Validating predicate-based filters used in asynchronous messaging systems

A non-transitory machine-readable medium storing one or more sequences of instructions for validating predicate-based filters, wherein execution of said one or more instructions by one or more processors contained in a digital processing system cause said digital processing system to perform the actions of:

• identifying a predicate-based filter sought to be validated;
• parsing said predicate-based filter to determine a set of element identifiers contained in said predicate-based filter;
• generating a payload with each of said set of element identifiers assigned to a corresponding value;
• executing said predicate-based filter against said payload;
• and
• indicating that said predicate-based filter is valid if a status of said executing is a success, and is invalid otherwise.

A digital processing system comprising:

• a random access memory (RAM) to store instructions for validating predicate-based filters;
• and
• one or more processors to retrieve and execute the instructions, wherein execution of the instructions causes the digital processing system to perform the actions of:
• identifying a predicate-based filter sought to be validated;
• parsing said predicate-based filter to determine a set of element identifiers contained in said predicate-based filter;
• generating a payload with each of said set of element identifiers assigned to a corresponding value;
• executing said predicate-based filter against said payload;
• and
• indicating that said predicate-based filter is valid if a status of said executing is a success, and is invalid otherwise.
