how do i save state or status transitions against a unique id in Elasticsearch-CodePudding

I am new to elasticsearch and working on POC of a solution. I have a use-case wherein i want to keep track of state changes of a ticket. The ticket id is the unique identifier for the data. I want to save the status changes, the time when status is changes and the comments on the ticket.

What is the best way to implement this?

I am saving my ticket data in an index with mapping defined as below:

"mappings": {
    "properties":
        {
            "ticket_id": { "type": "keyword" },
            "Problem Description": { "type": "text" },
            "start_time" :{"type": "date","format":"yyyy-MM-dd HH:mm:ss"},
            "end_time" :{"type": "date","format":"yyyy-MM-dd HH:mm:ss"},
            "workflow_status":{"type": "text" }
        }
}

Its difficult to visualise the problem and explain the solution without data, hence I created below data to explain it better:

Index Sample data

// below document doesn't marks the status to `done` hence just the `start_time` change with Description.

{
    "ticket_id" : "jira-001",
    "Problem_Description" : "this is first jira-001",
    "start_time" : "2022-09-14 05:30:00",
    "workflow_status" : "backlog"
}

// below document doesn't marks the status to `done` hence just the `start_time` change with Description.


{
    "ticket_id" : "jira-001",
    "Problem_Description" : "working on jira-001",
    "start_time" : "2022-09-14 07:30:00",
    "workflow_status" : "in-progress"
}

// below document marks the status to `done` hence `end_time` 
{
    "ticket_id" : "jira-001",
    "Problem_Description" : "completed jira-001",
    "start_time" : "2022-09-15 01:30:00",
    "end_time" : "2022-09-15 04:30:00",
    "workflow_status" : "done"
}

After that when you want to get all the workflow of same ticket jira-001 in my example, you can use below query to fetch that sort based on their start_time

{
    "size": 10,
    "query": {
        "term": {
            "ticket_id": "jira-001"
        }
    },
    "sort": [
        {
            "start_time": "asc"
        }
    ]
}

This will give below result, Hope this helps and is according to your use-case.
