When you need more computing and storage resources to meet service needs, add more nodes to the cluster on the management console.
During the redistribution, do not perform queries that take more than 20 minutes (The default time for applying for the write lock during redistribution is 20 minutes). Otherwise, data redistribution may fail due to timeout when waiting for locking.
All clusters are displayed by default.
The scale-out page is displayed.
If the node quota is insufficient, click Increase quota to submit a work order and apply for higher node quota.
If the number of applied nodes, vCPU (cores), or memory (GB) exceed the user's remaining quota, a warning dialog box is displayed indicating insufficient quota and displaying the detailed remaining quota and the current quota application information. In this case, you can click Increase quota in the warning dialog box to submit a work order and apply for higher node quota.
For details about quota, see What Is User Quota?.
