srkukarni opened a new pull request #4223: Make Function submission checks optional URL: https://github.com/apache/pulsar/pull/4223 ### Motivation Currently when users submit functions/source/sinks, the function worker does some pretty extensive checks for java functions. This checks involve loading the user defined classes. Since function-worker is privileged code, but function itself is non-privileged, it could lead to situations where a misconfigured/malignant user-code causes catastrophic cluster failures. This pr adds a switch to make these checks optional. ### Modifications *Describe the modifications you've done.* ### Verifying this change - [ ] Make sure that the change passes the CI checks. *(Please pick either of the following options)* This change is a trivial rework / code cleanup without any test coverage. *(or)* This change is already covered by existing tests, such as *(please describe tests)*. *(or)* This change added tests and can be verified as follows: *(example:)* - *Added integration tests for end-to-end deployment with large payloads (10MB)* - *Extended integration test for recovery after broker failure* ### Does this pull request potentially affect one of the following parts: *If `yes` was chosen, please highlight the changes* - Dependencies (does it add or upgrade a dependency): (yes / no) - The public API: (yes / no) - The schema: (yes / no / don't know) - The default values of configurations: (yes / no) - The wire protocol: (yes / no) - The rest endpoints: (yes / no) - The admin cli options: (yes / no) - Anything that affects deployment: (yes / no / don't know) ### Documentation - Does this pull request introduce a new feature?
