WebApr 7, 2024 · This is the first work to characterize the complexity of consistency checking for C11 memory models, in particular, the RC20 model, its release-acquire fragment, the strong and weak variants of RA (SRA and WRA), as well as the Relaxed fragment of RC20. Over the years, several memory models have been proposed to capture the subtle … WebApr 20, 2024 · If consistency is what you prefer, then you should go with a homogenous architecture. In this case, system attributes such as physical resources, operating system, and DBMS are uniform across all the sites. With homogenous architectures, deployment and management of database sites become easier.
