Halaman ini menjelaskan cara menskalakan instance Memorystore for Redis Cluster.
Kapasitas instance Anda ditentukan oleh jumlah shard dalam instance Anda dan jenis node instance Anda.
Untuk menskalakan instance, Anda harus mengubah jumlah shard atau jenis node.
Untuk mengetahui informasi selengkapnya tentang perilaku instance selama penskalaan, lihat
Tentang penskalaan kapasitas instance.
Menskalakan jumlah shard
Anda dapat menambah atau mengurangi jumlah shard untuk instance menggunakan
Google Cloud konsol atau Google Cloud CLI.
Konsol
Di konsol Google Cloud , buka halaman Memorystore for Redis Cluster.
SHARD_COUNT: jumlah shard dalam instance Anda. Jumlah shard menentukan total kapasitas memori untuk menyimpan data instance. Untuk mengetahui informasi selengkapnya tentang spesifikasi cluster dan node untuk instance Memorystore for Redis Cluster, lihat Spesifikasi cluster dan node.
REGION_ID: region tempat instance Anda berada (misalnya, us-central1)
Periksa output untuk melihat apakah kondisi berikut ada:
Output berisi bagian redisConfigs.
Parameter maxmemory-clients, maxmemory, atau maxclients muncul di bagian ini.
Jika salah satu parameter ini muncul, saat Anda menskalakan jenis node untuk instance, Anda harus menskalakan nilai untuk parameter guna mencerminkan nilai yang dapat diterima oleh Memorystore for Redis Cluster untuk jenis node yang diskalakan. Untuk informasi
selengkapnya, lihat Parameter konfigurasi yang dapat diubah.
NODE_TYPE: jenis node yang ingin Anda skalakan
instance-nya. Nilai yang dapat diterima untuk parameter ini adalah redis-shared-core-nano, redis-standard-small, redis-highmem-medium, dan redis-highmem-xlarge.
Untuk contoh ini, Anda menskalakan jenis node instance my-instance ke redis-highmem-medium. Instance ini berada di region us-central1.

In the Google Cloud console, go to the **Memorystore for Redis Cluster** page.\n\n [Memorystore for Redis Cluster](https://console.cloud.google.com/memorystore/redis/clusters?)\n2. Click your cluster ID.\n\n3. In the **Configurations** section, click the pencil icon next to\n **Shards**.\n\n4. In the **Shards** field, enter the number of shards to which you want to\n scale your instance.\n\n5. Click **Update cluster**.\n\n### gcloud\n\nTo scale the number of shards for an instance, use the [`gcloud redis clusters update`](/sdk/gcloud/reference/redis/clusters/update) command: \n\n```\ngcloud redis clusters update INSTANCE_ID \\\n--region=REGION_ID \\\n--shard-count=SHARD_COUNT\n```\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e: the ID of your instance.\n- \u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e: the region where your instance is located.\n- \u003cvar translate=\"no\"\u003eSHARD_COUNT\u003c/var\u003e: the number of shards in your instance. The shard count determines the total memory capacity for storing instance data. For more information about cluster and node specifications for Memorystore for Redis Cluster instances, see [Cluster and node specification](/memorystore/docs/cluster/cluster-node-specification).\n\nFor example: \n\n```\ngcloud redis clusters update my-instance \\\n--region=us-central1 \\\n--shard-count=8\n```\n\nScale the node type\n-------------------\n\nYou can scale the node type for an instance by using the [Google Cloud CLI](/sdk/gcloud). \n\n### gcloud\n\n1. To retrieve information about an instance, use the [`gcloud redis clusters describe`](/sdk/gcloud/reference/redis/clusters/describe) command:\n\n ```\n gcloud redis clusters describe INSTANCE_ID \\\n --region=REGION_ID\n ```\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e: the ID of your instance\n - \u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e: the region where your instance is located (for example, `us-central1`)\n2. Check the output to see if the following conditions exist:\n\n 1. The output contains a `redisConfigs` section.\n\n 2. The `maxmemory-clients`, `maxmemory`, or `maxclients` parameters appear\n in this section.\n\n If any of these parameters appear, then when you scale the node type for the\n instance, you must scale the values for the parameters to reflect values\n that Memorystore for Redis Cluster can accept for the scaled node type. For more\n information, see [Modifiable configuration parameters](/memorystore/docs/cluster/supported-instance-configurations#modifiable_configuration_parameters).\n3. To scale the node type, use the [`gcloud redis clusters update`](/sdk/gcloud/reference/redis/clusters/update) command:\n\n ```\n gcloud redis clusters update INSTANCE_ID \\\n --region=REGION_ID \\\n --node-type=NODE_TYPE\n ```\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e: the ID of your instance.\n - \u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e: the region where your instance is located.\n - \u003cvar translate=\"no\"\u003eNODE_TYPE\u003c/var\u003e: the node type to which you want to scale your\n instance. Acceptable values for this parameter are `redis-shared-core-nano`, `redis-standard-small`, `redis-highmem-medium`, and `redis-highmem-xlarge`.\n\n | **Note:** You can't scale your instance down to the `redis-shared-core-nano` node type.\n | **Caution** : We recommend that you use the `redis-shared-core-nano` node type for development or testing purposes only. If you run Memorystore for Redis Cluster in a production environment, then we recommend using the `redis-standard-small`, `redis-highmem-medium`, or `redis-highmem-xlarge` node types. For more information about these node types, see [Choose a node type](/memorystore/docs/cluster/cluster-node-specification#choose_a_node_type).\n\n For this example, you scale the node type of the `my-instance` instance to `redis-highmem-medium`. This instance is located in the `us-central1`\n region. \n\n ```\n gcloud redis clusters update my-instance \\\n --region=us-central1 \\\n --node-type=redis-highmem-medium\n ```\n\n For this example, you change the value of the `maxclients` parameter to\n `15,000`. \n\n ```\n gcloud redis clusters update my-instance \\\n --region=us-central1 \\\n --node-type=redis-highmem-medium \\\n --update-redis-config=maxclients=15000\n ```\n\n\u003cbr /\u003e"]]
