What does this sentence mean?
This mode primarily applies to transactions with {@code SERIALIZABLE} isolation.
That it has no effect on RR? Or that it has a strong effect on Serializable?
What I'm aiming at is: Can we make this more concrete? As a customer, I would have no idea what this means.

I've updated the doc. Currently, we do not allow setting the readLockMode for Repeatable Read(RR) isolation level and error will be returned. And by default, OPTIMISTIC lock mode will be used for RR.
