You can specify one or more partition columns so that unloaded data is automatically partitioned into folders in your Amazon S3 bucket. For example, you can choose to unload your marketing data and partition it by year, month, and day columns. This enables your queries to take advantage of partition pruning and skip scanning non-relevant partitions, improving query performance and minimizing cost.
For more information, refer to the Amazon Redshiftdocumentation.
Amazon Redshift data lake export is supported with Redshift release version 1.0.10480 or later. Refer to theAWS Region Table for Amazon Redshift availability.
