Hi Question on segments. Is there a way to uniquely identify a segment? Looking through a bunch of classes/interfaces in pinot-segment-spi. Don’t see anything. Hopefully just missing it. Looking at the tests (ConcurrentMapPartitionUpsertMetadataManagerTest for example) I can see segments being replaced by segments with the same name. So the segment’s name does not identify it uniquely. Is there anything that would uniquely identify a segment? And be stable? So I could refer to a segment through a property(s), not just the pointer to the segment implementation instance.

Could you elaborate on why you need to store a pointer to segment?
