Wait for function_exists.
Parameters:
-
function_name
(NamespacedFunctionName)
–
The name or ARN of the Lambda function, version, or alias.
Name formats
-
Function name – my-function (name-only), my-function:v1 (with alias).
-
Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.
-
Partial ARN – 123456789012:function:my-function.
You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.
-
max_wait_time
(float)
–
Maximum total seconds to wait before raising WaiterTimeoutError.
-
min_delay
(float, default:
1
)
–
Minimum seconds between operation attempts (spec default 2).
-
max_delay
(float, default:
20
)
–
Maximum seconds between operation attempts (spec default 120).
-
qualifier
(Optional[NumericLatestPublishedOrAliasQualifier], default:
None
)
–
Specify a version or alias to get details about a published version of the function.
