Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :db_instance_identifier (required, String) —

    The DB instance identifier of the Read Replica. This identifier is the unique key that identifies a DB instance. This parameter is stored as a lowercase string.

  • :db_instance_class (String) —

    The compute and memory capacity of the Read Replica, for example, ‘db.m4.large`. Not all DB instance classes are available in all AWS Regions, or for all database engines. For the full list of DB instance classes, and availability for your engine, see [DB Instance Class] in the *Amazon RDS User Guide.*

    Default: Inherits from the source DB instance.

    [1]: docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.DBInstanceClass.html

  • :availability_zone (String) —

    The Amazon EC2 Availability Zone that the Read Replica is created in.

    Default: A random, system-chosen Availability Zone in the endpoint’s AWS Region.

    The port number that the DB instance uses for connections.

    Default: Inherits from the source DB instance

    Valid Values: ‘1150-65535`

  • :multi_az (Boolean) —

    Specifies whether the Read Replica is in a Multi-AZ deployment.

    You can create a Read Replica as a Multi-AZ DB instance. RDS creates a standby of your replica in another Availability Zone for failover support for the replica. Creating your Read Replica as a Multi-AZ DB instance is independent of whether the source database is a Multi-AZ DB instance.

  • :auto_minor_version_upgrade (Boolean) —

    Indicates that minor engine upgrades are applied automatically to the Read Replica during the maintenance window.

    Default: Inherits from the source DB instance

  • :iops (Integer) —

    The amount of Provisioned IOPS (input/output operations per second) to be initially allocated for the DB instance.

  • :option_group_name (String) —

    The option group the DB instance is associated with. If omitted, the default option group for the engine specified is used.

  • :publicly_accessible (Boolean) —

    Specifies the accessibility options for the DB instance. A value of true specifies an Internet-facing instance with a publicly resolvable DNS name, which resolves to a public IP address. A value of false specifies an internal instance with a DNS name that resolves to a private IP address. For more information, see CreateDBInstance.

  • :tags (Array<Types::Tag>) —

    A list of tags. For more information, see [Tagging Amazon RDS Resources].

    [1]: docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Tagging.html

  • :db_subnet_group_name (String) —

    Specifies a DB subnet group for the DB instance. The new DB instance is created in the VPC associated with the DB subnet group. If no DB subnet group is specified, then the new DB instance is not created in a VPC.

    Constraints:

    • Can only be specified if the source DB instance identifier specifies a DB instance in another AWS Region.

    • If supplied, must match the name of an existing DBSubnetGroup.

    • The specified DB subnet group must be in the same AWS Region in which the operation is running.

    • All Read Replicas in one AWS Region that are created from the same source DB instance must either:&gt;

      • Specify DB subnet groups from the same VPC. All these Read Replicas are created in the same VPC.

      • Not specify a DB subnet group. All these Read Replicas are created outside of any VPC.

    Example: ‘mySubnetgroup`

  • :storage_type (String) —

    Specifies the storage type to be associated with the Read Replica.

    Valid values: ‘standard | gp2 | io1`

    If you specify ‘io1`, you must also include a value for the `Iops` parameter.

    Default: ‘io1` if the `Iops` parameter is specified, otherwise `standard`

  • :copy_tags_to_snapshot (Boolean) —

    True to copy all tags from the Read Replica to snapshots of the Read Replica, and otherwise false. The default is false.

  • :monitoring_interval (Integer) —

    The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the Read Replica. To disable collecting Enhanced Monitoring metrics, specify 0. The default is 0.

    If ‘MonitoringRoleArn` is specified, then you must also set `MonitoringInterval` to a value other than 0.

    Valid Values: ‘0, 1, 5, 10, 15, 30, 60`

  • :monitoring_role_arn (String) —

    The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to Amazon CloudWatch Logs. For example, ‘arn:aws:iam:123456789012:role/emaccess`. For information on creating a monitoring role, go to [To create an IAM role for Amazon RDS Enhanced Monitoring].

