Reynold Xin updated SPARK-8829:
-------------------------------
    Description: 
This is an umbrella ticket for various improvements to DataFrame and SQL expression performance.

These expressions can be found in the org.apache.spark.sql.catalyst.expressions package.

Note that I also created a separate ticket for improving regular expression performance potentially
using joni (SPARK-9213).
