Modify Data Sources
Modifying a data source that is attached to an active Presto cluster restarts that Presto cluster. All queries running at restart will fail. The Presto cluster moves to pending state during the restart and is unusable until it returns to active state.
To modify a data source:
- In the Ahana SaaS Console, select Data Sources.
Select View for the data source.
Select Modify Data Source.
Edit the values of the data source as needed. See Data Source Properties.
Select Modify Data Source to update the data source with the new information.
Changes take effect immediately.
