Issue #, if available:
#717
Description of changes:
The UNLOAD Redshift operation takes "name-prefix" as a parameter, prepending the output S3 objects with a prefix.
This behavior can be enabled for the
unload_to_files
Wrangler method, but not theunload
call. This is becauseunload
makes a subsequent calls to read parquet files from S3 and expects a specific prefix to read from.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
