Ahana-managed S3 buckets

When creating an Ahana-managed Presto cluster, Ahana provisions one or more AWS S3 buckets in your Ahana Compute Plane to persist operations data.

Ahana-managed S3 Bucket View

The Ahana-managed S3 Buckets table displays:

  • The S3 Bucket Name.
  • The Presto Cluster that the S3 bucket is attached to.
  • The Bucket Type describes the type of data stored in the S3 bucket.
    • A Query Log S3 bucket stores the query log collected from the Presto cluster.
    • A Cluster Data S3 bucket persists the data generated when running queries via the Ahana Hive Metastore catalog. A Cluster Data S3 bucket is created for a Presto cluster only if an Ahana Hive Metastore is provisioned for the Presto cluster. See Set the Data Lake Settings.
  • Creation Date of the S3 bucket.
  • Status is either Attached or Detached.
    • An Attached S3 bucket is attached to an Ahana-managed Presto cluster in the Ahana Compute Plane. An Attached S3 bucket cannot be deleted.
    • An S3 bucket is Detached when its Presto cluster is deleted without deleting that Presto cluster's S3 buckets. See Delete a Presto Cluster. An S3 bucket must be Detached to be deleted.
  1. To view the content of an S3 bucket, select View for that bucket. The AWS Console for the S3 bucket opens in a new browser window.
