# openstreetmap_h3
OSM planet dump high performance data loader. Transform OpenStreetMap World/Region PBF dump into partitioned by [H3 regions](https://h3geo.org) PostGIS pgsnapshot (lossless) OSM schema representation and/or into ArrowIPC/Parquet dumps [with schema](https://github.com/igor-suhorukov/openstreetmap_h3/tree/master/src/main/resources/schema). "columnar_storage" option activate Citus columnar storage in PostgreSQL to speedup aggregation queries.
More details in [blog posts](https://habr.com/en/post/717408)...

## Apache Parquet export
Parquet export activated with "-arrow_format PARQUET" command line parameter.
OpenStreetMap H3 also allows you to convert data to Apache Parquet and process it in Hadoop and Apache Spark/Sedona. In this project, it allows you to do the same as osm-parquetizer but with additional data and collected geo coordinates for ways, as well as enriched h3 geo indexes. The files are successfully uploaded to the DuckDB Geo extension, I checked this and I will tell you the details in the publication.
