Amazon Redshift data output

This article provides an introduction to Amazon Redshift along with a guide on creating an Amazon Redshift data output using Upsolver.

What is Amazon Redshift?

Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud.

An Amazon Redshift data warehouse is a collection of computing resources called nodes, which are organized into a group called a cluster. Each cluster runs an Amazon Redshift engine and contains one or more databases.

Create an output to Amazon Redshift

1. Go to the Outputs page and click New.

2. Select Amazon Redshift as your output type.

3. Name your output and select your Data Sources.

4. Select New to create a new table or Existing to output to an existing table. Then click Next.

If outputting to an existing table, complete the database options as prompted before clicking Next again. If necessary, create a new Redshift connection.

Click Properties to review this output's properties. See: Output properties

How many of the events in this data source include this field, expressed as a percentage (e.g. 20.81%).

The percentage distribution of the field values. These distribution values can be exported by clicking Export.

The number of fields in the selected hierarchy.

  • If required, modify the column name under Schema Column.

Alternatively, add columns by clicking Add New Column.

  • Provide a Column Name as well as select a Column Type.

    • If desired, give the column a Default Value then click Save.

  • This column will now be added under the Data Source Field in the Schema tab.

Toggle from UI to SQL at any point to view the corresponding SQL code for your selected output.

You can also edit your output directly in SQL. See: Transform with SQL

8. Add any required calculated fields and review them in the Calculated Fields tab. See: Adding calculated fields

9. Add any required lookups and review them under the Calculated Fields tab.

10. Through the Filters tab, add a filter like WHERE in SQL to the data source. See: Adding filters

11. Click Make Aggregated to turn the output into an aggregated output. Read the warning before clicking OK and then add the required aggregation. This aggregation field will then be added to the Schema tab. See: Aggregation functions

12. In the Aggregation Calculated Fields area under the Calculated Fields tab, add any required calculated fields on aggregations. See: Functions, Aggregation functions

13. To keep only the latest event per upsert key, click More > Manage Upserts then select the following:

  • Keys: A unique key identifying a row in the table

  • Deletions: The delete key (events with the value true in their deletion key field will be deleted)

See: Data types and features, How do upserts work?

Click Preview at any time to view a preview of your current output.

14. Click Run and fill out the following fields:

See: Running an output, Database output options

15. Click Next and complete the following:

Select the compute cluster to run the calculation on. Alternatively, click the drop-down and create a new compute cluster.

16. Finally, click Deploy to run the output. It will show as Running in the output panel and is now live in production and consumes compute resources.

You have now successfully outputted your table to Redshift.
