----------------------------------------
Summary: Writing covering column metadata to GeoParquet files
Key: SEDONA-627
URL: https://issues.apache.org/jira/browse/SEDONA-627
Project: Apache Sedona
Issue Type: New Feature
Reporter: Kristin Cowalcijk
GeoParquet spec 1.1 added a column {{covering}} metadata, it specifies a struct
column containing bounding boxes to accelerate spatial queries. The GeoParquet
writer of Apache Sedona could support this metadata in 2 ways:
1. The DataFrame being written already has covering columns, GeoParquet writer
only write proper covering metadata to geoparquet metadata.
2. Automatically write bounding boxes to covering columns.
