VSS Phase-II Tracking issue

[G8XSU]

Phase-II:
Overall: Phase-II covers multi-device parallel usage, where a 2+ devices use the same lightning state machine and vss as primary storage for critical data.
Ensuring sync b/w devices when one of them writes an update. Ensuring data-integrating by preventing lightning state from getting corrupted using key-level & global-level versioning.

VSS-Client Side :

• PrimarySecondary KVStore Implementation
• Sync client-side acc. to server side changes and ListKeysSummary
• Client-side impl for atomic multi-value filesystem-based store (possible required in SQLite if sled doesn't work for us)
• LDK-Node integration for error handling on write failure and re-sync local view storage and retry.
• LDK Integration with additional error type on write. (has some unknowns)

VSS-Server Side :

• Multi-tenanncy support - Create api to create storeId

Hi, any chance for an update on this issue? Thanks!

Hi,
Are you interested in phase-2 i.e. multi-device support or Vss phase-1 support that i.e. backups and using it as part of ldk-node?

[EthanYuan]

Yes, it is definitely worth learning from. vss-rs has also drawn from the VSS implementation. I understand that currently ldk-node has integrated the vss-client, but it hasn't fully utilized the version functionality yet (using -1). I'll keep an eye on future developments.