    If ‘MonitoringInterval` is set to a value other than 0, then you must supply a `MonitoringRoleArn` value.

    [1]: docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Monitoring.html#USER_Monitoring.OS.IAMRole

  • :kms_key_id (String) —

    The AWS KMS key ID for an encrypted Read Replica. The KMS key ID is the Amazon Resource Name (ARN), KMS key identifier, or the KMS key alias for the KMS encryption key.

    If you specify this parameter when you create a Read Replica from an unencrypted DB instance, the Read Replica is encrypted.

    If you create an encrypted Read Replica in the same AWS Region as the source DB instance, then you do not have to specify a value for this parameter. The Read Replica is encrypted with the same KMS key as the source DB instance.

    If you create an encrypted Read Replica in a different AWS Region, then you must specify a KMS key for the destination AWS Region. KMS encryption keys are specific to the AWS Region that they are created in, and you can’t use encryption keys from one AWS Region in another AWS Region.

  • :pre_signed_url (String) —

    The URL that contains a Signature Version 4 signed request for the ‘CreateDBInstanceReadReplica` API action in the source AWS Region that contains the source DB instance.

    You must specify this parameter when you create an encrypted Read Replica from another AWS Region by using the Amazon RDS API. You can specify the ‘–source-region` option instead of this parameter when you create an encrypted Read Replica from another AWS Region by using the AWS CLI.

    The presigned URL must be a valid request for the ‘CreateDBInstanceReadReplica` API action that can be executed in the source AWS Region that contains the encrypted source DB instance. The presigned URL request must contain the following parameter values:

    • ‘DestinationRegion` - The AWS Region that the encrypted Read Replica is created in. This AWS Region is the same one where the `CreateDBInstanceReadReplica` action is called that contains this presigned URL.

      For example, if you create an encrypted DB instance in the us-west-1 AWS Region, from a source DB instance in the us-east-2 AWS Region, then you call the ‘CreateDBInstanceReadReplica` action in the us-east-1 AWS Region and provide a presigned URL that contains a call to the `CreateDBInstanceReadReplica` action in the us-west-2 AWS Region. For this example, the `DestinationRegion` in the presigned URL must be set to the us-east-1 AWS Region.

    • ‘KmsKeyId` - The AWS KMS key identifier for the key to use to encrypt the Read Replica in the destination AWS Region. This is the same identifier for both the `CreateDBInstanceReadReplica` action that is called in the destination AWS Region, and the action contained in the presigned URL.

    • ‘SourceDBInstanceIdentifier` - The DB instance identifier for the encrypted DB instance to be replicated. This identifier must be in the Amazon Resource Name (ARN) format for the source AWS Region. For example, if you are creating an encrypted Read Replica from a DB instance in the us-west-2 AWS Region, then your `SourceDBInstanceIdentifier` looks like the following example: `arn:aws:rds:us-west-2:123456789012:instance:mysql-instance1-20161115`.

    To learn how to generate a Signature Version 4 signed request, see [Authenticating Requests: Using Query Parameters (AWS Signature Version 4)] and [Signature Version 4 Signing Process].

  • :enable_iam_database_authentication (Boolean) —

    True to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts, and otherwise false.

    You can enable IAM database authentication for the following database engines

    • For MySQL 5.6, minor version 5.6.34 or higher

    • For MySQL 5.7, minor version 5.7.16 or higher

    • Aurora 5.6 or higher.

    Default: ‘false`

  • :enable_performance_insights (Boolean) —

    True to enable Performance Insights for the read replica, and otherwise false.

    For more information, see [Using Amazon Performance Insights] in the *Amazon Relational Database Service User Guide*.

    [1]: docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_PerfInsights.html

  • :performance_insights_kms_key_id (String) —

    The AWS KMS key identifier for encryption of Performance Insights data. The KMS key ID is the Amazon Resource Name (ARN), KMS key identifier, or the KMS key alias for the KMS encryption key.

