Marco Gaido created SPARK-22215: ----------------------------------- Summary: Add a configuration parameter to set max size for generated classes Key: SPARK-22215 URL: https://issues.apache.org/jira/browse/SPARK-22215 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 2.2.0 Reporter: Marco Gaido
SPARK-18016 introduced an arbitrary threshold for the size of a generated class (https://github.com/apache/spark/blob/83488cc3180ca18f829516f550766efb3095881e/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/codegen/CodeGenerator.scala#L286). This value is hardcoded. Since this is just a guess, in some cases making it smaller can help avoiding the error of exceeding the maximum number of entries in the Constant Pool. Then, I suggest to introduce a new configuration parameter, which defaults to the previous value, but it allows to set this to a smaller one if needed. -- 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
