Hihooi implements the \textit{lazy fined-grained} approach, through transet propagation via the Memcache server.  Hihooi's design, proves to be flexible enough and allows clients to choose between the available transaction isolation levels provided by the underlying databases by setting the SET\_TRANSACTION SET-TRANSACTION  parameter before each START\_TRANSACTION START-TRANSACTION  request. In the context of \cite{Cecchet_2008} Hihooi uses a master-slave replication protocol, query interception in JDBC-based replication, query-level load balancing, and statement replication.  More recent research in database replication includes Megastore \cite{megastore} , Calvin \cite{Thomson_2012}, and Spanner,Google's Globally-Distributed Database  \cite{Corbett_2013}. Although these works focus on partitioned databases, we mentioned them briefly for completeness.
