Creates an activity. An activity is a task that you write in any
programming language and host on any machine that has access to AWS Step
Functions. Activities must poll Step Functions using the
get_activity_task API action and respond
using SendTask* API actions. This function lets Step Functions know
the existence of your activity and returns an identifier for use in a
state machine and when polling from the activity.
This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.
create_activity is an idempotent API.
Subsequent requests won<U+2019>t create a duplicate resource if it was already
created. create_activity's idempotency check is
based on the activity name. If a following request has different
tags values, Step Functions will ignore these differences and treat it
as an idempotent request of the previous. In this case, tags will not
be updated, even if they are different.
sfn_create_activity(name, tags)[required] The name of the activity to create. This name must be unique for your AWS account and region for 90 days. For more information, see Limits Related to State Machine Executions in the AWS Step Functions Developer Guide.
A name must not contain:
white space
brackets < > { } [ ]
wildcard characters ? *
special characters \" # % \ ^ | ~ \` $ & , ; : /
control characters (U+0000-001F, U+007F-009F)
To enable logging with CloudWatch Logs, the name should only contain 0-9, A-Z, a-z, - and _.
[ ]: R:%20
The list of tags to add to a resource.
An array of key-value pairs. For more information, see Using Cost Allocation Tags in the AWS Billing and Cost Management User Guide, and Controlling Access Using IAM Tags.
Tags may only contain Unicode letters, digits, white space, or these
symbols: _ . : / = + - @.
A list with the following syntax:
list(
activityArn = "string",
creationDate = as.POSIXct(
"2015-01-01"
)
)
svc$create_activity(
name = "string",
tags = list(
list(
key = "string",
value = "string"
)
)
)
