> > My guess is that some of the new slowdown / less predictability is due to many more `Box`es (and thus allocations) -- I suggest we reconsider Boxing frequently used structures (like Column in alias, for example) -- that might make Expr larger but would result in less allocator pressure > > Thank you @alamb , this is a very good point, let me try this and to see the benchmark result! @alamb Updated in latest PR, only small change now. -- This is an automated message from the Apache Git Service.
