ASF GitHub Bot commented on KAFKA-7638:
---------------------------------------

stanislavkozlovski opened a new pull request #5932: KAFKA-7638: Add support for multiple task creation in one request
URL: https://github.com/apache/kafka/pull/5932
 
 
   [JIRA](https://issues.apache.org/jira/browse/KAFKA-7638)
   Trogdor Coordinator now supports creation of multiple tasks in one request call.
   This is exposed under `/coordinator/tasks/mass_create`
   Sample body: 
   ```json
   {"tasks": [{...}, {...}]}
   ```
   
   Additional changes:
   The /tasks/create endpoint (and now mass_create) return 400 with an error message whenever an error is encountered during the task creation. Previously, Trogdor would create the task as "DONE" and return a successful status code, making users manually inspect the tasks' status.
   This, unfortunately, has the nasty downside of returning 400 when an unexpected internal server error occurs. 
   I think that we can live with this for now and open up another KIP that could address error handling in the Trogdor Coordinator REST API.

> Trogdor supports the creation of tasks via the `coordinator/tasks/create` endpoint - it currently accepts only one task.
> Since Trogdor support scheduling multiple jobs to execute at a certain time (via the `startTime` task parameter leveraged by all tasks), it makes sense to support creating multiple tasks in a single endpoint. 
> Users might want to leverage the scheduler to, say, create 100 tasks. In the current model, they would need to issue 100 requests - which is inefficient.
