---------------------------------
> Use strings directly in rapidjson without conversion to char*
> -------------------------------------------------------------

> Key: IMPALA-13843
> URL: https://issues.apache.org/jira/browse/IMPALA-13843
> Project: IMPALA
> Issue Type: New Feature
> Reporter: Surya Hebbar
> Assignee: Surya Hebbar
> Priority: Major
>
> The RapidJSON library recalculates length of a StringRef each time when using
> char*, until null character.
> Within the codebase, many times we are converting from string->char* for
> RapidJSON.
> Instead with RAPIDJSON_HAS_STDSTRING, we can use strings directly, which
> contain the size, instead of recalculating or size declaration each time.
> This is efficient and a major convenience for DOM creation.
> This impacts large JSON profiles, where this is repeated multiple times.
