Struct aws_sdk_lambda::operation::create_event_source_mapping::builders::CreateEventSourceMappingFluentBuilder

pub struct CreateEventSourceMappingFluentBuilder { /* private fields */ }

Fluent builder constructing a request to CreateEventSourceMapping.

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.

• Amazon DynamoDB Streams

• Amazon Kinesis

• Amazon SQS

• Amazon MQ and RabbitMQ

• Amazon MSK

• Apache Kafka

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

• Amazon Kinesis

• Amazon SQS

• Amazon MQ and RabbitMQ

• Amazon MSK

• Apache Kafka

Implementations

impl CreateEventSourceMappingFluentBuilder

pub async fn customize( self ) -> Result<CustomizableOperation<CreateEventSourceMapping, AwsResponseRetryClassifier>, SdkError<CreateEventSourceMappingError>>

Consume this builder, creating a customizable operation that can be modified before being sent. The operation’s inner http::Request can be modified as well.

pub async fn send( self ) -> Result<CreateEventSourceMappingOutput, SdkError<CreateEventSourceMappingError>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

Default: True

pub fn batch_size(self, input: i32) -> Self

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 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.

pub fn set_batch_size(self, input: Option<i32>) -> Self

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 10,000.

pub fn filter_criteria(self, input: FilterCriteria) -> Self

An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

pub fn set_filter_criteria(self, input: Option<FilterCriteria>) -> Self

pub fn maximum_batching_window_in_seconds(self, input: i32) -> Self

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 streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, and Amazon MQ 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.

Related setting: For streams and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

pub fn set_maximum_batching_window_in_seconds(self, input: Option<i32>) -> Self
