You can change the capacity of an instance. Through this operation, the specifications of the instance can be adjusted to meet different capacity requirements.
Before You Begin
This operation can only be performed when the DCS Redis instance is in the Running state.
Impacts
l During instance expansion, the instance will be intermittently disconnected for 30 seconds once or twice.
l To ensure that the newly expanded instance can quickly catch up with the incremental data of the original instance and avoid dual-writing of data caused by DNS caching, each shard node of the instance will be in a read-only state for 1 minute during the expansion.
l After the expansion, the instance ID, connection address, data, trustlist configuration, and configuration of the created account and password will remain the same as before.
Procedure
1. Log in to the Redis management console.
2. Select the region of the instance in the upper left corner of the management console.
3. On the instance list page, select the row of the instance and click the More > Expand button to enter the instance expansion page.
