Classes

NameDescription
Class AccountLimit

Provides limits of code size and concurrency associated with the current account and region.

Class AccountUsage

Provides code size usage and function count associated with the current account and region.

Class AddPermissionRequest

Container for the parameters to the AddPermission operation. Adds a permission to the resource policy associated with the specified AWS Lambda function. You use resource policies to grant permissions to event sources that use push model. In a push model, event sources (such as Amazon S3 and custom applications) invoke your Lambda function. Each permission you add to the resource policy allows an event source, permission to invoke the Lambda function.

For information about the push model, see AWS Lambda: How it Works.

If you are using versioning, the permissions you add are specific to the Lambda function version or alias you specify in the AddPermission request via the Qualifier parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:AddPermission action.

Class AddPermissionResponse

Class AliasConfiguration

Provides configuration information about a Lambda function version alias.

Class AliasRoutingConfiguration

Class CreateAliasRequest

Container for the parameters to the CreateAlias operation. Creates an alias that points to the specified Lambda function version. For more information, see Introduction to AWS Lambda Aliases.

Alias names are unique for a given function. This requires permission for the lambda:CreateAlias action.

Class CreateAliasResponse

Provides configuration information about a Lambda function version alias.

Class CreateEventSourceMappingRequest

Container for the parameters to the CreateEventSourceMapping operation. Identifies a stream as an event source for a Lambda function. It can be either an Amazon Kinesis stream or an Amazon DynamoDB stream. AWS Lambda invokes the specified function when records are posted to the stream.

This association between a stream source and a Lambda function is called the event source mapping.

This event source mapping is relevant only in the AWS Lambda pull model, where AWS Lambda invokes the function. For more information, see AWS Lambda: How it Works in the AWS Lambda Developer Guide.

You provide mapping information (for example, which stream to read from and which Lambda function to invoke) in the request body.

Each event source, such as an Amazon Kinesis or a DynamoDB stream, can be associated with multiple AWS Lambda function. A given Lambda function can be associated with multiple AWS event sources.

If you are using versioning, you can specify a specific function version or an alias via the function name parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:CreateEventSourceMapping action.

Class CreateEventSourceMappingResponse

Class PutFunctionConcurrencyRequest

Container for the parameters to the PutFunctionConcurrency operation. Sets a limit on the number of concurrent executions available to this function. It is a subset of your account's total concurrent execution limit per region. Note that Lambda automatically reserves a buffer of 100 concurrent executions for functions without any reserved concurrency limit. This means if your account limit is 1000, you have a total of 900 available to allocate to individual functions.

Class PutFunctionConcurrencyResponse

This is the response object from the PutFunctionConcurrency operation.

Class RemovePermissionRequest

Container for the parameters to the RemovePermission operation. You can remove individual permissions from an resource policy associated with a Lambda function by providing a statement ID that you provided when you added the permission.

Class UpdateAliasResponse

Provides configuration information about a Lambda function version alias.

Class UpdateEventSourceMappingRequest

Container for the parameters to the UpdateEventSourceMapping operation. You can update an event source mapping. This is useful if you want to change the parameters of the existing mapping without losing your position in the stream. You can change which function will receive the stream records, but to change the stream itself, you must create a new mapping.

If you are using the versioning feature, you can update the event source mapping to map to a specific Lambda function version or alias as described in the FunctionName parameter. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases.

If you disable the event source mapping, AWS Lambda stops polling. If you enable again, it will resume polling from the time it had stopped polling, so you don't lose processing of any records. However, if you delete event source mapping and create it again, it will reset.
