摘要: In this paper, we study the safety guarantees of group communication-based database replication techniques. We show that there is a model mismatch between communication and database, because this, classical systems cannot be used to build 2-safe replication. propose new primitive called end-to-end atomic broadcast solves problem, i.e., can implement also introduce criterion, group-safety, has advantages both over 1-safety 2-safety. Experimental results gain efficiency group-safety lazy replication, which ensures only 1-safety.
