Subject [GitHub] spark pull request: [SPARK-8301][SQL] Improve UTF8String substring...
Date Wed, 17 Jun 2015 05:25:25 GMT
Github user chenghao-intel commented on the pull request:
    @tarekauel Glad to see the big improvement for the performance gain! I have some comments
on the API change, e.g. the `null` value checking, comparison with `null`, probably we'd better
not change its original behavior for `UTF8String`, seems behavior as `java.lang.String` does
will be reasonable to me, what do you think?
