AWS API Changes

2019/12/04 - AWS Lambda - 5 new api methods

Changes - Added the ProvisionedConcurrency type and operations. Allocate provisioned concurrency to enable your function to scale up without fluctuations in latency. Use PutProvisionedConcurrencyConfig to configure provisioned concurrency on a version of a function, or on an alias.

DeleteProvisionedConcurrencyConfig (new)

Link ¶

Deletes the provisioned concurrency configuration for a function.

See also: AWS API Documentation

Request Syntax

client.delete_provisioned_concurrency_config(
    FunctionName='string',
    Qualifier='string'
)

type FunctionName

string

param FunctionName

[REQUIRED]

The name 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.

type Qualifier

string

param Qualifier

[REQUIRED]

The version number or alias name.

returns

None

ListProvisionedConcurrencyConfigs (new)