  • :performance_insights_retention_period (Integer) —

    The amount of time, in days, to retain Performance Insights data. Valid values are 7 or 731 (2 years).

  • :enable_cloudwatch_logs_exports (Array<String>) —

    The list of logs that the new DB instance is to export to CloudWatch Logs. The values in the list depend on the DB engine being used. For more information, see [Publishing Database Logs to Amazon CloudWatch Logs ][1] in the *Amazon Relational Database Service User Guide*.

    [1]: docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_LogAccess.html#USER_LogAccess.Procedural.UploadtoCloudWatch

  • :processor_features (Array<Types::ProcessorFeature>) —

    The number of CPU cores and the number of threads per core for the DB instance class of the DB instance.

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :allocated_storage (Integer) —

    The new amount of storage (in gibibytes) to allocate for the DB instance.

    For MariaDB, MySQL, Oracle, and PostgreSQL, the value supplied must be at least 10% greater than the current value. Values that are not at least 10% greater than the existing value are rounded up so that they are 10% greater than the current value.

    For the valid values for allocated storage for each engine, see CreateDBInstance.

  • :db_instance_class (String) —

    The new compute and memory capacity of the DB instance, for example, ‘db.m4.large`. Not all DB instance classes are available in all AWS Regions, or for all database engines. For the full list of DB instance classes, and availability for your engine, see [DB Instance Class] in the *Amazon RDS User Guide.*

    If you modify the DB instance class, an outage occurs during the change. The change is applied during the next maintenance window, unless ‘ApplyImmediately` is specified as `true` for this request.

    Default: Uses existing setting

    [1]: docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.DBInstanceClass.html

  • :db_subnet_group_name (String) —

    The new DB subnet group for the DB instance. You can use this parameter to move your DB instance to a different VPC. If your DB instance is not in a VPC, you can also use this parameter to move your DB instance into a VPC. For more information, see [Updating the VPC for a DB Instance].

    Changing the subnet group causes an outage during the change. The change is applied during the next maintenance window, unless you specify ‘true` for the `ApplyImmediately` parameter.

    Constraints: If supplied, must match the name of an existing DBSubnetGroup.

    Example: ‘mySubnetGroup`

    [1]: docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_VPC.WorkingWithRDSInstanceinaVPC.html#USER_VPC.Non-VPC2VPC

  • :db_security_groups (Array<String>) —

    A list of DB security groups to authorize on this DB instance. Changing this setting doesn’t result in an outage and the change is asynchronously applied as soon as possible.

    Constraints:

    • If supplied, must match existing DBSecurityGroups.

    ^

  • :vpc_security_group_ids (Array<String>) —

    A list of EC2 VPC security groups to authorize on this DB instance. This change is asynchronously applied as soon as possible.

    **Amazon Aurora**

    Not applicable. The associated list of EC2 VPC security groups is managed by the DB cluster. For more information, see ModifyDBCluster.

    Constraints:

    • If supplied, must match existing VpcSecurityGroupIds.

    ^

  • :apply_immediately (Boolean) —

    Specifies whether the modifications in this request and any pending modifications are asynchronously applied as soon as possible, regardless of the ‘PreferredMaintenanceWindow` setting for the DB instance.

    If this parameter is set to ‘false`, changes to the DB instance are applied during the next maintenance window. Some parameter changes can cause an outage and are applied on the next call to RebootDBInstance, or the next failure reboot. Review the table of parameters in

    Modifying a DB Instance and Using the Apply Immediately Parameter][1

    to see the impact that setting ‘ApplyImmediately` to `true` or `false` has for each modified parameter and to determine when the changes are applied.

    Default: ‘false`

    [1]: docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Overview.DBInstance.Modifying.html

  • :master_user_password (String) —

    The new password for the master user. The password can include any printable ASCII character except “/”, “”“, or ”@“.

