Process In Order#

Ensures that payloads are processed in order across executions according to an ordering specified by a payload attribute. Returns the largest possible set of ordered payloads on the Process branch, and otherwise follows the Skip branch and returns the current item. | key: processInOrder

Input	Notes	Example
Input Collection ID string / Required	Notes A value that uniquely identifies the collection that is being processed out of order.	Example da41e39f-ea4d-435a-b922-c6aae3915ebe
Input Collection Length data / Required	Notes The number of items in the collection. When processing is finished the interim data for the collection is removed.	Example 100
Input Item data / Required	Notes The current item to consider for processing.	Example { Index: 0, Name: "Acme Contracting" }
Input Item Index data / Required	Notes The integer value to consider as the index for the current item that specifies intended processing order. 0 is the first index value.	Example 10

The Process In Order action allows you to send several requests to an instance out of order, and helps to ensure that data runs through your integration in order. Requests with data payloads are collected, and when an ordered set of requests have been received this action processes the requests in the order you specify.

In order to use this action, you will need to know how many total items you are sending ahead of time.

Example: suppose we are updating an inventory system with three updates, and order is important. We want to process widgets first, then gadgets, and finally whatsits. We know that we have three items to import, and due to limitations of our third-party system we can't send them all at once. We're not confident that they'll arrive to Prismatic in any particular order, so we'll use this action to help.

Collection Tools - Process in Order flow in Prismatic integration designer

We'll come up with a unique "Collection ID", and begin sending our data in any order:

$ curl 'https://hooks.prismatic.io/trigger/EXAMPLE==' \    --header "Content-Type: application/json" \    --data '{"item": "whatsits", "index": 2}' \    --header 'collectionid: abc-123' \    --header 'collectionlength: 3'
$ curl 'https://hooks.prismatic.io/trigger/EXAMPLE==' \    --header "Content-Type: application/json" \    --data '{"item": "widgets", "index": 0}' \    --header 'collectionid: abc-123' \    --header 'collectionlength: 3'
$ curl 'https://hooks.prismatic.io/trigger/EXAMPLE==' \    --header "Content-Type: application/json" \    --data '{"item": "gadgets", "index": 1}' \    --header 'collectionid: abc-123' \    --header 'collectionlength: 3'

The first time that our integration is invoked, the {"item": "whatsits", "index": 2} payload will be stored for future processing, since items with index 0 and 1 have not yet been processed.

The second time that our integration is invoked, the {"item": "widgets", "index": 0} payload will be processed immediately, since it has index 0, but then our loop will stop since an item with index 1 has not yet been received.

The third time our integration is invoked, the {"item": "gadgets", "index": 1} will be processed right away, since it has index 1 and an item with index 0 has already been processed. The {"item": "whatsits", "index": 2} payload will also be pulled from storage and processed since it is next in line to be processed.

At this point all items will have been processed.

Note: Items must be zero-indexed.

Output Example Payload#

{  "data": [    {      "Index": 0,      "Name": "Acme Contracting"    },    {      "Index": 1,      "Name": "FooBar Consulting"    }  ],  "instanceState": {    "7d577253-3ef0-4a0a-bb7f-8335c2596e70": {      "da41e39f-ea4d-435a-b922-c6aae3915ebe": {        "lastIndex": 1,        "items": []      }    }  },  "branch": "Process"}
