> When escaping / unescaping partition path part names, the existing logic incurs significant avoidable overhead by copying each character sequentially into a new StringBuilder even when no escaping/unescaping is necessary as well as using String.format to escape characters inside of the inner loop.
>  
> The included patch to improve the performance of these operations refactors two static method implementations, but requires no external API surface or user-visible behavior changes. This change is applicable and portable to a wide range of Hive versions from branch-0.6 onward when the initial method implementations were added.
