Parquet Files
Read and write Parquet files
Parquet file format supports very efficient compression and encoding of column oriented data. This format enables compression schemes to be specified on a per-column level allowing efficient compression and encoding of data. To read and write Parquet files in MATLAB®, use the parquetread
and parquetwrite
functions. To read a collection of Parquet files, use parquetDatastore
. To conditionally filter and read data faster (Predicate Pushdown) from Parquet files, use rowfilter
.
For more information on the Parquet file format, see https://parquet.apache.org/
