sql编译代码时超过64kb导致编译失败,请问有啥办法绕过这个问题吗?尝试过把sql逻辑拆开成多个view,
但是sql逻辑优化的时候还是会合并到一起,无法绕过 Caused by: org.codehaus.janino.InternalCompilerException: Code of method "map(Ljava/lang/Object;)Ljava/lang/Object;" of class "ExpressionReducer$3674" grows beyond 64 KB at org.codehaus.janino.CodeContext.makeSpace(CodeContext.java:1009) at org.codehaus.janino.CodeContext.write(CodeContext.java:901) at org.codehaus.janino.UnitCompiler.writeShort(UnitCompiler.java:12195) at org.codehaus.janino.UnitCompiler.pushConstant(UnitCompiler.java:10660) at org.codehaus.janino.UnitCompiler.compileGet2(UnitCompiler.java:5553) at org.codehaus.janino.UnitCompiler.access$9300(UnitCompiler.java:215) at org.codehaus.janino.UnitCompiler$16.visitIntegerLiteral(UnitCompiler.java:4423) at org.codehaus.janino.UnitCompiler$16.visitIntegerLiteral(UnitCompiler.java:4394) at org.codehaus.janino.Java$IntegerLiteral.accept(Java.java:5442) at org.codehaus.janino.UnitCompiler.compileGet(UnitCompiler.java:4394) at org.codehaus.janino.UnitCompiler.fakeCompile(UnitCompiler.java:3719) at org.codehaus.janino.UnitCompiler.compileGetValue(UnitCompiler.java:5569) at org.codehaus.janino.UnitCompiler.compileGet2(UnitCompiler.java:5165) at org.codehaus.janino.UnitCompiler.access$9100(UnitCompiler.java:215) at org.codehaus.janino.UnitCompiler$16.visitMethodInvocation(UnitCompiler.java:4421) at org.codehaus.janino.UnitCompiler$16.visitMethodInvocation(UnitCompiler.java:4394) at org.codehaus.janino.Java$MethodInvocation.accept(Java.java:5062) at org.codehaus.janino.UnitCompiler.compileGet(UnitCompiler.java:4394) at org.codehaus.janino.UnitCompiler.compileGetValue(UnitCompiler.java:5575) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java:3781) at org.codehaus.janino.UnitCompiler.access$5900(UnitCompiler.java:215) at org.codehaus.janino.UnitCompiler$13.visitMethodInvocation(UnitCompiler.java:3760) at org.codehaus.janino.UnitCompiler$13.visitMethodInvocation(UnitCompiler.java:3732) at org.codehaus.janino.Java$MethodInvocation.accept(Java.java:5062) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java:3732) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java:2360) at org.codehaus.janino.UnitCompiler.access$1800(UnitCompiler.java:215) at org.codehaus.janino.UnitCompiler$6.visitExpressionStatement(UnitCompiler.java:1494) at org.codehaus.janino.UnitCompiler$6.visitExpressionStatement(UnitCompiler.java:1487) at org.codehaus.janino.Java$ExpressionStatement.accept(Java.java:2871) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java:1487) at org.codehaus.janino.UnitCompiler.compileStatements(UnitCompiler.java:1567) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java:1553) at org.codehaus.janino.UnitCompiler.access$1700(UnitCompiler.java:215) at org.codehaus.janino.UnitCompiler$6.visitBlock(UnitCompiler.java:1493) at org.codehaus.janino.UnitCompiler$6.visitBlock(UnitCompiler.java:1487) at org.codehaus.janino.Java$Block.accept(Java.java:2776) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java:1487) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java:2465) at org.codehaus.janino.UnitCompiler.access$1900(UnitCompiler.java:215) at org.codehaus.janino.UnitCompiler$6.visitIfStatement(UnitCompiler.java:1495) at org.codehaus.janino.UnitCompiler$6.visitIfStatement(UnitCompiler.java:1487) at org.codehaus.janino.Java$IfStatement.accept(Java.java:2947) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java:1487) at org.codehaus.janino.UnitCompiler.compileStatements(UnitCompiler.java:1567) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java:3388) at org.codehaus.janino.UnitCompiler.compileDeclaredMethods(UnitCompiler.java:1357) at org.codehaus.janino.UnitCompiler.compileDeclaredMethods(UnitCompiler.java:1330) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java:822) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java:432) at org.codehaus.janino.UnitCompiler.access$400(UnitCompiler.java:215) at org.codehaus.janino.UnitCompiler$2.visitPackageMemberClassDeclaration(UnitCompiler.java:411) at org.codehaus.janino.UnitCompiler$2.visitPackageMemberClassDeclaration(UnitCompiler.java:406) at org.codehaus.janino.Java$PackageMemberClassDeclaration.accept(Java.java:1414) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java:406) at org.codehaus.janino.UnitCompiler.compileUnit(UnitCompiler.java:378) ... 51 more -- Sent from: http://apache-flink.147419.n8.nabble.com/ |
这个问题需要更改CodeGen部分的代码,你可以把上述ExpressionReducer的问题补充到如下issue中,
我可以帮助一起fix. https://issues.apache.org/jira/browse/FLINK-20898 另外,辛苦也补充一个测试sql示例。 stgztsw <[hidden email]> 于2021年1月27日周三 下午6:10写道: > sql编译代码时超过64kb导致编译失败,请问有啥办法绕过这个问题吗?尝试过把sql逻辑拆开成多个view, >

这个限制不仅仅在janino这边,我们这边已经尝试去除了janino这边的64kb的限制,但是逻辑运行到jdk这边也出现了同样的限制。目前spark是通过spark.conf.set("spark.sql.codegen.wholeStage",false)来避免类似的问题,所以我觉得最好的方法是可以通过配置来限制一些SQL逻辑计划的优化,避免不同的view的逻辑合并到一起,这样就能通过将拆分sql来将逻辑拆分到不同的function中,从而避免一个类函数太大。