    Changing this parameter doesn’t result in an outage and the change is asynchronously applied as soon as possible. Between the time of the request and the completion of the request, the ‘MasterUserPassword` element exists in the `PendingModifiedValues` element of the operation response.

    **Amazon Aurora**

    Not applicable. The password for the master user is managed by the DB cluster. For more information, see ModifyDBCluster.

    Default: Uses existing setting

    MariaDB

    Constraints: Must contain from 8 to 41 characters.

    **Microsoft SQL Server**

    Constraints: Must contain from 8 to 128 characters.

    Constraints: Must contain from 8 to 30 characters.

    PostgreSQL

    Constraints: Must contain from 8 to 128 characters.

    <note markdown=“1”> Amazon RDS API actions never return the password, so this action provides a way to regain access to a primary instance user if the password is lost. This includes restoring privileges that might have been accidentally revoked.

    </note>
  • :db_parameter_group_name (String) —

    The name of the DB parameter group to apply to the DB instance. Changing this setting doesn’t result in an outage. The parameter group name itself is changed immediately, but the actual parameter changes are not applied until you reboot the instance without failover. The db instance will NOT be rebooted automatically and the parameter changes will NOT be applied during the next maintenance window.

    Default: Uses existing setting

    Constraints: The DB parameter group must be in the same DB parameter group family as this DB instance.

  • :backup_retention_period (Integer) —

    The number of days to retain automated backups. Setting this parameter to a positive number enables backups. Setting this parameter to 0 disables automated backups.

    Changing this parameter can result in an outage if you change from 0 to a non-zero value or from a non-zero value to 0. These changes are applied during the next maintenance window unless the ‘ApplyImmediately` parameter is set to `true` for this request. If you change the parameter from one non-zero value to another non-zero value, the change is asynchronously applied as soon as possible.

    **Amazon Aurora**

    Not applicable. The retention period for automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

    Default: Uses existing setting

    Constraints:

    • Must be a value from 0 to 35

    • Can be specified for a MySQL Read Replica only if the source is running MySQL 5.6

    • Can be specified for a PostgreSQL Read Replica only if the source is running PostgreSQL 9.3.5

    • Cannot be set to 0 if the DB instance is a source to Read Replicas

  • :preferred_backup_window (String) —

    The daily time range during which automated backups are created if automated backups are enabled, as determined by the ‘BackupRetentionPeriod` parameter. Changing this parameter doesn’t result in an outage and the change is asynchronously applied as soon as possible.

    **Amazon Aurora**

    Not applicable. The daily time range for creating automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

    Constraints:

    • Must be in the format hh24:mi-hh24:mi

    • Must be in Universal Time Coordinated (UTC)

    • Must not conflict with the preferred maintenance window

    • Must be at least 30 minutes

  • :preferred_maintenance_window (String) —

    The weekly time range (in UTC) during which system maintenance can occur, which might result in an outage. Changing this parameter doesn’t result in an outage, except in the following situation, and the change is asynchronously applied as soon as possible. If there are pending actions that cause a reboot, and the maintenance window is changed to include the current time, then changing this parameter will cause a reboot of the DB instance. If moving this window to the current time, there must be at least 30 minutes between the current time and end of the window to ensure pending changes are applied.

    Default: Uses existing setting

    Format: ddd:hh24:mi-ddd:hh24:mi

    Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun

    Constraints: Must be at least 30 minutes

  • :multi_az (Boolean) —

    Specifies if the DB instance is a Multi-AZ deployment. Changing this parameter doesn’t result in an outage and the change is applied during the next maintenance window unless the ‘ApplyImmediately` parameter is set to `true` for this request.

  • :engine_version (String) —

    The version number of the database engine to upgrade to. Changing this parameter results in an outage and the change is applied during the next maintenance window unless the ‘ApplyImmediately` parameter is set to `true` for this request.

    For major version upgrades, if a nondefault DB parameter group is currently in use, a new DB parameter group in the DB parameter group family for the new engine version must be specified. The new DB parameter group can be the default for that DB parameter group family.

