create-event-source-mapping

Description

Creates a mapping between an event source and an Lambda function. Lambda reads items from the event source and invokes the function.

For details about how to configure different event sources, see the following topics.

The following error handling options are available only for stream sources (DynamoDB and Kinesis):

  • BisectBatchOnFunctionError – If the function returns an error, split the batch in two and retry.
  • DestinationConfig – Send discarded records to an Amazon SQS queue or Amazon SNS topic.
  • MaximumRecordAgeInSeconds – Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires
  • MaximumRetryAttempts – Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.
  • ParallelizationFactor – Process multiple batches from each shard concurrently.

For information about which configuration parameters apply to each event source, see the following topics.

  • Amazon DynamoDB Streams – Default 100. Max 10,000.
  • Amazon Simple Queue Service – Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.
  • Amazon Managed Streaming for Apache Kafka – Default 100. Max 10,000.
  • Self-managed Apache Kafka – Default 100. Max 10,000.
  • Amazon MQ (ActiveMQ and RabbitMQ) – Default 100. Max 10,000.
  • DocumentDB – Default 100. Max 10,000.

--maximum-batching-window-in-seconds (integer)

The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new 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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To create a mapping between an event source and an AWS Lambda function

The following create-event-source-mapping example creates a mapping between an SQS queue and the my-function Lambda function.

aws lambda create-event-source-mapping \
    --function-name my-function \
    --batch-size 5 \
    --event-source-arn arn:aws:sqs:us-west-2:123456789012:mySQSqueue

Output:

{
    "UUID": "a1b2c3d4-5678-90ab-cdef-11111EXAMPLE",
    "StateTransitionReason": "USER_INITIATED",
    "LastModified": 1569284520.333,
    "BatchSize": 5,
    "State": "Creating",
    "FunctionArn": "arn:aws:lambda:us-west-2:123456789012:function:my-function",
    "EventSourceArn": "arn:aws:sqs:us-west-2:123456789012:mySQSqueue"
}

For more information, see AWS Lambda Event Source Mapping in the AWS Lambda Developer Guide.
