## Which issue does this PR close? - Closes #18300 ## Rationale for this change As laid out in the issue, this improves internal checks by testing an assumed invariant, instead of silently nulling data on error. The cost is a single null check on a column with a number of entries dependent on the number of partitions, not the data itself. ## What changes are included in this PR? * Adds a null check to the second column of `merge_batch` of both `FIRST_VALUE` and `LAST_VALUE`. ## Are these changes tested? Tests are included. ## Are there any user-facing changes? Hopefully not. -- This is an automated message from the Apache Git Service.
