Frank McQuillan commented on MADLIB-984:
----------------------------------------
I'd suggest we do this before any other Path phase 2 stories since it will
simplify the code base and make it easier for developers to add subsequent
features to path.
> Path - refactor regex pattern match into cpp

> Key: MADLIB-984
> URL: https://issues.apache.org/jira/browse/MADLIB-984
> Project: Apache MADlib
> Issue Type: New Feature
> Components: Module: Utilities
> Reporter: Frank McQuillan
> Assignee: Xiaocheng Tang
> Fix For: v1.9.1
>
>
> The UDF to be implemented will obtain the matching indices in sym_str, which
> is in turn used to filter {match_to_row_id} for matched rows.
> This implementations pipeline operations directly in {matched_partitions}
> and remove the need of creating and joining two extra tables/views
> {length_of_matches} and {length_of_between_matches}.
> Boost.Regex can be helpful for implementing the proposed UDF:
