DESCRIPTION:MapboxVectorTiles have changed the geospatial ecosystem. Vector
  data distribution has become more efficient\, map rendering has moved fro
 m server-side to client-side\, map styling has become more common. But doe
 s that mean we no longer need raster tiles? No. Raster tiles still matter.

DESCRIPTION:GeoParquet is a file format based on Apache Parquet for efficie
 nt storage of large geospatial datasets. Well-sorted Parquet achieves bett
 er compression and better query performance. However\, it is not enough fo
 r streaming features with acceptable performance. To address this\, I adde
 d hierarchical dimension for sorting and achieved better results.
