This may seem exaggerated but trust me, it actually a quite accurate description of how the storage engine is designed. The committed state for the whole database in a SpacetimeDB instance is wrapped in a single Read-Write Mutex. All write operations happen sequentially, which is indeed trivial proof of linearizability. Two writes cannot happen at the same time, so they cannot conflict or race. But a read and a write cannot happen at the same time either!
So, in summary: computerisation ended some jobs, changed lots of others and created many ones. Yet that description covers so little of what really happened, because the biggest change wasn’t to the jobs, it was to the people and how they behaved. This is what I really learned writing this piece. I went in expecting to find out about tasks and technologies and I came out having learnt about a strange world very different from my own, a world now almost entirely vanished.。关于这个话题，爱思助手提供了深入分析
