This topic describes the features of OceanBase Admin Toolkit (OAT) V4.3.1.
New features
Resource change features:
- You can change the resources of the component OBDNS.
- You can change the resources of the tool OBLB.
Optimized features
Optimization of Product/Component Resource Change Logic:
Resource change tasks only copy and load images on servers with newly added nodes.
In scenarios where only container resource specifications change, the implementation method shifts from rebuilding the container to using Docker Update and Docker Restart.
Optimization of Server Initialization:
- Add the
min_cpuandmin_memoryfields to specify specifications (CPU and memory) in the initialization server request, and check the server according to the user-specified specifications.Note
Currently, the console does not support setting the
min_cpuandmin_memoryfields. You can use this feature by calling the API.
- Add the
