experience, and resource utilization.

A better approach is to request that the business allow these files to be uploaded asynchronously (e.g., overnight batch process), by temporarily storing them (e.g., in a staging table or folder) and processing them when system load is lower. This makes the process more performant and reliable without straining Appian or the external system.
