Marco Gaido created SPARK-22520: ----------------------------------- Summary: Support code generation also for complex CASE WHEN Key: SPARK-22520 URL: https://issues.apache.org/jira/browse/SPARK-22520 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 2.3.0 Reporter: Marco Gaido Priority: Minor
Code generation is disabled for CaseWhen when the number of branches is higher than {{spark.sql.codegen.maxCaseBranches}} (which defaults to 20). This was done in SPARK-13242 to prevent the well known 64KB method limit exception. This tickets proposes to support code generation also in those cases (without causing exceptions of course). As a side effect, we could get rid of the {{spark.sql.codegen.maxCaseBranches}} configuration. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
