• Priority: Minor

• Severity: 3
• Assignee: Lai Siyao

Description

DNE system doesn't need to support REP-ACK, because similar to the original Commit-on-Sharing, EX|PW mode locks are downgraded to TXN mode, and kept in reply_state till transaction commit, which can guarantee transaction dependency.
