Consider a situation where you are building a Flask API that needs to handle large file uploads. What steps would you take to ensure that the file upload process is efficient and doesn't strain the server resources?

To ensure efficient handling of large file uploads in a Flask API, it's important to use a streaming approach for file uploads. This allows the server to process files in smaller, manageable chunks, reducing the strain on server resources. Handling file uploads in the main application thread can lead to performance issues, and proper authentication and setting file size limits are essential for security and resource management.
