https://ar5iv.labs.arxiv.org/html/2301.08906v1 - "...We have extended the CAP theorem to relate quantitative measures of these two properties to quantitative measures of communication and computation latency (L), obtaining a relation called the CAL theorem that is linear in a max-plus algebra. This paper shows how to use the CAL theorem in various ways to help design real-time systems..."

While all those design strategies are indeed valid, and adaptable dynamic quorum sizes, have the potential to manage certain trade-offs, the practical implementation of such systems presents such a challenges, due to the inherent complexities of distributed systems that...Tackling these complexities with those strategies should be approached with a degree of humility. Overheads and latency issues in node replacement, particularly under conditions of unexpected high load or network difficulties, compound these challenges. These issues often manifest in correlated failures, which are more…
