    Description

      In one MDT system recovery, the transactions are replayed in transaction order, but in DNE system recovery, the transactions are replayed on all MDTs in parallel, currently if two transactions have dependency, and the latter transaction is a distributed transaction, the dependency is eliminated by commit-on-sharing, however if these two transactions are started by the same MDT, they are replayed by transaction order, therefore commit-on-sharing is not needed here.
