sfarrow: 'sfarrow': An R package for reading/writing simple feature...
In sfarrow: Read/Write Simple Feature Objects ('sf') with 'Apache' 'Arrow'
Description
Simple features are a popular, standardised way to create spatial vector data
with a list-type geometry column. Parquet files are standard column-oriented
files designed by Apache Arrow (https://parquet.apache.org/) for fast
read/writes. sfarrow is designed to support the reading and writing of
simple features in sf objects from/to Parquet files (.parquet) and
Feather files (.feather) within R. A key goal of sfarrow is to
support interoperability of spatial data in files between R and
Python through the use of standardised metadata.
Metadata
Coordinate reference and geometry field information for sf objects are
stored in standard metadata tables within the files. The metadata are based
on a standard representation (Version 0.1.0, reference:
https://github.com/geopandas/geo-arrow-spec). This is compatible with
the format used by the Python library GeoPandas for read/writing
Parquet/Feather files. Note to users: this metadata format is not yet stable
for production uses and may change in the future.

Group at the University of Southampton(https://www.worldpop.org/).
