Resizing Shards for a Cluster

OCI Cache supports changing the number of shards for an existing sharded cluster if you need to scale up or down to meet your requirements.

The number of shards per cluster must be an uneven number from 3 to 99, though the maximum number of shards depends on the number of nodes configured per shard, so that the total number of nodes doesn't exceed the cluster node limit of 100. See Sharded Clusters for more information.
Note

You can only resize one configuration setting at a time, and you need to wait for a resize operation to complete before you can start a new resize operation.
