@RunLLM Is there a difference between a backlog and a local backlog?

It seems likely that "backlog" in Pulsar and StreamNative refers to the set of unacknowledged messages for a topic or subscription, while "local backlog" is not a standard term in the official documentation or APIs. The term "local backlog" may appear in some monitoring charts or UI contexts, but it is not explicitly defined in the main data sources. The general "backlog" is well-defined as unacknowledged messages stored by bookies until processed and acknowledged by consumers, and is subject to backlog quotas and policies according to StreamNative documentation. If you are seeing "local backlog" in a specific UI or chart, it may refer to the backlog as seen from a particular broker or node, but this is not explicitly documented in the official sources. Would you like more detail or clarification on a specific context where you see "local backlog"?
