gatekeeper.py

This module defines the Gatekeeper class, responsible for processing database queries.
The Gatekeeper utilizes a provided proxy to route and execute SQL queries.

Usage:
    1. Import the Gatekeeper class from this module.
    2. Create an instance of the Gatekeeper, passing a proxy as a parameter.
    3. Call the `process_request` method with the query type to initiate query processing.

Example:
    from gatekeeper import Gatekeeper
    from my_proxy_module import MyProxy

    # Create an instance of the proxy (MyProxy should be replaced with the actual proxy class)
    proxy_instance = MyProxy()

    # Create an instance of the Gatekeeper with the proxy
    gatekeeper = Gatekeeper(proxy_instance)

    # Process a write query
    gatekeeper.process_request('write')

Note:
    - The process_request method currently contains a sample SQL query for insertion.
      Modify the method and queries as needed for your specific use case.
