# Which issue does this PR close? - Closes #8523. # Rationale for this change One of the primary reasons the GeoParquet community was excited about first-class Parquet Geometry/Geography support was the built-in column chunk statistics (we had a workaround that involved adding a struct column, but it was difficult for non-spatial readers to use it and very difficult for non-spatial writers to write it). This PR ensures it is possible for arrow-rs to write files that include those statistics. # What changes are included in this PR? This PR inserts the minimum required change to enable this support (behind a feature flag). This also fixes a "bug" (if anybody had been using it to write Geospatial types, which is unlikely)...those types must not have page min/max statistics written. # Are these changes tested? They will be! (Work in progress) # Are there any user-facing changes? No, this is behind a newly invented feature flag. In the unlikely event anybody had been writing Geometry/Geography logical types, they would continue to not have geospatial statistics written. -- This is an automated message from the Apache Git Service.
