Can Query Helper leverage Spark?

Dear Community,

could someone tell me how the Query Helper Processor works internally or more specifically whether it is able to leverage Spark for parallel computations?
My specific use case is: I have a (potentially huge, millions of rows) table with key-value pairs. I want to apply queries which perform an RLIKE operation on the values, that means they will evaluate whether the values fit a regular expression. There can be multiple queries depending on the amount of regular expressions that are fed into the workflow via another input and can be quite a few as well (expected in a two-digit range).
Now my question more specifically: Can the Query Helper perform those queries in parallel so that all (or at least some) RLIKE queries are performed in parallel?
