Added v0.5
The S3 connector supports writing files to & from a bucket as well as uploading/downloading.
read:
- s3:
bucket: bucket
key: key
access_key: access_key
secret_access_key: secret_access_key
from wrangles.connectors import s3
df = s3.read(
bucket='bucket',
key='key',
access_key='access_key',
secret_access_key='secret_access_key'
)
The S3 connector also supports the same optional parameters as the file connector. See the file connector for more details.
