> Despite belonging to the latter group, these functions still undergo JIT compilation before they can be utilized. Right. But that function just calls into `re2`, and `re2` won't be JIT-compiled (i.e. the code won't be specialized for the particular regular expression). You're just JIT-compiling the stub, not the actual workhorse. That said, I don't object this either if this makes Gandiva somehow easier to use. It's just that using Gandiva for regular expression matching will not bring any performance improvements over calling `re2` directly (for example using https://arrow.apache.org/docs/cpp/compute.html#containment-tests). -- This is an automated message from the Apache Git Service.
