# Which issue does this PR close? - Closes #NNN. # Rationale for this change Just improves performance, I was profiling some things downstream and got curious about how it works. # What changes are included in this PR? The main idea is to use a two-pass approach : 1. Compute byte offsets and collects (start, end) byte ranges 2. Copy byte data via raw pointer writes (`copy_byte_ranges`) This PR also reduces the branching from 4 (one for each nullability combination) to only two. # Are these changes tested? Existing tests # Are there any user-facing changes? None -- This is an automated message from the Apache Git Service.
