Store Service Upgrade

Waku Roadmap Entry

GitHub Milestone

Deliverables

  1. ✅ Store v3-beta - Message Hashes: F1, U2
  2. ❌ Store v3 - store synchronisation F2, R3, P1
  3. ✅ DoS protection for req-res protocols and metrics F3, R2. P4 (nwaku)
  4. ✅ PostgreSQL Maintenance: F4, U1. R1, P2, P3 (nwaku)
  5. ✅ Metric: Count store messages F5

Functionality

  1. ✅ Messages can be retrieved from store nodes using their hashes

  2. ❌ Store nodes can synchronise their latest messages with each other

    Used an off-the-shelf protocol and library but the performance and API for Waku use case was inadequate (eg, removing messaging from sync window). Decided to design new protocol, more optimized (different fingerprint and storage strategies) and future proof. eg, will be possible to use content topics as sync criteria. Will be defined in new FURPS/Milestone.

  3. ✅ Service nodes are DoS protected using request rate limitation

  4. ✅ PostgreSQL database growth is capped and pruning automated

  5. ✅ A tool to compare the messages across fleet nodes is deployed

Usability

  1. ✅ Node operators are able to hard cap disk space used on local store nodes: ✅
  2. ✅ Reliability protocols and Waku Sync can use message hash queries ✅
