OLTP DBMSs in enterprise scenarios are often facing the challenge to deal with workload peaks resulting from events such as Cyber Monday or Black Friday. The traditional solution to prevent running out of resources and thus coping with such workload peaks is to use a significant over-provisioning of the underlying infrastructure. Another direction to cope with such peak scenarios is to apply resource sharing. In a recent work, we showed that merging read statements in OLTP scenarios offers the opportunity to maintain low latency for systems under heavy load without over-provisioning.
