I have been able to successfully avoid bitmap allocation for the case where null handling is `INTERSECTION` and all input Datums have all valid values. One simple test case has been added for cast kernel, I would think adding such tests for all compute functions would be prudent. I did however encounter one unexpected error when in an existing unit test `TestCallScalarFunction.PreallocationCases`. At this moment, I am not sure why a modified context would change Datum kind. Please see the error message of test failure ``` /home/pradeep/gitroot/ArrowWorkspace/worktrees/15118/cpp/src/arrow/datum.cc:71: Check failed: (Datum::ARRAY) == (this->kind()) ``` This is triggered from line 789 of `exec_test.cc`. There is an identical test just few lines above where context argument isn't passed along and that runs fine. Any hints at what I am missing here is appreciated. Thank you! Command to run the specific test to see the problem on my branch is given below: ``` ./debug/arrow-compute-internals-test --gtest_filter=TestCallScalarFunction.PreallocationCases ``` assuming build type is `debug` @lidavidm @edponce -- This is an automated message from the Apache Git Service.
