getForUpdateTs

public long getForUpdateTs()

 Each locking command in a pessimistic transaction has its own timestamp oracle.
 If locking fails, then the corresponding SQL statement can be retried with a later timestamp oracle, Executor does
 not need to retry the whole transaction. The name comes from the `SELECT ... FOR UPDATE` SQL statement which is a
 locking read. Each `SELECT ... FOR UPDATE` in a transaction will be assigned its own timestamp oracle.
