Armin 73d9067226 [SPARK-21967][CORE] org.apache.spark.unsafe.types.UTF8String#compareTo Should Compare 8 Bytes at a Time for Better Performance ... ## What changes were proposed in this pull request? * Using 64 bit unsigned long comparison instead of unsigned int comparison in `org.apache.spark.unsafe.types.UTF8String#compareTo` for better performance. * Making `IS_LITTLE_ENDIAN` a constant for correctness reasons (shouldn't use a non-constant in `compareTo` implementations and it def. is a constant per JVM) ## How was this patch tested? Build passes and the functionality is widely covered by existing tests as far as I can see. Author: Armin <me@obrown.io> Closes #19180 from original-brownbear/SPARK-21967.		2017-09-16 09:18:13 +01:00
