This article is specific to the following platforms - Redshift.

Text Output Component

This component creates text files on a specified Amazon S3 bucket, and loads them with data from an Amazon Redshift table or view.

The data can be output to multiple files based on a "per file row count".

Note:This component is similar in effect to the 'S3 Unload' component. Since Text Output pulls the data through the Matillion ETL instance, this component offers some added functionality (such as adding column headers to each file). However, S3 Unload unloads data in parallel directly from Redshift to S3 and so tends to be faster.
