Luis Morales commented on ARROW-14930:
--------------------------------------
just as a reference... awsdatawrangler works perfectly, with methods like:
wr.s3.list_objects(path='s3://dasynth/parquet', boto3_session=sesion)
returning objects (parquet files)
for chunk in wr.s3.read_parquet('s3://dasynth/parquet/taxies/2019/',
dataset=True, boto3_session=sesion, use_threads=True, chunked=True):
chunks+=1
my_second_filter = lambda x: True if x["payment_type"].startswith("2") and
x["month_year"].startswith("2019-06") else False
for chunk in wr.s3.read_parquet(path="s3://dasynth/parquet/taxies/2019/",
dataset=True, partition_filter=my_second_filter,
boto3_session=sesion, use_threads=True, chunked=True):
chunks+=1
working properly with filters...
this is what I want to get from pyarrow, as it's going to be a lighter library
and not coupled to AWS open source initiatives.
