Redshift

This page will guide you through the setup of Redshift in K using the direct connect method.

Integration details

Step 1) Establish Redshift Access

There are 2 methods for providing K access to Redshift: Super user or Custom user.

Super user method: Create a new Superuser - refer to https://docs.aws.amazon.com/redshift/latest/dg/r_superusers.html to view all required data.

Custom user methods: Create a user with

1. Unrestricted SYSLOG ACCESS - refer to https://docs.aws.amazon.com/redshift/latest/dg/c_visibility-of-data.html. This will allow full access to the STL tables for the user.

   ALTER USER <kada user> SYSLOG ACCESS UNRESTRICTED; -- GRANTS READ ACCESS

    

2. Select Access to existing and future tables in all Schemas for each Database you want K to ingest.

   1. List all existing Schema in the Database by running

      SELECT DISTINCT schema_name FROM svv_all_tables; -- LIST ALL SCHEMAS

       

   2. For each schema above do the following to allow the kada user select access to all tables inside the Schema and any new tables created in the schema thereafter.

      You also must do this for ANY new schemas created in the Database to ensure K has view of it.

       

3. The PG tables are granted per database but generally all users should have access to them on DB creation. In the event the user doesn’t have access, explicit grants will need to be done per new DB in Redshift.

The user used for the extraction must also be able to connect to the the databases needed for extraction.

• Test your connection and click Save

• Select the Databases you wish to load into K and click Finish Setup

  • All databases will be listed. If you have a lot of databases this may take a few seconds to load

• Return to the Sources page and locate the new Redshift source that you loaded

• Click on the clock icon to select Edit Schedule and set your preferred schedule for the Snowflake load

Step 3) Manually run an ad hoc load to test Redshift setup

• Next to your new Source, click on the Run manual load icon
