> This sounds like a great capability! I haven't read the implementation in detail yet, but I see that not many tests were added. Can you talk about what tests would be needed to safeguard us from regressions. Do we have the needed test infrastructure to write integration tests for these scenarios? If not, what's missing? Hi @suneet-s Thanks for response. This feather has an important property named `enableDynamicAllocationTasks` which is false as default value. If users set it false or ignore this property, this feather will be disable and have no impact on indexing service. All the ingest related UTs or ITs are passed which can ensure this conclusion. If anything goes wrong caused by this feather, we can solve it easily. Just set it false. The core design of this PR is to do a little change of supervisor behavior in overlord. Now overlord can build a `dynamicAllocationNotice` itself to change the task number. So that I just modify `SeekableStreamSupervisorStateTest` to test and prove that Supervisor works fine including start, stop and so on when setting `enableDynamicAllocationTasks` true and enable this feather. Also more test can be added if necessary and the existing architecture is sufficient to meet this requirement. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
