Updating a kdb cluster database

You can update the databases mounted on a kdb cluster using the console. This feature is only available for HDB clusters types. With this feature, you can update the data in a cluster by selecting a changeset. You can also update the cache by providing database paths. You can't change a database name or add a new database if you created a cluster without one.

You can also choose how you want to update the databases on the cluster by selecting a deployment mode.

To update a kdb cluster database

1. Sign in to the AWS Management Console and open the Amazon FinSpace console at https://console.aws.amazon.com/finspace.

2. Choose Kdb environments.

3. From the list of environments, choose a kdb environment.

4. On the environment details page, choose the Clusters tab.

5. From the list of clusters, choose the one where you want to update the database. The cluster details page opens.

6. On the cluster details page, choose the Details tab.

7. Under Data management and storage section, choose Edit.

   Note

   This button is not available for RDB and Gateway type clusters.

8. On the edit page, modify the changeset that you want to cache as needed.

9. Choose a deployment mode from one of the following options.

   • Rolling – (Default) To update the database, this option stops the existing q process and starts a new q process with the updated database configuration. The initialization script re-runs when the new q process starts.

   • No restart – This option updates the database but doesn't stop the existing q process. No restart is often quicker than the other deployment modes because it reduces the turnaround time to update the changeset configuration for a kdb database on your cluster. This option doesn't re-run the initialization script.

   Note

   After the update completes, you must re-load the updated database. However, if you use a historical database (HDB) cluster with a single database in a rolling deployment, FinSpace autoloads the database after an update.

10. Choose Save changes. The cluster details page opens and the updated information is displayed once the cluster updates successfully.
