PutFunctionConcurrencyRequest Class

Container for the parameters to the PutFunctionConcurrency operation. Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level.

Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function.

Use GetAccountSettings to see your Regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren't configured with a per-function limit. For more information, see Lambda function scaling.

Properties

Name Type Description

	Name	Type	Description
	FunctionName	System.String	Gets and sets the property FunctionName. The name or ARN of the Lambda function. Name formats Function name – `my-function`. Function ARN – `arn:aws:lambda:us-west-2:123456789012:function:my-function`. Partial ARN – `123456789012:function:my-function`. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.
	ReservedConcurrentExecutions	System.Int32	Gets and sets the property ReservedConcurrentExecutions. The number of simultaneous executions to reserve for the function.

FunctionName

System.String

Gets and sets the property FunctionName.

The name or ARN of the Lambda function.

Name formats

Function name – my-function.
Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.
Partial ARN – 123456789012:function:my-function.

The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

ReservedConcurrentExecutions

System.Int32

Gets and sets the property ReservedConcurrentExecutions.

The number of simultaneous executions to reserve for the function.

Examples

The following example configures 100 reserved concurrent executions for the my-function function.

To configure a reserved concurrency limit for a function


var response = client.PutFunctionConcurrency(new PutFunctionConcurrencyRequest 
{
    FunctionName = "my-function",
    ReservedConcurrentExecutions = 100
});

int reservedConcurrentExecutions = response.ReservedConcurrentExecutions;
