Resizing Shards for an OCI Cache Cluster

Change the shard size for an OCI Cache 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 OCI Cache 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.
    1. On the Clusters list page, find the cluster that you want to work with. If you need help finding the list page or the cluster, see Listing OCI Cache Clusters.
    2. From the Actions menu for the cluster, select Resize shards.
    3. In the Resize shards panel, enter an odd number between 3 and 99 for Number of shards.
    4. Select Resize.

  • Use the oci redis redis-cluster redis-cluster update command and required parameters to resize the shards for a cluster:

    oci redis redis-cluster redis-cluster update --redis-cluster-id <cluster_OCID> --shard-count <shard_count> [OPTIONS]
    For information about using the CLI, see Command Line Interface (CLI). For a complete list of flags and options available for CLI commands, see the CLI Command Reference.

  • Run the UpdateRedisCluster operation to resize the shards for a cluster.
