Jinfeng Ni reassigned DRILL-4715: --------------------------------- Assignee: Jinfeng Ni > Java compilation error for a query with large number of expressions > ------------------------------------------------------------------- > > Key: DRILL-4715 > URL: https://issues.apache.org/jira/browse/DRILL-4715 > Project: Apache Drill > Issue Type: Bug > Components: Execution - Codegen > Reporter: Jinfeng Ni > Assignee: Jinfeng Ni > Fix For: 1.8.0 > > > The following query would hit compilation error, when Drill generates and > compiles the run-time code. > Q1 : > {code} > select expr1, expr2, expr3, ...., exprN > from table > {code} > In Q1, expr1, expr2, ..., exprN are non-trivial expression (in stead of > simply column reference), and N is big enough, then the run-time generated > code may have a method which goes beyond the 64k limit imposed by JVM. > This seems to be a regression from DRILL-3912 (Common subexpression > elimination). CSE tries to put as many expressions in one block as possible, > to detect and eliminate as many CSE as possible. However, this implies we may > end up with big method with compilation error. > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
