java.lang.Object

org.apache.iceberg.aws.s3.S3FileIO

All Implemented Interfaces:

java.io.Closeable, java.io.Serializable, java.lang.AutoCloseable, org.apache.iceberg.io.FileIO

public class S3FileIO
extends java.lang.Object
implements org.apache.iceberg.io.FileIO

FileIO implementation backed by S3.

Locations used must follow the conventions for S3 URIs (e.g. s3://bucket/path...). URIs with schemes s3a, s3n, https are also treated as s3 file paths. Using this FileIO with other schemes will result in ValidationException.
