A method of generating an optimized executable configuration query engine is disclosed. A set of one or more immutable configuration parameters associated with a configurable service or a configurable application is received. At least a portion of a set of configuration data in a configuration database and at least a portion of the set of one or more immutable configuration parameters are transformed into a set of data and code in a compiler-readable format. An optimized subset of the set of configuration data in the configuration database is selected based at least in part on the set of one or more immutable configuration parameters. An optimized executable configuration query engine is generated based at least in part on the set of one or more immutable configuration parameters, wherein the optimized executable configuration query engine serves configuration data from the selected optimized subset of the set of configuration data.
