Phillip Cloud commented on ARROW-2224:
--------------------------------------
The original implementation used C++ to implement a handwritten parser, but it
quickly got complex once we needed to support integers with exponential
notation. Maybe the complexity of dealing with boost is greater than the
complexity of debugging a handwritten parser, in which case it would be worth
it to reimplement it without a regular expression.
> [C++] Replace boost regex usage with libre2
