This release of the Cloudera Data Warehouse (CDW) service on CDP Public Cloud introduces these changes.

S3 buckets created by CDW on AWS environments are now encrypted by default with SSE🔗

When you use the latest cross-account role from Management Console to register an environment, S3 buckets created by CDW during AWS environment activation, are now encrypted by default with SSE-S3. This provides server-side object encryption (SSE), which protects data at rest. Before this enhancement, S3 buckets were created with only object-level encryption for every object in the bucket during environment activation.

Impala Virtual Warehouses can now be recovered after going into an error state🔗

Impala resources are not deleted when the Virtual Warehouse goes into an error state. Consequently, if an Impala Virtual Warehouse goes into an error state, you can now use the Edit option to recover the Virtual Warehouse with its original configurations.

Impala Virtual Warehouses now use node memory more efficiently🔗

Impala coordinators now can use ~13GiB more of available memory on a node to better support concurrent query execution.
