LocationS3

Source: src/AWS/DataSync/LocationS3.ts

A DataSync location backed by an Amazon S3 bucket. Locations are the source and destination endpoints referenced by a Task.

S3 locations are immutable apart from their tags: any change to the bucket, subdirectory, storage class, or access role replaces the location. Reconcile is idempotent across state loss — the location is re-discovered by its deterministic s3://… URI.

Creating S3 Locations

Bucket root

import * as AWS from "alchemy/AWS";

const source = yield* AWS.DataSync.LocationS3("Source", {
  s3BucketArn: bucket.bucketArn,
  bucketAccessRoleArn: role.roleArn,
});

Prefix + storage class

const dest = yield* AWS.DataSync.LocationS3("Dest", {
  s3BucketArn: bucket.bucketArn,
  bucketAccessRoleArn: role.roleArn,
  subdirectory: "/archive",
  s3StorageClass: "STANDARD_IA",
});
