Multiple hosts can generate the same ID. I suggest switching to UUIDs (e.g., uuid.uuid4()) for guaranteed uniqueness. It’s my understanding that the *Spark* `monotonically_increasing_id()` function exists for the exact purpose of generating a collision-resistant unique id across nodes on different hosts. We use it extensively for this purpose and have never encountered an issue. Are we wrong or are you thinking of a different (not Spark) function?
