Wenchen Fan reassigned SPARK-22520: ----------------------------------- Assignee: Marco Gaido > 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 > Assignee: Marco Gaido > Priority: Minor > Fix For: 2.3.0 > > > 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
