Ask HN: What would you consider “too short” and “too long” to stay at a job?

So I recently moved to the Bay area and started a position about ten months ago in the area of data science and ML. It's all right, but was always meant to be a stepping stone to something bigger, better, and more aligned with my intellectual interests. In recent weeks, I'm finding those roles and have started getting offers for in person interviews in other parts of the country. Given this back store, I was wondering what many of you thought about what is "too short" and "too long" to stay at a position.
