Method Detail

builder

public static AWSLambdaClientBuilder builder()

addPermission

public AddPermissionResult addPermission(AddPermissionRequest request)

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 the 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.

Permissions apply to the Amazon Resource Name (ARN) used to invoke the function, which can be unqualified (the unpublished version of the function), or include a version or alias. If a client uses a version or alias to invoke a function, use the Qualifier parameter to apply permissions to that ARN. For more information about versioning, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:AddPermission action.

Specified by:

addPermission in interface AWSLambda

Parameters:

addPermissionRequest -

Returns:

Result of the AddPermission operation returned by the service.

Throws:

ServiceException - The AWS Lambda service encountered an internal error.

ResourceNotFoundException - The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.

ResourceConflictException - The resource already exists.

InvalidParameterValueException - One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception.

PolicyLengthExceededException - Lambda function access policy is limited to 20 KB.

TooManyRequestsException - Request throughput limit exceeded

PreconditionFailedException - The RevisionId provided does not match the latest RevisionId for the Lambda function or alias. Call the GetFunction or the GetAlias API to retrieve the latest RevisionId for your resource.

Invokes a Lambda function. For an example, see Create the Lambda Function and Test It Manually.

Specify just a function name to invoke the latest version of the function. To invoke a published version, use the Qualifier parameter to specify a version or alias.

If you use the RequestResponse (synchronous) invocation option, the function will be invoked only once. If you use the Event (asynchronous) invocation option, the function will be invoked at least once in response to an event and the function must be idempotent to handle this.

For functions with a long timeout, your client may be disconnected during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.

This operation requires permission for the lambda:InvokeFunction action.

The TooManyRequestsException noted below will return the following: ConcurrentInvocationLimitExceeded will be returned if you have no functions with reserved concurrency and have exceeded your account concurrent limit or if a function without reserved concurrency exceeds the account's unreserved concurrency limit.

If you are using the versioning feature, you can list all of your functions or only $LATEST versions. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases.

putFunctionConcurrency

public PutFunctionConcurrencyResult putFunctionConcurrency(PutFunctionConcurrencyRequest request)

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. For more information, see Managing Concurrency.

Specified by:

putFunctionConcurrency in interface AWSLambda

Parameters:

putFunctionConcurrencyRequest -

Returns:

Result of the PutFunctionConcurrency operation returned by the service.

Throws:

ServiceException - The AWS Lambda service encountered an internal error.

InvalidParameterValueException - One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception.

removePermission

public RemovePermissionResult removePermission(RemovePermissionRequest request)

Removes permissions from a function. 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. When you remove permissions, disable the event source mapping or trigger configuration first to avoid errors.

Permissions apply to the Amazon Resource Name (ARN) used to invoke the function, which can be unqualified (the unpublished version of the function), or include a version or alias. If a client uses a version or alias to invoke a function, use the Qualifier parameter to apply permissions to that ARN. For more information about versioning, see AWS Lambda Function Versioning and Aliases.

You need permission for the lambda:RemovePermission action.

Specified by:

removePermission in interface AWSLambda

Parameters:

removePermissionRequest -

Returns:

Result of the RemovePermission operation returned by the service.

Throws:

ServiceException - The AWS Lambda service encountered an internal error.

ResourceNotFoundException - The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.

InvalidParameterValueException - One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception.

TooManyRequestsException - Request throughput limit exceeded

PreconditionFailedException - The RevisionId provided does not match the latest RevisionId for the Lambda function or alias. Call the GetFunction or the GetAlias API to retrieve the latest RevisionId for your resource.

getCachedResponseMetadata

public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.

Specified by:

getCachedResponseMetadata in interface AWSLambda

Parameters:

request - The originally executed request

Returns:

The response metadata for the specified request, or null if none is available.
