@zml1206, thanks for your pr! What's Velox's current behavior for this case? Will Velox interrupt with some error?

The error reported by velox is the same as the error reported by gluten in the issue, "bad optional access".

https://github.com/facebookincubator/velox/blob/f33b40da09441d542f32ee9ed9fb2e340d3c2a75/velox/functions/prestosql/window/LeadLag.cpp#L33
The error should be reported here. @philo-he

Looks good to me! Assume the foldable input is rarely used. So it has low priority. It's ok to firstly let Gluten fall back for that.

Thank you @philo-he
Yes, although vanilla Spark supports foldable input of lag/lead, there is almost no usage scenario in this case, and the values ​​obtained are all null or default.
