# IServerlessCache

Represents a Serverless ElastiCache cache.

Extends: IServerlessCache
Extends: IResource, IConnectable, IServerlessCacheRef
Implemented by: ServerlessCache, ServerlessCacheBase

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/serverless-cache-base.ts`](https://github.com/aws/aws-cdk/blob/v2.274.0-alpha.0/packages/@aws-cdk/aws-elasticache-alpha/lib/serverless-cache-base.ts#L110)

## Properties

- `backupArnsToRestore`: string[] — The ARNs of backups restored in the cache.

- `connections`: [Connections](/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.Connections.html) (required) — The network connections associated with this resource.

- `engine`: [CacheEngine](/cdk/api/v2/docs/@aws-cdk_aws-elasticache-alpha.CacheEngine.html) — The cache engine used by this cache.

- `env`: [ResourceEnvironment](/cdk/api/v2/docs/aws-cdk-lib.interfaces.ResourceEnvironment.html) (required) — The environment this resource belongs to.

  For resources that are created and managed in a Stack (those created by
  creating new class instances like `new Role()`, `new Bucket()`, etc.), this
  is always the same as the environment of the stack they belong to.

  For referenced resources (those obtained from referencing methods like
  `Role.fromRoleArn()`, `Bucket.fromBucketName()`, etc.), they might be
  different than the stack they were imported into.

- `kmsKey`: [IKey](/cdk/api/v2/docs/aws-cdk-lib.aws_kms.IKey.html) — The KMS key used for encryption.

- `node`: [Node](/cdk/api/v2/docs/constructs.Node.html) (required) — The tree node.

- `securityGroups`: [ISecurityGroup](/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.ISecurityGroup.html)[] — The security groups associated with this cache.

- `serverlessCacheArn`: string (required) — The ARN of the serverless cache.

- `serverlessCacheName`: string (required) — The name of the serverless cache.

- `serverlessCacheRef`: [ServerlessCacheReference](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_elasticache.ServerlessCacheReference.html) (required) — A reference to a ServerlessCache resource.

- `stack`: [Stack](/cdk/api/v2/docs/aws-cdk-lib.Stack.html) (required) — The stack in which this resource is defined.

- `subnets`: [ISubnet](/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.ISubnet.html)[] — The subnets this cache is deployed in.

- `userGroup`: [IUserGroup](/cdk/api/v2/docs/@aws-cdk_aws-elasticache-alpha.IUserGroup.html) — The user group associated with this cache.

- `vpc`: [IVpc](/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.IVpc.html) — The VPC this cache is deployed in.

## Methods

- `applyRemovalPolicy(policy: RemovalPolicy): void` — Apply the given removal policy to this resource.

  The Removal Policy controls what happens to this resource when it stops
  being managed by CloudFormation, either because you've removed it from the
  CDK application or because you've made a change that requires the resource
  to be replaced.

  The resource can be deleted (`RemovalPolicy.DESTROY`), or left in your AWS
  account for data recovery and cleanup later (`RemovalPolicy.RETAIN`).

- `grant(grantee: IGrantable, ...actions: string[]): Grant` — Grant the given identity custom permissions.

- `grantConnect(grantee: IGrantable): Grant` — Grant connect permissions to the cache.

- `metric(metricName: string, props?: MetricOptions): Metric` — Return the given named metric for this cache.

- `metricActiveConnections(props?: MetricOptions): Metric` — Metric for active connections.

- `metricCacheHitCount(props?: MetricOptions): Metric` — Metric for cache hit count.

- `metricCacheHitRate(props?: MetricOptions): Metric` — Metric for cache hit rate.

- `metricCacheMissCount(props?: MetricOptions): Metric` — Metric for cache miss count.

- `metricDataStored(props?: MetricOptions): Metric` — Metric for data stored in the cache.

- `metricNetworkBytesIn(props?: MetricOptions): Metric` — Metric for network bytes in.

- `metricNetworkBytesOut(props?: MetricOptions): Metric` — Metric for network bytes out.

- `metricProcessingUnitsConsumed(props?: MetricOptions): Metric` — Metric for ECPUs consumed.

- `metricReadRequestLatency(props?: MetricOptions): Metric` — Metric for read request latency.

- `metricWriteRequestLatency(props?: MetricOptions): Metric` — Metric for write request latency.

- `with(...mixins: IMixin[]): IConstruct` — Applies one or more mixins to this construct.

  Mixins are applied in order. The list of constructs is captured at the
  start of the call, so constructs added by a mixin will not be visited.

  **Parameters**

  - `mixins` — The mixins to apply.

  **Returns:** This construct for chaining
