Is it possible to read and write parquet files from one folder to another folder in s3 without converting into pandas using pyarrow.
Here is my code:
import pyarrow.parquet as pq
import pyarrow as pa
import s3fss3 = s3fs.S3FileSystem()bucket = 'demo-s3'pd = pq.ParquetDataset('s3://{0}/old'.format(bucket), filesystem=s3).read(nthreads=4).to_pandas()
table = pa.Table.from_pandas(pd)
pq.write_to_dataset(table, 's3://{0}/new'.format(bucket), filesystem=s3, use_dictionary=True, compression='snappy')
