subotac opened a new pull request, #10572:
URL: https://github.com/apache/arrow-rs/pull/10572
# Which issue does this PR close?
- Closes #10534.
# Rationale for this change
`GeometryBounder::x()` calculates the candidate wraparound width using
`x_right.hi()`, although the returned interval starts at `x_right.lo()`.
This can underestimate the wraparound width and select looser bounds,
weakening row-group pruning.
# What changes are included in this PR?
Use `x_right.lo()` when calculating the wraparound width and add a
regression case where the Cartesian bounds are narrower.
# Are these changes tested?
Yes:
- `cargo test -p parquet-geospatial`
- `cargo +stable fmt --all -- --check`
- `cargo clippy -p parquet-geospatial --all-targets --all-features -- -D
warnings`
- `cargo clippy --workspace --all-targets --all-features -- -D warnings`
- `git diff --check`
# Are there any user-facing changes?
Yes. Newly computed geospatial column statistics may use tighter Cartesian
bounds when appropriate. There are no public API changes.
