expectedBucketOwner

The AWS account ID that you expect to be the owner of the Amazon S3 bucket specified by ResultConfiguration$OutputLocation . If set, Athena uses the value for ExpectedBucketOwner when it makes Amazon S3 calls to your specified output location. If the ExpectedBucketOwner AWS account ID does not match the actual owner of the Amazon S3 bucket, the call fails with a permissions error. If workgroup settings override client-side settings, then the query uses the ExpectedBucketOwner setting that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
