AWS API Changes

2019/11/25 - AWS Lambda - 5 new 13 updated api methods

Changes Added the function state and update status to the output of GetFunctionConfiguration and other actions. Check the state information to ensure that a function is ready before you perform operations on it. Functions take time to become ready when you connect them to a VPC.Added the EventInvokeConfig type and operations to configure error handling options for asynchronous invocation. Use PutFunctionEventInvokeConfig to configure the number of retries and the maximum age of events when you invoke the function asynchronously.Added on-failure and on-success destination settings for asynchronous invocation. Configure destinations to send an invocation record to an SNS topic, an SQS queue, an EventBridge event bus, or a Lambda function.Added error handling options to event source mappings. This enables you to configure the number of retries, configure the maximum age of records, or retry with smaller batches when an error occurs when a function processes a Kinesis or DynamoDB stream.Added the on-failure destination setting to event source mappings. This enables you to send discarded events to an SNS topic or SQS queue when all retries fail or when the maximum record age is exceeded when a function processes a Kinesis or DynamoDB stream.Added the ParallelizationFactor option to event source mappings to increase concurrency per shard when a function processes a Kinesis or DynamoDB stream.

PutFunctionEventInvokeConfig (new)

Link ¶

Configures options for asynchronous invocation on a function, version, or alias.

By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it. To retain discarded events, configure a dead-letter queue with UpdateFunctionConfiguration.

 'MaximumRecordAgeInSeconds': 'integer',
 'MaximumRetryAttempts': 'integer',
 'ParallelizationFactor': 'integer'}

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

For details about each event source type, 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.
MaximumRetryAttempts - Discard records after the specified number of retries.

Creates a Lambda function. To create a function, you need a deployment package and an execution role. The deployment package contains your function code. The execution role grants the function permission to use AWS services, such as Amazon CloudWatch Logs for log streaming and AWS X-Ray for request tracing.

When you create a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute or so. During this time, you can't invoke or modify the function. The State , StateReason , and StateReasonCode fields in the response from GetFunctionConfiguration indicate when the function is ready to invoke. For more information, see Function States.

A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration. A published version is a snapshot of your function code and configuration that can't be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the Publish parameter to create version 1 of your function from its initial configuration.

The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both the unpublished and published versions of the function, and include tags ( TagResource ) and per-function concurrency limits ( PutFunctionConcurrency ).

If another account or an AWS service invokes your function, use AddPermission to grant permission by creating a resource-based IAM policy. You can grant permissions at the function level, on a version, or on an alias.

To invoke your function directly, use Invoke. To invoke your function in response to events in other AWS services, create an event source mapping ( CreateEventSourceMapping ), or configure a function trigger in the other service. For more information, see Invoking Functions.

Creates a version from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn't change.

AWS Lambda doesn't publish a version if the function's configuration and code haven't changed since the last version. Use UpdateFunctionCode or UpdateFunctionConfiguration to update the function before publishing a version.

Clients can invoke versions directly or with an alias. To create an alias, use CreateAlias.

Updates an event source mapping. You can change the function that AWS Lambda invokes, or pause invocation and resume later from the same location.

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.
MaximumRetryAttempts - Discard records after the specified number of retries.

Modify the version-specific settings of a Lambda function.

When you update a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute. During this time, you can't modify the function, but you can still invoke it. The LastUpdateStatus , LastUpdateStatusReason , and LastUpdateStatusReasonCode fields in the response from GetFunctionConfiguration indicate when the update is complete and the function is processing events with the new configuration. For more information, see Function States.

These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version.

To configure function concurrency, use PutFunctionConcurrency. To grant invoke permissions to an account or AWS service, use AddPermission.
