YjsBased on our record, Apache Cassandra should be more popular than Yjs. It has been mentiond 44 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Of course, you don’t have to code this functionality from scratch! You can also look at open-source software like Yjs, text-crdt, Automerge and so many more. Alternatively, you can check out tools like Liveblocks, Ably, etc. Which enable collaborative multi-player features. - Source: dev.to / 4 months ago
I've built this app some time ago but only shared with close friends. It has been useful for me so I decided to share here. It works by sharing state with yjs [1], as long as you are in the same session, i.e. The same path. https://github.com/yjs/yjs. - Source: Hacker News / 7 months ago
I write undo/redo/history in web/JS extensively. This the best lib out there for such tasks IMHO: https://github.com/yjs/yjs And you're right. You don't want undo/redo only in multi-user apps. You want to have each user have their own local undo/redo events that they can apply and unapply from the shared state which has its own events apart from each user. Everyone... - Source: Hacker News / 9 months ago
After reviewing the ~600 lines of code, I have to ask what about this undo/redo manager is "advanced"? This seems like a naive implementation of a snapshot collection that is selected via array index. It's not event sourcing, OT or CRDT. With every event, the entire object is serialized and put into the heap. I can't even imagine what this does for performance when you deal with any object of significant size.... - Source: Hacker News / 9 months ago
I've seen it come up often in collaborative text editors. Also see: https://github.com/yjs/yjs. - Source: Hacker News / over 1 year ago
In fact, even in the absence of these commercial databases, users can effortlessly install PostgreSQL and leverage its built-in pgvector functionality for vector search. PostgreSQL stands as the benchmark in the realm of open-source databases, offering comprehensive support across various domains of database management. It excels in transaction processing (e.g., CockroachDB), online analytics (e.g., DuckDB),... - Source: dev.to / 19 days ago
All messages are persisted durably for two minutes, but Pub/Sub channels can be configured to persist messages for longer periods of time using the persisted messages feature. Persisted messages are additionally written to Cassandra. Multiple copies of the message are stored in a quorum of globally-distributed Cassandra nodes. - Source: dev.to / 6 months ago
Cassandra is a highly scalable, distributed NoSQL database designed to handle large amounts of data across many commodity servers without a single point of failure. - Source: dev.to / 11 months ago
Distributed storage Distributed storage systems like Cassandra, DynamoDB, and Voldemort also use consistent hashing. In these systems, data is partitioned across many servers. Consistent hashing is used to map data to the servers that store the data. When new servers are added or removed, consistent hashing minimizes the amount of data that needs to be remapped to different servers. - Source: dev.to / about 1 year ago
On the other hand, NoSQL databases are non-relational databases. They store data in flexible, JSON-like documents, key-value pairs, or wide-column stores. Examples include MongoDB, Couchbase, and Cassandra. - Source: dev.to / about 1 year ago
RxDB - A fast, offline-first, reactive Database for JavaScript Applications
Redis - Redis is an open source in-memory data structure project implementing a distributed, in-memory key-value database with optional durability.
Automerge - A JSON-like data structure (a CRDT) that can be modified concurrently by different users, and merged again automatically.
MongoDB - MongoDB (from "humongous") is a scalable, high-performance NoSQL database.
ShareDB - Realtime database backend based on Operational Transformation (OT)
ArangoDB - A distributed open-source database with a flexible data model for documents, graphs, and key-values.
