and versioned operation sync.
Highlights
Added collaborative document APIs for create, sync, delta changes, and presence.
Implemented conflict-free merge logic for concurrent text edits, field updates, and spreadsheet cell updates.
Added Socket.IO live collaboration events for join, operation broadcast, acknowledgements, and presence.
Enabled offline editing support via operation replay and since-version incremental sync.
Added Redis-based cross-instance event fan-out for low-latency horizontal scalability.
Outcome
Delivers consistent multi-user editing across devices and sessions with deterministic conflict handling, fast realtime updates, and robust offline-to-online synchronization.
