> Project: Hive
> Issue Type: Improvement
> Components: Hive
> Affects Versions: All Versions
> Reporter: James Petty
> Priority: Minor
> Labels: pull-request-available
> Attachments: HIVE-26685.1.patch

> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
