How Do I Add Shards to a Cluster DCS Redis Instance Without Changing the Memory?

Updated on 2022-09-15 GMT+08:00

After a Proxy Cluster or Redis Cluster instance is created, you can reduce the capacity of each shard and add more shards without changing the total memory.

For example, if an 8 GB instance has 4 shards and each shard is 2 GB, you can reduce the shard size to 1 GB and increase the shard quantity to 8.

NOTE:

A shard size of 1 GB cannot be changed.

Procedure

  1. Log in to the management console, and choose Application > Distributed Cache Service in the service list.
  2. Click in the upper left corner to select a region and a project.
  3. In the navigation pane, choose Cache Manager.
  4. Choose More > Modify Specifications in the row containing the desired DCS instance.
  5. On the displayed Modify Instance Specifications page, specify Shard Size and Instance Specification.

  6. Click Next, confirm the details, and click Submit.

    The modification takes about 5 to 30 minutes to complete. After the modification is successful, the instance status changes to Running.
