René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Python functions shut down slowly","articleBody":"### What happened?\r\n\r\nI'm not fully sure where to report this, but the point is that after introducing a composition function developed with python, we noticed that:\r\n- The latency of the function deployment to do a rollout restart is way larger than others (e.g. based on go sdk)\r\n- The amount of time it takes for `crossplane render` got penalized as well.\r\n\r\nThis is negatively impacting both CI and DevEx since rendering a composition is quite a common use case.\r\n\r\n### How can we reproduce it?\r\n\r\nI just tested this with a dummy function which does nothing:\r\n\r\n```python\r\n    async def RunFunction(\r\n        self, req: fnv1.RunFunctionRequest, _: grpc.aio.ServicerContext\r\n    ) -\u003e fnv1.RunFunctionResponse:\r\n        \"\"\"Run the function.\"\"\"\r\n        log = self.log.bind(tag=req.meta.tag)\r\n        log.info(\"Running function and doing nothing\")\r\n\r\n        return response.to(req)\r\n```\r\n\r\nRunning `crossplane render` on a composition that has this function as a dependency (not necessarily used in the pipeline, just declaring this as a dependency in `crossplane.yaml` is enough) adds an extra ~10s. A couple of experiments with simple compositions raise the amount of time for the render command from 1-2 seconds to 10-12 seconds.\r\n\r\nI was suspecting that [this](https://github.com/crossplane/function-sdk-python/blob/main/crossplane/function/runtime.py#L119) could have something to do, and played by setting it to `None` but apparently didn't help :(\r\n\r\n### What environment did it happen in?\r\nfunction-sdk-python version: 0.5.0\r\ncrank version v1.18.0\r\n\r\n","author":{"url":"https://github.com/fernandezcuesta","@type":"Person","name":"fernandezcuesta"},"datePublished":"2024-11-15T13:02:38.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/109/function-sdk-python/issues/109"}
