CONSISTENCY

Summary from the TLDR Web Dev newsletter

The concept of linearizability involves translating potentially overlapping histories of operations into equivalent sequential behaviors. This is an important concept to understand when implementing queue data structures. Achieving linearizability in a distributed queue is difficult as it’s challenging to achieve consistency without trading off availability and partition tolerance. This post explains various consistency properties, including monotonic reads, read-your-writes, writes follow reads, monotonic writes, and the consistent prefix. These properties allow developers to understand how to reason about correctness in distributed systems.
