use AWS_PROFILE in pandas.read_parquet

Question

I'm testing this locally where I have a ~/.aws/config file.

~/.aws/config looks some thing like:

[profile a] 
...
[profile b]
...

I also have a AWS_PROFILE environmental variable set as "a".

I would like to read a file in which is accessible with profile b using pandas.

I am able to access it through s3fs by doing:

import s3fs
fs = s3fs.S3FileSystem(profile="b")
fs.get("BUCKET/FILE.parquet", "FILE.parquet")
pd.read_parquet("FILE.parquet")

However, if I try to pass this to pd.read_parquet using storage_options I get a PermissionError: Forbidden.

pd.read_parquet(
    "s3://BUCKET/FILE.parquet",
    storage_options={"profile": "b"},
)

Note: there is an old question somewhat related to this but it didn't help: How to read parquet file from s3 using dask with specific AWS profile

Answer 1

You just need to add the following argument to the function:

storage_options=dict(profile='your_profile_name')

Hence the read statement is:

pd.read_parquet("s3://your_bucket",storage_options=dict(profile='your_profile_name'))
