delete-event-source-mapping

Description

Deletes an event source mapping . You can get the identifier of a mapping from the output of ListEventSourceMappings .

When you delete an event source mapping, it enters a Deleting state and might not be completely deleted for several seconds.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  delete-event-source-mapping
--uuid <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--uuid (string)

The identifier of the event source mapping.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

To delete the mapping between an event source and an AWS Lambda function

The following delete-event-source-mapping example deletes the mapping between an SQS queue and the my-function Lambda function.

aws lambda delete-event-source-mapping \
    --uuid  a1b2c3d4-5678-90ab-cdef-11111EXAMPLE

Output:

{
    "UUID": "a1b2c3d4-5678-90ab-cdef-11111EXAMPLE",
    "StateTransitionReason": "USER_INITIATED",
    "LastModified": 1569285870.271,
    "BatchSize": 5,
    "State": "Deleting",
    "FunctionArn": "arn:aws:lambda:us-west-2:123456789012:function:my-function",
    "EventSourceArn": "arn:aws:sqs:us-west-2:123456789012:mySQSqueue"
}

Output

UUID -> (string)

The identifier of the event source mapping.

StartingPosition -> (string)

The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK stream sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams.

StartingPositionTimestamp -> (timestamp)

With StartingPosition set to AT_TIMESTAMP , the time from which to start reading.

BatchSize -> (integer)

The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

Default value: Varies by service. For Amazon SQS, the default is 10. For all other services, the default is 100.

Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

MaximumBatchingWindowInSeconds -> (integer)

(Streams and Amazon SQS standard queues) The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function.

Default: 0

Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

ParallelizationFactor -> (integer)

(Streams only) The number of batches to process concurrently from each shard. The default value is 1.

EventSourceArn -> (string)

The Amazon Resource Name (ARN) of the event source.

FunctionArn -> (string)

The ARN of the Lambda function.

LastModified -> (timestamp)

The date that the event source mapping was last updated or that its state changed.

LastProcessingResult -> (string)

The result of the last Lambda invocation of your function.

State -> (string)

The state of the event source mapping. It can be one of the following: Creating , Enabling , Enabled , Disabling , Disabled , Updating , or Deleting .

StateTransitionReason -> (string)

Indicates whether a user or Lambda made the last change to the event source mapping.

DestinationConfig -> (structure)

(Streams only) An Amazon SQS queue or Amazon SNS topic destination for discarded records.

OnSuccess -> (structure)

The destination configuration for successful invocations.

Destination -> (string)

The Amazon Resource Name (ARN) of the destination resource.

OnFailure -> (structure)

The destination configuration for failed invocations.

Destination -> (string)

The Amazon Resource Name (ARN) of the destination resource.

Topics -> (list)

The name of the Kafka topic.

(string)

Queues -> (list)

(Amazon MQ) The name of the Amazon MQ broker destination queue to consume.

(string)

SourceAccessConfigurations -> (list)

An array of the authentication protocol, VPC components, or virtual host to secure and define your event source.

(structure)

To secure and define access to your event source, you can specify the authentication protocol, VPC components, or virtual host.

Type -> (string)

The type of authentication protocol, VPC components, or virtual host for your event source. For example: "Type":"SASL_SCRAM_512_AUTH" .

• BASIC_AUTH - (Amazon MQ) The Secrets Manager secret that stores your broker credentials.

• BASIC_AUTH - (Self-managed Apache Kafka) The Secrets Manager ARN of your secret key used for SASL/PLAIN authentication of your Apache Kafka brokers.

• VPC_SUBNET - The subnets associated with your VPC. Lambda connects to these subnets to fetch data from your self-managed Apache Kafka cluster.

• VPC_SECURITY_GROUP - The VPC security group used to manage access to your self-managed Apache Kafka brokers.

• SASL_SCRAM_256_AUTH - The Secrets Manager ARN of your secret key used for SASL SCRAM-256 authentication of your self-managed Apache Kafka brokers.

• SASL_SCRAM_512_AUTH - The Secrets Manager ARN of your secret key used for SASL SCRAM-512 authentication of your self-managed Apache Kafka brokers.

• VIRTUAL_HOST - (Amazon MQ) The name of the virtual host in your RabbitMQ broker. Lambda uses this RabbitMQ host as the event source.

URI -> (string)

The value for your chosen configuration in Type . For example: "URI": "arn:aws:secretsmanager:us-east-1:01234567890:secret:MyBrokerSecretName" .

SelfManagedEventSource -> (structure)

The self-managed Apache Kafka cluster for your event source.

Endpoints -> (map)

The list of bootstrap servers for your Kafka brokers in the following format: "KAFKA_BOOTSTRAP_SERVERS": ["abc.xyz.com:xxxx","abc2.xyz.com:xxxx"] .

key -> (string)

value -> (list)

(string)

MaximumRecordAgeInSeconds -> (integer)

(Streams only) Discard records older than the specified age. The default value is -1, which sets the maximum age to infinite. When the value is set to infinite, Lambda never discards old records.

BisectBatchOnFunctionError -> (boolean)

(Streams only) If the function returns an error, split the batch in two and retry. The default value is false.

MaximumRetryAttempts -> (integer)

(Streams only) Discard records after the specified number of retries. The default value is -1, which sets the maximum number of retries to infinite. When MaximumRetryAttempts is infinite, Lambda retries failed records until the record expires in the event source.

TumblingWindowInSeconds -> (integer)

(Streams only) The duration in seconds of a processing window. The range is 1–900 seconds.

FunctionResponseTypes -> (list)

(Streams only) A list of current response type enums applied to the event source mapping.

(string)
