CRDT Paper

Yjs is a CRDT implementation. It implements an adaptation of the YATA CRDT with improved runtime performance.

Implementation Details

Choosing efficient data structures is critical when implementing a CRDT. The following document gives an overview of the data structures used in Yjs.

Optimizations Overview

JavaScript manages memory automatically using a garbage collection approach. Yjs is a particularly efficient implementation of the YATA CRDT that works well in the browser and in NodeJS. This article analyzes the performance of Yjs in JavaScript.
