Presto Users Overview

Presto users are centrally defined and can be re-used across Presto clusters. This reusability means that cluster creators do not have to recreate identical users in multiple clusters. External principals, such as a business analyst, can maintain a single identity across multiple Ahana-managed Presto clusters.


Presto users are persisted across Ahana Compute Plane upgrades and recreations.

To see all currently-defined Presto users, select Security, then select Presto Users.
