Need Better Sync Implementation Guidance for SmartStore/MobileSync

[abhinavRepo26]

I'm struggling to implement proper incremental sync and deleted record cleanup with SmartStore/MobileSync. My current sync strategy is inefficient and I need guidance on the correct implementation approach.

Current Setup:

React Native with Salesforce SDK v13.1.0
Using SmartStore and MobileSync
Two sync modes: Transactional Sync & Master Sync

Current Implementation Problems:

Transactional Sync:

1. Push local transactional data to server
2. SyncDown only transactional soups
3. Missing incremental sync capabilities
   4.Not handling server-side deletions

Master Sync:

1. Push all transactional data
2. Reset SmartStore completely
3. SyncDown all soups from scratch
4. Very inefficient for large datasets

What I Need Help With:

1. Incremental Sync Implementation:
2. How to properly implement delta sync (only changed records)
3. How to handle server-side deletions in client
4. Proper use of lastModifiedDate and sync targets
5. Sync Order & Best Practices:
6. Correct sequence for push/pull operations
7. How to handle conflicts
8. When to use clean sync vs incremental sync
9. SmartStore Optimization:
10. How to avoid complete store resets
11. Proper soup configuration for efficient sync

Specific Questions:

1. What is the proper way to implement incremental sync that only downloads changed records?
2. How do I detect and handle records deleted on the server?
3. What's the recommended sync strategy for mixed transactional/master data?
4. How to configure sync targets for automatic delta detection?
5. Best practices for conflict resolution during sync?

Expected Outcome:

1. Efficient incremental sync implementation
2. Proper handling of server-side deletions
3. Optimized sync performance
   4.Reduced data transfer
