I am a student, and learning RCU now, but still know very little about it.
Are there any documents/papers/materials which (in)formally define and
explain RCU consistency guarantees?
I know there are some consistency models in the database area (such as
PRAM, Read Uncommitted, etc) from https://jepsen.io/consistency and .
How does RCU related to those consistency models?
I also found some comments online (One key distinction is that both MVCC
and RLU provide much stronger consistency guarantees to readers than does
RCU ...) (https://lwn.net/Articles/777036/).
I do not understand how we reason/dresibe/compare the
consistency guarantees. ( I even do not know what consistency guarantees
provided by RCU formally)
Could someone explain this to me?
