Response Structure

  • (dict) –

    Represents the output of a GetApiCache operation.

    • apiCache (dict) –

      The ApiCache object.

      • ttl (integer) –

        TTL in seconds for cache entries.

        Valid values are 1–3,600 seconds.

      • apiCachingBehavior (string) –

        Caching behavior.

        • FULL_REQUEST_CACHING: All requests are fully cached.

        • PER_RESOLVER_CACHING: Individual resolvers that you specify are cached.

      • transitEncryptionEnabled (boolean) –

        Transit encryption flag when connecting to cache. You cannot update this setting after creation.

      • atRestEncryptionEnabled (boolean) –

        At-rest encryption flag for cache. You cannot update this setting after creation.

      • type (string) –

        The cache instance type. Valid values are

        • SMALL

        • MEDIUM

        • LARGE

        • XLARGE

        • LARGE_2X

        • LARGE_4X

        • LARGE_8X (not available in all regions)

        • LARGE_12X

        Historically, instance types were identified by an EC2-style value. As of July 2020, this is deprecated, and the generic identifiers above should be used.

        The following legacy instance types are available, but their use is discouraged:

        • T2_SMALL: A t2.small instance type.

        • T2_MEDIUM: A t2.medium instance type.

        • R4_LARGE: A r4.large instance type.

        • R4_XLARGE: A r4.xlarge instance type.

        • R4_2XLARGE: A r4.2xlarge instance type.

        • R4_4XLARGE: A r4.4xlarge instance type.

        • R4_8XLARGE: A r4.8xlarge instance type.

      • status (string) –

        The cache instance status.

        • AVAILABLE: The instance is available for use.

        • CREATING: The instance is currently creating.

        • DELETING: The instance is currently deleting.

        • MODIFYING: The instance is currently modifying.

        • FAILED: The instance has failed creation.

      • healthMetricsConfig (string) –

        Controls how cache health metrics will be emitted to CloudWatch. Cache health metrics include:

        • NetworkBandwidthOutAllowanceExceeded: The network packets dropped because the throughput exceeded the aggregated bandwidth limit. This is useful for diagnosing bottlenecks in a cache configuration.

        • EngineCPUUtilization: The CPU utilization (percentage) allocated to the Redis process. This is useful for diagnosing bottlenecks in a cache configuration.

        Metrics will be recorded by API ID. You can set the value to ENABLED or DISABLED.
