# ElastiCache operations 22 of 24 listed operations are implemented. Back to [ElastiCache](/docs/services/elasticache/index.md). ## Summary | Category | ✅ Supported | ❌ Unsupported | | --- | --- | --- | | General | 22 | 2 | --- ## Endpoints ### General | Operation | Status | Notes | AWS Docs | | --- | --- | --- | --- | | `AddTagsToResource` | ✅ Supported | ARN-scoped tag storage | [docs](https://docs.aws.amazon.com/AmazonElastiCache/latest/APIReference/API_AddTagsToResource.html) | | `CreateCacheCluster` | ✅ Supported | Docker-backed (redis/valkey/memcached); async creating→available once the engine answers PING; a cache that never answers ends in `incompatible-network`; port auto-alloc; PreferredAvailabilityZone, CacheParameterGroupName and inline Tags round-trip; the CloudFormation resource's Port, VpcSecurityGroupIds, AZMode, TransitEncryptionEnabled, SnapshotRetentionLimit, NotificationTopicArn, PreferredMaintenanceWindow, AutoMinorVersionUpgrade and LogDeliveryConfigurations are not modeled | [docs](https://docs.aws.amazon.com/AmazonElastiCache/latest/APIReference/API_CreateCacheCluster.html) | | `CreateCacheParameterGroup` | ✅ Supported | Stores name, family, description, and ARN | [docs](https://docs.aws.amazon.com/AmazonElastiCache/latest/APIReference/API_CreateCacheParameterGroup.html) | | `CreateCacheSubnetGroup` | ✅ Supported | Stores name, description, and subnet IDs | [docs](https://docs.aws.amazon.com/AmazonElastiCache/latest/APIReference/API_CreateCacheSubnetGroup.html) | | `CreateReplicationGroup` | ✅ Supported | Docker-backed (single primary node); async creating→available once the primary answers PING; a group that never answers ends in `create-failed`; `CacheSubnetGroupName` places the group in that subnet group’s VPC; Engine/EngineVersion pick the container image (redis/valkey/memcached) — previously dropped on Create, defaulting every group to redis regardless of the template (#543); SnapshotRetentionLimit and PrimaryClusterId also round-trip from Create; the CloudFormation resource’s NumCacheClusters, NumNodeGroups, ReplicasPerNodeGroup, CacheParameterGroupName, AtRestEncryptionEnabled, TransitEncryptionEnabled, AuthToken, KmsKeyId, UserGroupIds, CacheSecurityGroupNames, LogDeliveryConfigurations, Tags, NotificationTopicArn, PreferredMaintenanceWindow, SnapshotWindow and SecurityGroupIds are not modeled | [docs](https://docs.aws.amazon.com/AmazonElastiCache/latest/APIReference/API_CreateReplicationGroup.html) | | `CreateServerlessCache` | ✅ Supported | Docker-backed (redis/valkey/memcached); async creating→available once the engine answers PING; a cache that never answers ends in `create-failed`; CloudFormation ServerlessCache supported | [docs](https://docs.aws.amazon.com/AmazonElastiCache/latest/APIReference/API_CreateServerlessCache.html) | | `DeleteCacheCluster` | ✅ Supported | Sets status to "deleting";
