Example

declare const vpc: ec2.Vpc;

const serverlessCache = new elasticache.ServerlessCache(this, 'ServerlessCache', {
  engine: elasticache.CacheEngine.VALKEY_LATEST,
  backup: {
    // set a backup name before deleting a cache
    backupNameBeforeDeletion: "my-final-backup-name",
  },
  vpc,
});

Properties

Name	Type	Description
engineType🔹	string	The engine type, for example 'valkey', 'redis', or 'memcached'.
majorEngineVersion?🔹	string	The major engine version, for example '9' or '1.6'. Maps directly to the MajorEngineVersion property of AWS::ElastiCache::ServerlessCache. When undefined, the service selects the latest major version automatically.

Methods

Name	Description
toString()🔹	Returns a string representation of this cache engine, for logging and error messages.
static of(engineType, majorEngineVersion?)🔹	Create a new CacheEngine with an arbitrary engine type and major version.

---

toString()🔹

public toString(): string

Returns

• string

Returns a string representation of this cache engine, for logging and error messages.

The format is engineType_majorEngineVersion when a major version is set, or just engineType otherwise (for example, 'valkey_8', 'memcached_1.6', 'redis').

---

static of(engineType, majorEngineVersion?)🔹

public static of(engineType: string, majorEngineVersion?: string): CacheEngine

Parameters

• engineType string — the engine type (for example, 'valkey', 'redis', or 'memcached').
• majorEngineVersion string — the major engine version (for example, '9').

Returns

• CacheEngine

Create a new CacheEngine with an arbitrary engine type and major version.

Use this for engine/version combinations that are not yet represented by a named static member.