    For information about valid engine versions, see CreateDBInstance, or call DescribeDBEngineVersions.

  • :allow_major_version_upgrade (Boolean) —

    Indicates that major version upgrades are allowed. Changing this parameter doesn’t result in an outage and the change is asynchronously applied as soon as possible.

    Constraints: This parameter must be set to true when specifying a value for the EngineVersion parameter that is a different major version than the DB instance’s current version.

  • :auto_minor_version_upgrade (Boolean) —

    Indicates that minor version upgrades are applied automatically to the DB instance during the maintenance window. Changing this parameter doesn’t result in an outage except in the following case and the change is asynchronously applied as soon as possible. An outage will result if this parameter is set to ‘true` during the maintenance window, and a newer minor version is available, and RDS has enabled auto patching for that engine version.

  • :license_model (String) —

    The license model for the DB instance.

    Valid values: ‘license-included` | `bring-your-own-license` | `general-public-license`

  • :iops (Integer) —

    The new Provisioned IOPS (I/O operations per second) value for the RDS instance.

    Changing this setting doesn’t result in an outage and the change is applied during the next maintenance window unless the ‘ApplyImmediately` parameter is set to `true` for this request. If you are migrating from Provisioned IOPS to standard storage, set this value to 0. The DB instance will require a reboot for the change in storage type to take effect.

    If you choose to migrate your DB instance from using standard storage to using Provisioned IOPS, or from using Provisioned IOPS to using standard storage, the process can take time. The duration of the migration depends on several factors such as database load, storage size, storage type (standard or Provisioned IOPS), amount of IOPS provisioned (if any), and the number of prior scale storage operations. Typical migration times are under 24 hours, but the process can take up to several days in some cases. During the migration, the DB instance is available for use, but might experience performance degradation. While the migration takes place, nightly backups for the instance are suspended. No other Amazon RDS operations can take place for the instance, including modifying the instance, rebooting the instance, deleting the instance, creating a Read Replica for the instance, and creating a DB snapshot of the instance.

    Constraints: For MariaDB, MySQL, Oracle, and PostgreSQL, the value supplied must be at least 10% greater than the current value. Values that are not at least 10% greater than the existing value are rounded up so that they are 10% greater than the current value.

    Default: Uses existing setting

  • :option_group_name (String) —

    Indicates that the DB instance should be associated with the specified option group. Changing this parameter doesn’t result in an outage except in the following case and the change is applied during the next maintenance window unless the ‘ApplyImmediately` parameter is set to `true` for this request. If the parameter change results in an option group that enables OEM, this change can cause a brief (sub-second) period during which new connections are rejected but existing connections are not interrupted.

    Permanent options, such as the TDE option for Oracle Advanced Security TDE, can’t be removed from an option group, and that option group can’t be removed from a DB instance once it is associated with a DB instance

  • :new_db_instance_identifier (String) —

    The new DB instance identifier for the DB instance when renaming a DB instance. When you change the DB instance identifier, an instance reboot will occur immediately if you set ‘Apply Immediately` to true, or will occur during the next maintenance window if `Apply Immediately` to false. This value is stored as a lowercase string.

    Constraints:

    • Must contain from 1 to 63 letters, numbers, or hyphens.

    • The first character must be a letter.

    • Cannot end with a hyphen or contain two consecutive hyphens.

    Example: ‘mydbinstance`

  • :storage_type (String) —

    Specifies the storage type to be associated with the DB instance.

    If you specify Provisioned IOPS (‘io1`), you must also include a value for the `Iops` parameter.

    If you choose to migrate your DB instance from using standard storage to using Provisioned IOPS, or from using Provisioned IOPS to using standard storage, the process can take time. The duration of the migration depends on several factors such as database load, storage size, storage type (standard or Provisioned IOPS), amount of IOPS provisioned (if any), and the number of prior scale storage operations. Typical migration times are under 24 hours, but the process can take up to several days in some cases. During the migration, the DB instance is available for use, but might experience performance degradation. While the migration takes place, nightly backups for the instance are suspended. No other Amazon RDS operations can take place for the instance, including modifying the instance, rebooting the instance, deleting the instance, creating a Read Replica for the instance, and creating a DB snapshot of the instance.

