SLOG: serializable, low-latency, geo-replicated transactions Ren et al., The challenge with strict serializability (or even just serializability on a regular DBMS) is that it requires coordination, and as we know, coordination kills performance. That’s where SLOG (Serializable LOw-latency, Geo-replicated transactions) comes in.
