OAT V4.3.0

Release purpose

To better assist users in the operation and maintenance of OceanBase products, this release of OAT V4.3.0 introduces a new deep inspection feature. This feature allows for comprehensive inspections of products, components, and tools managed by OAT, with the ability to view and download detailed inspection reports. Additionally, OCP rolling upgrade functionality has been added, enabling read-only services during the upgrade process. Support for upgrading MetaDB V4.x is also included. Version rollback capabilities for OCP, ODC, and OB Sharding have been enhanced, allowing users to revert to the previous version if an upgrade task fails or issues are discovered during product validation. The odpconsole now supports adding, removing, replacing nodes, and modifying node resource specifications, enabling more flexible business scenarios and customized requirements.
