Reading and Writing Apache Parquet
Reading and Writing Apache Parquet#
Similar to dask-dataframe, dask-geopandas supports reading and writing Apache Parquet files.
As outlined in :doc:
guide/spatial-partitioning, dask-geopandas can spatially partition datasets. These partitions are
persisted in the parquet files.
By default, reading these spatial partitions requires opening every file and checking its spatial extent. This can be a
bit slow if the parquet dataset is made up of many individual partitions. To disable loading the spatial partitions,
gather_spatial_partitions=False when reading the file:
ddf = dask_geopandas.read_parquet("...", gather_spatial_partitions=False) ddf.spatial_partitions # None
