Problem Statement
...
Solution approach to overcome the problem has below componentsapproaches
APPROACH 1
- Sunbird Platform will expose an API for end user to initiate update content
- Sunbird Platform will log the request in DB and pass the user a generated process Id
- Sunbird Platform will send the request with processId to kafka message queue
- Request will be picked up by Learning platform and would start the processing of update content based on the request
- Sunbird Platform will use a listener to get the status update from the kafka based on processId
Approach 2
- Sunbird Platform will expose an API for end user to initiate update content
- Sunbird Platform will internally call Content Service with the request provided by User
- Content Service will validate the request
- With valid request, Content Service will initiate the update process through kafka pipeline and will return unique process ID identifying the process.
- With Invalid request, Content Service will return error message which Sunbird platform will return to User
- For valid response from Content Service, processId with other details will be saved in Sunbird platform DB
pros and cons of both approaches
| approaches | pros | cons |
|---|---|---|
1.without content service | loosely coupled | |
| 2.with content service |
Problem Statement
What is the API for update content?
...
X-authenticated-user-token
Request Params:
| name | type | description |
|---|---|---|
| script | String | name of the script to be run by Content Service |
| version | String | the version of the script |
| content | Map | additional parameters which would work as arguments for the scripts |
Response Params:
| name | type | description |
|---|---|---|
| processId | String | unique identifier of the process started for the request, needed to get the status of the process |
Errors:
| status code | error code | error message |
|---|---|---|

"result": {
"processId" : "01262366359399628812"
}
}

...
content_update_process table structure should be as below
| column | type | description |
|---|---|---|
| id | text | holds process id |
| script | text | name of the script to run |
| version | text | the version of the script |
| request | text | holds the input request as it is |
| status | text | the status last received from content service |
| message | text | message from content service in case of failure |
| createdby | text | userid of one who invoked the process |
| createdat | timestamp | when the process was started |
| updatedat | timestamp | when the process was last updated |
