Speculative execution for regular expressions

One or more non-transitory computer-readable media storing a set of instructions, wherein the set of instructions includes instructions, which when executed by one or more hardware processors, cause:

• receiving first string input data and first regex pattern data, the first string input data indicating one or more first strings with which a first regex pattern, of the first regex pattern data, is to be matched;
• determining one or more properties of the one or more strings of the first string input data;
• based on the one or more properties of the first string input data, generating one or more first descriptors for the first string input data;
• based on the one or more first descriptors, validating a particular existing assertion for selection of a first execution logic from a plurality of alternative execution logics to, at least in part, evaluate the first regex pattern on the one or more first strings by a particular regex engine that includes the plurality of alternative execution logics;
• loading the first execution logic for evaluating the first regex pattern on the one or more first strings;
• based on validating the particular existing assertion for selecting the first execution logic, evaluating the first regex pattern on the one or more first strings to yield result data of matching the first regex pattern to the one or more first strings using, at least in part, the first execution logic from the plurality of alternative execution logics of the particular regex engine.
