   Thanks again @Dandandan for working on JIT! I hope I can have time to work with you on jit soon. 
   
   FWIW, one of our blockers is Cranelift has no ability to inline assembly, so it causes performance regression for columnar to row conversion (as recognized in https://github.com/apache/arrow-datafusion/pull/1975). A possible solution is to use LLVM instead of Cranelift because PostgreSQL and Impala have proved that inline is feasible in LLVM. I would pick it up if it's not taken already at the time.
