Step 1) Establish Greenplum Access

You will need to create a user <kada user> for the K Platform.

Generally all users should have access to the pg_catalog tables on Database creation for Greenplum.

In the event the user doesn’t have access, explicit grants will need to be done per new Database in Greenplum to the <kada user>.

GRANT USAGE ON SCHEMA pg_catalog TO <kada user>; GRANT SELECT ON ALL TABLES IN SCHEMA pg_catalog TO <kada user>;

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

PG Tables

The user must have access to these pg_catalog tables per applicable database in Greenplum

  • pg_class

  • pg_namespace

  • pg_proc

  • pg_database

  • pg_language

  • pg_type

  • pg_collation

  • pg_depend

  • pg_sequence

  • pg_constraint

  • pg_authid

  • pg_auth_members

Databases

  • The user must also be able to connect to all databases that you want onboarded.

    • Name: The name you wish to give your Greenplum Instance in K

    • Host: Add your Greenplum host (found in your Greenplum URL)

      • Omit the https:// from the UR

  • Add the Connection details and click Save & Next when connection is successful

    • Host: Use the same details you previously added in the Host setting

    • Username: Add the Greenplum user name you created in Step 1

    • Password: Add the Greenplum user password you created in Step 1

  • 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 Greenplum source that you loaded

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

Note that scheduling a source can take up to 15 minutes to propagate the change.

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

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

  • Confirm how your want the source to be loaded

  • After the source load is triggered, a pop up bar will appear taking you to the Monitor tab in the Batch Manager page. This is the usual page you visit to view the progress of source loads

     

A manual source load will also require a manual run of

  • DAILY

  • GATHER_METRICS_AND_STATS

To load all metrics and indexes with the manually loaded metadata. These can be found in the Batch Manager page

 

Troubleshooting failed loads

  • If the job failed at the extraction step

    • Check the error. Contact KADA Support if required.

    • Rerun the source job

  • If the job failed at the load step, the landing folder failed directory will contain the file with issues.

    • Find the bad record and fix the file

    • Rerun the source job
