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

Impala Virtual Warehouse EBS volume type provisioning (Preview)

Impala Virtual Warehouse when configured to spill to EBS volumes can now also spill to the Amazon gp3 Elastic Block Store volumes in addition to gp2 and st1 volumes. CDP automatically provisions the gp3 volume type when conditions exist to reduce cost. The gp3 volume has slightly reduced baseline cost compared to gp2 and other advantages. Provisioning might occur when you specify scratch space limits for spilling Impala queries. Also, when you create an Impala Virtual Warehouse on new CDW environment, CDP uses a gp3 volume. For more information, see Amazon documentation.
