Scaling Farcaster

  • Currently 80K daily users
  • How do we scale to 1M users
  • Goals
    • Hubs should be less than $1000 a month
    • Message delivery, arrive in 10 seconds 90% of the time
    • 99% of hubs are “in sync”, according to some health metric.
    • 99.9% of data can replicate to an external database in < 1s.
  • Sync
    • Improve Snapshot sync
    • Improve Gossip sync
    • Diff sync
  • State
    • Trying to move to SSD for broader commodity hardware, while also updating hub requirements

​
Shuttle

  • New replicator package
  • Less opinionated compared to the older replicator
  • Will give hub operators more flexibility with how they want to index and use the data

​
Frames

  • Cast Actions
    • Working on discoverability, like a discover page
    • Next up would be looking into actions opening frames. e.g. you click “tip $DEGEN” and a frame pops up with how much you want to send
    • Replace or delete actions is down the road
    • Looking at moving away from deep link urls and moving towards a metadata structure similar to frames

Warpcast Topics

​
App Performance and Quality

  • Direct Casts
    • Top Warpcast priority
    • Rewriting direct casts to work better at scale
    • Should have the same performance as other apps you use
    • Long term plans
      • once stable, will be looking into programatic read and writes for DCs
      • even longer term find ways to give access to DCs to other clients
  • Fixing crashes and general performance

​
Notifications

  • New area Warpcast team is looking to focus on
  • Give people control to different categories to fine grain, but make the default algorithmic similar to the home feed
