Presto使用了一个基于ASM的字节码生成工具airlift-bytecode（facebook内部库）来进行字节码的构建

Spark 和 Flink 都是使用 Janino 来做codeGen的，
Presto是使用airlift-bytecode

// org.apache.flink.table.runtime.generated.CompileUtils#doCompile
private static <T> Class<T> doCompile(ClassLoader cl, String name, String code) {
		checkNotNull(cl, "Classloader must not be null.");
		CODE_LOG.debug("Compiling: {} \n\n Code:\n{}", name, code);
		SimpleCompiler compiler = new SimpleCompiler();
		compiler.setParentClassLoader(cl);
		try {
			compiler.cook(code);
		} catch (Throwable t) {
			System.out.println(addLineNumber(code));
			throw new InvalidProgramException(
				"Table program cannot be compiled. This is a bug. Please file an issue.", t);
		}
		try {
			//noinspection unchecked
			return (Class<T>) compiler.getClassLoader().loadClass(name);
		} catch (ClassNotFoundException e) {
			throw new RuntimeException("Can not load class " + name, e);
		}
	}
