DatabaseClusterBase

class aws_cdk.aws_rds.DatabaseClusterBase(scope, id, *, account=None, environment_from_arn=None, physical_name=None, region=None)

Bases: Resource

A new or imported clustered database.

Parameters:
  • scope (Construct) –

  • id (str) –

  • account (Optional[str]) – The AWS account ID this resource belongs to. Default: - the resource is in the same account as the stack it belongs to

  • environment_from_arn (Optional[str]) – ARN to deduce region and account from. The ARN is parsed and the account and region are taken from the ARN. This should be used for imported resources. Cannot be supplied together with either account or region. Default: - take environment from account, region parameters, or use Stack environment.

  • physical_name (Optional[str]) – The value passed in by users to the physical name prop of the resource. - undefined implies that a physical name will be allocated by CloudFormation during deployment. - a concrete value implies a specific physical name - PhysicalName.GENERATE_IF_NEEDED is a marker that indicates that a physical will only be generated by the CDK if it is needed for cross-environment references. Otherwise, it will be allocated by CloudFormation. Default: - The physical name will be allocated by CloudFormation at deployment time

  • region (Optional[str]) – The AWS region this resource belongs to. Default: - the resource is in the same region as the stack it belongs to

Methods

add_proxy(id, *, secrets, vpc, borrow_timeout=None, client_password_auth_type=None, db_proxy_name=None, debug_logging=None, iam_auth=None, idle_client_timeout=None, init_query=None, max_connections_percent=None, max_idle_connections_percent=None, require_tls=None, role=None, security_groups=None, session_pinning_filters=None, vpc_subnets=None)

Add a new db proxy to this cluster.

Parameters:
  • id (str) –

  • secrets (Sequence[ISecret]) – The secret that the proxy uses to authenticate to the RDS DB instance or Aurora DB cluster. These secrets are stored within Amazon Secrets Manager. One or more secrets are required.

  • vpc (IVpc) – The VPC to associate with the new proxy.

  • borrow_timeout (Optional[Duration]) – The duration for a proxy to wait for a connection to become available in the connection pool. Only applies when the proxy has opened its maximum number of connections and all connections are busy with client sessions. Value must be between 1 second and 1 hour, or Duration.seconds(0) to represent unlimited. Default: cdk.Duration.seconds(120)

  • client_password_auth_type (Optional[ClientPasswordAuthType]) – Specifies the details of authentication used by a proxy to log in as a specific database user. Default: - CloudFormation defaults will apply given the specified database engine.

  • db_proxy_name (Optional[str]) – The identifier for the proxy. This name must be unique for all proxies owned by your AWS account in the specified AWS Region. An identifier must begin with a letter and must contain only ASCII letters, digits, and hyphens; it can’t end with a hyphen or contain two consecutive hyphens. Default: - Generated by CloudFormation (recommended)

  • debug_logging (Optional[bool]) – Whether the proxy includes detailed information about SQL statements in its logs. This information helps you to debug issues involving SQL behavior or the performance and scalability of the proxy connections. The debug information includes the text of SQL statements that you submit through the proxy. Thus, only enable this setting when needed for debugging, and only when you have security measures in place to safeguard any sensitive information that appears in the logs. Default: false

  • iam_auth (Optional[bool]) – Whether to require or disallow AWS Identity and Access Management (IAM) authentication for connections to the proxy. Default: false

  • idle_client_timeout (Optional[Duration]) – The number of seconds that a connection to the proxy can be inactive before the proxy disconnects it. You can set this value higher or lower than the connection timeout limit for the associated database. Default: cdk.Duration.minutes(30)

  • init_query (Optional[str]) – One or more SQL statements for the proxy to run when opening each new database connection. Typically used with SET statements to make sure that each connection has identical settings such as time zone and character set. For multiple statements, use semicolons as the separator. You can also include multiple variables in a single SET statement, such as SET x=1, y=2. not currently supported for PostgreSQL. Default: - no initialization query

  • max_connections_percent (Union[int, float, None]) – The maximum size of the connection pool for each target in a target group. For Aurora MySQL, it is expressed as a percentage of the max_connections setting for the RDS DB instance or Aurora DB cluster used by the target group. 1-100 Default: 100

  • max_idle_connections_percent (Union[int, float, None]) – Controls how actively the proxy closes idle database connections in the connection pool. A high value enables the proxy to leave a high percentage of idle connections open. A low value causes the proxy to close idle client connections and return the underlying database connections to the connection pool. For Aurora MySQL, it is expressed as a percentage of the max_connections setting for the RDS DB instance or Aurora DB cluster used by the target group. between 0 and MaxConnectionsPercent Default: 50

