Could you share multiple scenarios using several tasks providing the YAML flow, the execution result (Gantt chart, logs) please?

OK looks great @thearpankumar thanks!

Also, did you check the outputs are as expected?

By the way, did you know you can use pluginDefaults (see the doc) for common properties inside a given package?

thearpankumar · 2025-10-02T08:41:24Z

OK looks great @thearpankumar thanks!

I have checked the output too, it is as expected by me if you don't like something just mention then i will try to fix it. also I mean ya i could have used pluginDefaults, but they are test creds so i didn't bother about that next time surely i will.

fdelbrayelle · 2025-10-02T09:35:13Z

Yes it was just for you to know about the pluginDefaults feature ;-)

thearpankumar · 2025-10-02T10:42:28Z

@fdelbrayelle thank you 😊. if every thing is ok now please merge the PR

fdelbrayelle · 2025-10-02T10:48:01Z

Let's wait for @Malaydewangan09's last review tomorrow 🙏

thearpankumar · 2025-10-02T12:08:25Z

@fdelbrayelle can you please label this issue as hacktoberfest or hacktoberfest-accepted ?? will then this PR will also be counted as one

fdelbrayelle · 2025-10-02T12:44:40Z

@thearpankumar I added the hacktoberfest at the repository level so it should be good now.

- Extract common properties to AbstractDocumentDBTask base class - Replace manual Ion serialization with FileSerde.writeAll() and Flux streaming - Convert ReadTest to use real database instead of asserting connection failures
