Class S3TableConfigClient

io.trino.plugin.kinesis.s3config.S3TableConfigClient

All Implemented Interfaces:

Runnable

public class S3TableConfigClient
extends Object
implements Runnable

Utility class to retrieve table definitions from a common place on Amazon S3.

This is so that we can add new tables in a central "metastore" location without having to update every single node with the files.

This makes calls to Amazon AWS using the S3 client.
