If you’re managing Presto on your own, either through your own installation or through a service like AWS EMR or AWS Athena, you have to maintain and manage all of the catalogs and configurations attached to your cluster. That means that if you take your cluster down, you’ll lose those catalogs and configurations – they are not maintained for your cluster.
You can use the Ahana Cloud managed service for Presto to help with this. Ahana Cloud manages all of that for you, so you don’t have to worry about losing catalogs and configurations attached to your Presto cluster. You also get Presto bundled with data sources like the Hive metastore, Apache Superset, and more.