  • require_tls (Optional[bool]) – A Boolean parameter that specifies whether Transport Layer Security (TLS) encryption is required for connections to the proxy. By enabling this setting, you can enforce encrypted TLS connections to the proxy. Default: true

  • role (Optional[IRole]) – IAM role that the proxy uses to access secrets in AWS Secrets Manager. Default: - A role will automatically be created

  • security_groups (Optional[Sequence[ISecurityGroup]]) – One or more VPC security groups to associate with the new proxy. Default: - No security groups

  • session_pinning_filters (Optional[Sequence[SessionPinningFilter]]) – Each item in the list represents a class of SQL operations that normally cause all later statements in a session using a proxy to be pinned to the same underlying database connection. Including an item in the list exempts that class of SQL operations from the pinning behavior. Default: - no session pinning filters

  • vpc_subnets (Union[SubnetSelection, Dict[str, Any], None]) – The subnets used by the proxy. Default: - the VPC default strategy if not specified.

  • account (Optional[str]) – Account which this metric comes from. Default: - Deployment account.

  • color (Optional[str]) – The hex color code, prefixed with ‘#’ (e.g. ‘#00ff00’), to use when this metric is rendered on a graph. The Color class has a set of standard colors that can be used here. Default: - Automatic color

  • dimensions_map (Optional[Mapping[str, str]]) – Dimensions of the metric. Default: - No dimensions.

  • label (Optional[str]) –

    Label for this metric when added to a Graph in a Dashboard. You can use dynamic labels to show summary information about the entire displayed time series in the legend. For example, if you use:: [max: ${MAX}] MyMetric As the metric label, the maximum value in the visible range will be shown next to the time series name in the graph’s legend. Default: - No label

  • period (Optional[Duration]) – The period over which the specified statistic is applied. Default: Duration.minutes(5)

  • region (Optional[str]) – Region which this metric comes from. Default: - Deployment region.

  • statistic (Optional[str]) – What function to use for aggregating. Use the aws_cloudwatch.Stats helper class to construct valid input strings. Can be one of the following: - “Minimum” | “min” - “Maximum” | “max” - “Average” | “avg” - “Sum” | “sum” - “SampleCount | “n” - “pNN.NN” - “tmNN.NN” | “tm(NN.NN%:NN.NN%)” - “iqm” - “wmNN.NN” | “wm(NN.NN%:NN.NN%)” - “tcNN.NN” | “tc(NN.NN%:NN.NN%)” - “tsNN.NN” | “ts(NN.NN%:NN.NN%)” Default: Average

  • unit (Optional[Unit]) – Unit used to filter the metric stream. Only refer to datums emitted to the metric stream with the given unit and ignore all others. Only useful when datums are being emitted to the same metric stream under different units. The default is to use all matric datums in the stream, regardless of unit, which is recommended in nearly all cases. CloudWatch does not honor this property for graphs. Default: - All metric datums in the given metric stream

Return type:

Metric

metric_total_backup_storage_billed(*, account=None, color=None, dimensions_map=None, label=None, period=None, region=None, statistic=None, unit=None)

The total amount of backup storage in bytes for which you are billed.

Attributes

cluster_arn

The ARN of the cluster.

cluster_endpoint

The endpoint to use for read/write operations.

cluster_identifier

Identifier of the cluster.

cluster_read_endpoint

Endpoint to use for load-balanced read-only operations.

cluster_resource_identifier

cluster-ABCD1234EFGH5678IJKL90MNOP.

This AWS Region-unique identifier is used in things like IAM authentication policies.

Type:

The immutable identifier for the cluster; for example

connections

Access to the network connections.

engine

The engine of this Cluster.

May be not known for imported Clusters if it wasn’t provided explicitly.

env

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

instance_endpoints

Endpoints which address each individual replica.

instance_identifiers

Identifiers of the replicas.

node

The tree node.

secret

Secret in SecretsManager to store the database cluster user credentials.

stack

The stack in which this resource is defined.

Static Methods

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:

x (Any) – Any object.

Return type:

bool

Returns:

true if x is an object created from a class which extends Construct.

classmethod is_owned_resource(construct)

Returns true if the construct was created by CDK, and false otherwise.

Parameters:

construct (IConstruct) –

Return type:

bool

classmethod is_resource(construct)

Check whether the given construct is a Resource.

Parameters:

construct (IConstruct) –

Return type:

bool
