Upgrading Uber's MySQL Fleet

It's sort of funny how can you immediately tell it's LLM sanitized/rewritten.

It reads like any of those tech blogs, using big words where not strictly necessary but also not wrong

Don't know about your LLM feeling

It contains the word "delve", a word that got way more popular in use since the introduction of LLMs.

Also this paragraph sounds a lot like it has been written by LLMs, it's over-expressive:

    We systematically advanced through each tier, commencing from tier 5 and descending to tier 0. At every tier, we organized the clusters into manageable batches, ensuring a systematic and controlled transition process. Before embarking on each stage of the version upgrade, we actively involved the on-call teams responsible for each cluster, fostering collaboration and ensuring comprehensive oversight.

The paragraph uses "commencing from" together with "descending to". People would probably write something like "starting with". It shows how the LLM has no spatial understanding: tier 0 is not below or above tier 5, especially as the text has not introduced any such spatial ordering previously. And it gets worse: there is no prior mention of the word "tier" in the blog post. The earlier text speaks of stages, and lists 5 steps (without giving them any name, but the standard term is more like "step" instead of "tier").

There is more signs like "embark", or that specific use of "fostering collaboration" which goes beyond corporate-speak, it also sounds a lot like what an LLM would say. Apparently "safeguard" is also a word LLMs write very often.
