8. A method implemented by at least one processing device, the method comprising: obtaining a data file comprising a logic expression; executing application code that includes a plurality of executable components; in a first instance, while executing the application code: receiving a first query that does not include the logic expression and is not included in the data file; reading the logic expression from the data file, the logic expression identifying a first executable component of the application code and a second executable component of the application code; processing the first query using both the first executable component and the second executable component to determine a first logical result of the logic expression; and based on the first logical result of the logic expression, providing a first query result in response to the first query; and in a second instance, while continuing to execute the application code and without restarting the application code: receiving a second query that does not include the logic expression and is not included in the data file; reading the logic expression from the data file again and detecting that the logic expression no longer identifies the second executable component; responsive to detecting that the logic expression no longer identifies the second executable component, processing the second query using the first executable component and not the second executable component to determine a second logical result of the logic expression; and based on the second logical result of the logic expression, providing a second query result in response to the second query, wherein the application code is executed without interpreting or compiling the logic expression.
10. The method of claim 8 , further comprising selectively executing a service module of the application code based on a plurality of logical results of executing the application code, the plurality of logical results including the first logical result and the second logical result.
