- `connectionType`: string — The connection type for the serverless cache.

  Valid values are vpc or public.

- `dailySnapshotTime`: string — The daily time that a cache snapshot will be created.

- `description`: string — A description of the serverless cache.

- `endpoint`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnServerlessCache.EndpointProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_elasticache.CfnServerlessCache.EndpointProperty.html) — Represents the information required for client programs to connect to a cache node.

  This value is read-only.

- `engine`: string (required) — The engine the serverless cache is compatible with.

- `finalSnapshotName`: string — The name of the final snapshot taken of a cache before the cache is deleted.

- `majorEngineVersion`: string — The version number of the engine the serverless cache is compatible with.

- `networkType`: string — The network type for the serverless cache.

  Valid values are ipv4, ipv6, or dual_stack.

- `readerEndpoint`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnServerlessCache.EndpointProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_elasticache.CfnServerlessCache.EndpointProperty.html) — Represents the information required for client programs to connect to a cache node.

  This value is read-only.

- `securityGroupIds`: string | [ISecurityGroupRef](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_ec2.ISecurityGroupRef.html)[] — The IDs of the EC2 security groups associated with the serverless cache.