    Valid values: ‘standard | gp2 | io1`

    Default: ‘io1` if the `Iops` parameter is specified, otherwise `standard`

  • :tde_credential_arn (String) —

    The ARN from the key store with which to associate the instance for TDE encryption.

  • :tde_credential_password (String) —

    The password for the given ARN from the key store in order to access the device.

  • :ca_certificate_identifier (String) —

    Indicates the certificate that needs to be associated with the instance.

  • :domain (String) —

    The Active Directory Domain to move the instance to. Specify ‘none` to remove the instance from its current domain. The domain must be created prior to this operation. Currently only a Microsoft SQL Server instance can be created in a Active Directory Domain.

  • :copy_tags_to_snapshot (Boolean) —

    True to copy all tags from the DB instance to snapshots of the DB instance, and otherwise false. The default is false.

  • :monitoring_interval (Integer) —

    The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the DB instance. To disable collecting Enhanced Monitoring metrics, specify 0. The default is 0.

    If ‘MonitoringRoleArn` is specified, then you must also set `MonitoringInterval` to a value other than 0.

    Valid Values: ‘0, 1, 5, 10, 15, 30, 60`

  • :db_port_number (Integer) —

    The port number on which the database accepts connections.

    The value of the ‘DBPortNumber` parameter must not match any of the port values specified for options in the option group for the DB instance.

    Your database will restart when you change the ‘DBPortNumber` value regardless of the value of the `ApplyImmediately` parameter.

    MySQL

    Default: ‘3306`

    Valid Values: ‘1150-65535`

    MariaDB

    Default: ‘3306`

    Valid Values: ‘1150-65535`

    Valid Values: ‘1150-65535` except for `1434`, `3389`, `47001`, `49152`, and `49152` through `49156`.

    **Amazon Aurora**

    Default: ‘3306`

    Valid Values: ‘1150-65535`

  • :publicly_accessible (Boolean) —

    Boolean value that indicates if the DB instance has a publicly resolvable DNS name. Set to ‘True` to make the DB instance Internet-facing with a publicly resolvable DNS name, which resolves to a public IP address. Set to `False` to make the DB instance internal with a DNS name that resolves to a private IP address.

    ‘PubliclyAccessible` only applies to DB instances in a VPC. The DB instance must be part of a public subnet and `PubliclyAccessible` must be true in order for it to be publicly accessible.

    Changes to the ‘PubliclyAccessible` parameter are applied immediately regardless of the value of the `ApplyImmediately` parameter.

    Default: false

  • :monitoring_role_arn (String) —

    The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to Amazon CloudWatch Logs. For example, ‘arn:aws:iam:123456789012:role/emaccess`. For information on creating a monitoring role, go to [To create an IAM role for Amazon RDS Enhanced Monitoring].

    If ‘MonitoringInterval` is set to a value other than 0, then you must supply a `MonitoringRoleArn` value.

#wait_until(options = {}, &block) ⇒ Resource

Deprecated.

Use [Aws::RDS::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged

Waiter polls an API operation until a resource enters a desired state.

## Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

## Example

instance.wait_until(max_attempts:10, delay:5) {|instance| instance.state.name == 'running' }

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

## Callbacks

You can be notified before each polling attempt and before each delay. If you throw ‘:success` or `:failure` from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

## Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10 —

    Maximum number of

  • :delay (Integer) — default: 10 —

    Delay between each

  • :before_attempt (Proc) — default: nil —

    Callback

  • :before_wait (Proc) — default: nil —

    Callback

Returns:

  • (Resource) —

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError) —

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError) —

    Raised when the resource does not
