Description

Creates a mapping between an event source and an Lambda function. Lambda reads items from the event source and triggers the function. For details about how to configure different event sources, see the following topics. The following error handling options are only available 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.

Parameters

-BatchSize <Int32>
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).
  • Amazon Kinesis - Default 100. Max 10,000.
  • Amazon DynamoDB Streams - Default 100. Max 1,000.
  • 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.

Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
