input: Write a function to optimize a Flask application for efficient performance. The function should implement methods like using Redis for caching, uWSGI and gunicorn as WSGI servers, Flask-Compress for compression, and thread-local objects for performance. The function should also ensure the use of model methods instead of direct SQL queries and prefer query parameters in URLs over plain parameters.

      app = Flask(__name__)

      def process_request(endpoint):
          # Performance optimization
          # Use Redis for caching session and query performance
          # Use uWSGI for Python applications
          # Use gunicorn as WSGI server
          # Use Flask-Compress extension for compression
          # Use global variables where applicable
          # Don't use sql queries directly, always use model methods
          # Use query parameter in URLs instead of plain parameters
          # Use thread-local objects for performance
  
          # Your code here
