    # Describes an API key.
    #
    # Customers invoke AppSync GraphQL API operations with API keys as an
    # identity mechanism. There are two key versions:
    #
    # **da1**: We introduced this version at launch in November 2017. These
    # keys always expire after 7 days. Amazon DynamoDB TTL manages key
    # expiration. These keys ceased to be valid after February 21, 2018, and
    # they should no longer be used.
    #
    # * `ListApiKeys` returns the expiration time in milliseconds.
    #
    # * `CreateApiKey` returns the expiration time in milliseconds.
    #
    # * `UpdateApiKey` is not available for this key version.
    #
    # * `DeleteApiKey` deletes the item from the table.
    #
    # * Expiration is stored in DynamoDB as milliseconds. This results in a
    #   bug where keys are not automatically deleted because DynamoDB
    #   expects the TTL to be stored in seconds. As a one-time action, we
    #   deleted these keys from the table on February 21, 2018.
    #
    # **da2**: We introduced this version in February 2018 when AppSync
    # added support to extend key expiration.
    #
    # * `ListApiKeys` returns the expiration time and deletion time in
    #   seconds.
    #
    # * `CreateApiKey` returns the expiration time and deletion time in
    #   seconds and accepts a user-provided expiration time in seconds.
    #
    # * `UpdateApiKey` returns the expiration time and and deletion time in
    #   seconds and accepts a user-provided expiration time in seconds.
    #   Expired API keys are kept for 60 days after the expiration time. You
    #   can update the key expiration time as long as the key isn't
    #   deleted.
    #
    # * `DeleteApiKey` deletes the item from the table.
    #
    # * Expiration is stored in DynamoDB as seconds. After the expiration
    #   time, using the key to authenticate will fail. However, you can
    #   reinstate the key before deletion.
    #
    # * Deletion is stored in DynamoDB as seconds. The key is deleted after
    #   deletion time.

    # Enables and controls the enhanced metrics feature. Enhanced metrics

    # request and error counts, latency, and cache hits/misses. All enhanced
    # metric data is sent to your CloudWatch account, and you can configure
    # the types of data that will be sent.
    #
    # Enhanced metrics can be configured at the resolver, data source, and
    # operation levels. `EnhancedMetricsConfig` contains three required
    # parameters, each controlling one of these categories:
    #
    # 1.  `resolverLevelMetricsBehavior`: Controls how resolver metrics will
    #     be emitted to CloudWatch. Resolver metrics include:
    #
    #     * GraphQL errors: The number of GraphQL errors that occurred.
    #
    #     * Requests: The number of invocations that occurred during a
    #       request.
    #
    #     * Latency: The time to complete a resolver invocation.
    #
    #     * Cache hits: The number of cache hits during a request.
    #
    #     * Cache misses: The number of cache misses during a request.
    #
    #     These metrics can be emitted to CloudWatch per resolver or for all
    #     resolvers in the request. Metrics will be recorded by API ID and
    #     resolver name. `resolverLevelMetricsBehavior` accepts one of these
    #     values at a time:
    #
    #     * `FULL_REQUEST_RESOLVER_METRICS`: Records and emits metric data
    #       for all resolvers in the request.
    #
    #     * `PER_RESOLVER_METRICS`: Records and emits metric data for
    #       resolvers that have the `metricsConfig` value set to `ENABLED`.
    #
    # 2.  `dataSourceLevelMetricsBehavior`: Controls how data source metrics
    #     will be emitted to CloudWatch. Data source metrics include:
    #
    #     * Requests: The number of invocations that occured during a
    #       request.
    #
    #     * Latency: The time to complete a data source invocation.
    #
    #     * Errors: The number of errors that occurred during a data source
    #       invocation.
    #
    #     These metrics can be emitted to CloudWatch per data source or for
    #     all data sources in the request. Metrics will be recorded by API
    #     ID and data source name. `dataSourceLevelMetricsBehavior` accepts
    #     one of these values at a time:
    #
    #     * `FULL_REQUEST_DATA_SOURCE_METRICS`: Records and emits metric
    #       data for all data sources in the request.
    #
    #     * `PER_DATA_SOURCE_METRICS`: Records and emits metric data for
    #       data sources that have the `metricsConfig` value set to
    #       `ENABLED`.
    #
    # 3.  `operationLevelMetricsConfig`: Controls how operation metrics will
    #     be emitted to CloudWatch. Operation metrics include:
    #
    #     * Requests: The number of times a specified GraphQL operation was
    #       called.
    #
    #     * GraphQL errors: The number of GraphQL errors that occurred
    #       during a specified GraphQL operation.
    #
    #     Metrics will be recorded by API ID and operation name. You can set
    #     the value to `ENABLED` or `DISABLED`.
    #
    # @!attribute [rw] resolver_level_metrics_behavior
    #   Controls how resolver metrics will be emitted to CloudWatch.
    #   Resolver metrics include:
    #
    #   * GraphQL errors: The number of GraphQL errors that occurred.
    #
    #   * Requests: The number of invocations that occurred during a
    #     request.
    #
    #   * Latency: The time to complete a resolver invocation.
    #
    #   * Cache hits: The number of cache hits during a request.
