The following issues are known to affect usability:
Stability and Security
The DXOS platform and SDK is currently in a technology preview state.
- Persistence, integrity, or confidentiality of user data is not guaranteed.
- Protocols, libraries, and SDKs are likely to change, so DXOS SDK components should not yet be used for production.
- Security of the platform and SDK is immature and incomplete. Identity and device authentication is verified using strong encryption. Data is encrypted in transit. Data stored locally, in-browser, in OPFS or IndexedDB may not be encrypted.
Performance, Reliability, and Scale: Current state
On startup, all mutations must be loaded before the space is available to use.
Browser: 35k mutations/sec
Agent: 50k mutations/sec
Under normal conditions, a space will have 5,000 or less mutations, so cold startup time will be less than a second.
Changes to a space need to be replicated to peers. When sharing a space to a new peer, or when a peer comes back online, it must receive all mutations.
Browser: 800 mutations/sec
Agent: 1300 mutations/sec
1 MB/s throughput.
Under normal conditions, full replication will take 10 seconds or less.
Reliability and Scalability
Our communications protocol currently establishes a separate mesh of connections per shared space. A Mostly Minimal Spanning Tree is used to minimize the connections per node. For example, two users sharing three spaces will result in three connections, but four users sharing one space will create slightly more than the minimum of three connections.
With a nominal amount of continuous activity (400 mutations/sec), our communications protocol can handle a maxmimum of 40 total connections.
