+ Credential configurations for AWS S3, GCP GCS, and Azure ADLS are
supported. The following outlines
+ the currently supported configuration options:
+
+ ## S3 Configurations
+
+ The following configurations should be respected when working with
tables stored in AWS S3
+ - `s3.access-key-id`: id for credentials that provide access to
the data in S3
+ - `s3.secret-access-key`: secret for credentials that provide
access to data in S3
+ - `s3.session-token`: if present, this value should be used for
as the session token
+ - `s3.session-token-expires-at-ms`: the time the aws session
token expires, in milliseconds
+ Extra properties:
+ - `client.region`: region to configure client for making
requests to AWS
Review Comment:
To clarify my point above: I think it's a good thing to distinguish two
levels of config (table-wide vs prefix-specific), like Iceberg does, in spite
of the fact that the two config levels have boundaries that are not always 100%
clear.
