Pitfalls of isolation levels in distributed databases

The more loosely coupled components are in a distributed system, the better it scales. This rule applies to distributed databases, too, and the isolation level plays a big part in this. This post attempts to explain what these isolation levels mean and the tradeoffs between them. We also give you recommendations on how to choose the isolation level best suited to your needs. There exists a set of ANSI Standards for isolation. There is also a critique about those standards explaining the ambiguit

MySQL semi-sync replication: durability consistency and split brains

MySQL semi-sync is a plugin mechanism on top of asynchronous replication, that can offer better durability and even consistency (term defined later). It helps in high availability solutions, but can in itself reduce availability. We look at some basics and follow up to present scenarios that require higher level intervention to ensure availability and to avoid split brains from taking place. I recommend reading this semi-sync blog post by Jean-François Gagné (aka JFG), which illustrates the inte
