mongodb oplog meaning
4
QUESTION
4
I've seen this question posed before, but the answers were very vague. I have been doing some research on oplog, and am trying to understand exactly how it works. In particular, I want to have a good understanding of the fields in an oplog document and what data they store.
These are the fields I have found through tests and what I think they mean as well as what I am still unsure of:
ts: timestamp of the write operation / oplog entry
h: a unique identifier for the oplog entry (but why is it sometimes positive and sometimes negative?)
