@cloud-fan Could you take a look at this followup to improve the primitive array with nulls issue. Thanks! |

Thank you for making a PR, @gene-db .
- Could you provide a test case to validate your contribution and to prevent any future regression at this area?
- I'd like to recommend to use
[SQL]in SQL module PR title next time.
Yes, the previous PR added many tests in this area, to make sure it is correct. The reason I am updating in this PR is to go back to using primitive arrays (and still produce correct results with the tests), which are faster than the object ones.
Ok, I will add the appropriate module name next time. Thanks! |

…when nulls exist ### What changes were proposed in this pull request? This is a followup to #46254 . Instead of using object arrays when nulls are present, continue to use primitive arrays when appropriate. This PR sets the null bits appropriately for the primitive array copy. Primitive arrays are faster than object arrays and won't create unnecessary objects. ### Why are the changes needed? This will improve performance and memory usage, when nulls are present in the `ColumnarArray`. ### Does this PR introduce _any_ user-facing change? This is expected to be faster when copying `ColumnarArray`. ### How was this patch tested? Existing tests. ### Was this patch authored or co-authored using generative AI tooling? No. Closes #46372 from gene-db/primitive-nulls. Authored-by: Gene Pang <gene.pang@databricks.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com> (cherry picked from commit bf2e254) Signed-off-by: Wenchen Fan <wenchen@databricks.com>
