Apache Spark reassigned SPARK-36992: ------------------------------------ Assignee: Apache Spark > Improve byte array sort perf by unify getPrefix function of UTF8String and > ByteArray > ------------------------------------------------------------------------------------ > > Key: SPARK-36992 > URL: https://issues.apache.org/jira/browse/SPARK-36992 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.3.0 > Reporter: XiDuo You > Assignee: Apache Spark > Priority: Major > > When execute sort operator, we first compare the prefix. However the > getPrefix function of byte array is slow. We use first 8 bytes as the prefix, > so at most we will call 8 times with `Platform.getByte` which is slower than > call once with `Platform.getInt` or `Platform.getLong`. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
