Something we will follow:

  • for unknown attributes in the request, we will throw an error with a whole list of all of them

  • for all the response, we prefer HATEOAS, such as: return resource link in the response of create/update/delete; add resource url for sub resources(region/indexes)

  • http status code: 201 and 409 for create, 200 and 404 for delete,  200 and 404 for put to update

  • camelCase is for all the key in the request and response body

Long running request:

Rebalance

rebalance request and response:

POST https://localhost/operations/rebalance

HTTP/1.1 202 Accepted
Location: https://localhost/operations/12336





POST https://localhost/operations/rebalance

HTTP/1.1 202 Accepted
Location: https://localhost/operations/12336

  POST https://localhost/operations/rebalance

  HTTP/1.1 202 Accepted
  Location: https://localhost/operations/12336

subsequent rebalance request would get the same result: (if a rebalance is already going on, the request is simply accepted, and returns the running rebalance's operation status link)

if the previous rebalance request is already finished, a new rebalance will be triggered, and a new operation status link will be sent back to the user


status request: http GET https://localhost/operations/12336

response of running rebalance: 


HTTP/1.1 200 OK

{
  "operationType": "rebalance",
  "startTime": "1287364876",
  "status": "RUNNING",
  "cancelMethod": "delete",
  "cancelLink" : "/operations/12356"
}


response of a finished rebalance : 200 Ok,

{ "operationType": "rebalance", "startTime": "1287364876", "endTime" : "232353232", "status": "successful" }


cancel request: http DELETE https://localhost/operations/12336

response:  200 Ok. { "operationType": "rebalance", "startTime": "1287364876", "endTime" : "232353232", "status": "cancelled" }

if it's already finished, the response should be: { "operationType": "rebalance", "startTime": "1287364876", "endTime" : "232353232", "status": "successful" }
