Cloudera Operational Database (COD) 1.15 version provides a new option for the upgrade-database command and supports DataHub/OpDB deployment across multiple availability zones.
The upgrade-database command supports a new option to upgrade only the operating system
COD provides a new option --os-upgrade-only for the upgrade-database command, which you can use to upgrade only the operating system to the latest supported version addressing any CVEs that were patched in the operating system. Running the upgrade-database command with this option does not have an effect on the CDP runtime version running on the given cluster.
COD supports DataHub/OpDB deployment across multiple availability zones (Multi-AZ) to ensure high availability
- COD introduces a technical preview version of Multi-AZ deployment capability and is available by special request through your account team.
- When you enable COD, by default it deploys all the databases across three availability zones identified in the SDX by the provided network subnets. COD CLI beta provides a new --disable-multi-az to limit deployments to a single availability zone.
COD can disable ephemeral storage in CLI
COD provides the ability to disable the ephemeral storage using a new command --disable-ephemeral-storage.
COD provides the ability to list all the HBase snapshots using different filters
COD supports listing all the HBase snapshots created within a database of an environment using these filters, time range, snapshot name, and command ID. For example, you can use the time range filter to obtain the snapshots created within a particular time, the command ID filter to know the status of a snapshot operation.
