Pull request overview
This PR introduces an experimental “patched array” pathway for FastLanes BitPacked data, enabling legacy BitPacked-with-interior-patches payloads to deserialize as a Patched wrapper, and wiring the same mode into compression + file encoding allowlists.
Changes:
- Add a BitPacked deserialization plugin that rewrites interior patches into a
Patchedwrapper whenVORTEX_EXPERIMENTAL_PATCHED_ARRAYis set. - Update integer bitpacking compression to emit
Patched(instead of interior patches) in experimental mode and update file allowed-encodings accordingly. - Enable the experimental mode in benchmark GitHub Actions workflows via env var.

Summary
Part of roll out of Patched array. This PR adds a new environment variable,
VORTEX_EXPERIMENTAL_PATCHED_ARRAY.When the env var is set
BitPackedarray with interior patches will be decoded as aPatchedarray wrapping aBitPackedwith no interior patchesThis allows us to do some more soak testing of the encoding before we switch it to be the default.
Testing
On a previous commit in this PR, I've setup the benchmarks to run with the experimental Patched encoding enabled, the benchmark results all seem within the margin of error. The file sizes are generally the same but in the worst case, 2-3% larger.
