[jira] [Created] (SPARK-14577) spark.sql.codegen.maxCaseBranches config option

Reynold Xin created SPARK-14577:
-----------------------------------

             Summary: spark.sql.codegen.maxCaseBranches config option
                 Key: SPARK-14577
                 URL: https://issues.apache.org/jira/browse/SPARK-14577
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Reynold Xin


We currently disable codegen for CaseWhen if the number of branches is greater than 20 (in CaseWhen.MAX_NUM_CASES_FOR_CODEGEN). It would be better if this value is a non-public config defined in SQLConf.
