----------------------------------
Summary: Improve UTF8String fromString()/toString()/numChars()
performance when strings are ASCII
Key: SPARK-27841
URL: https://issues.apache.org/jira/browse/SPARK-27841
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Josh Rosen
Assignee: Josh Rosen
UTF8String's fromString(), toString(), and numChars() methods are performance
hotspots. For strings which consist entirely of ASCII characters we can make
performance optimizations which significantly reduce memory allocation and
copying, greatly improving performance for many common workloads.
