Optimizing Odoo 17 ERP Sync: Architectural Blueprint for 30-Second Heartbeats

Connecting 10,000+ mobile field devices directly to an Odoo PostgreSQL database requires micro-batch payload management and resilient offline queues to prevent database locking or server throttling.

1. Micro-Batch REST API Payload Compression Rather than sending raw individual HTTP requests for every check-in, Smart Worker App groups local device events into JSON micro-batches sent over 30-second keep-alive heartbeats.

2. Double-Tick Verification Ledger Every synced record receives a double-tick confirmation code between the mobile local SQLite database and Odoo HRMS ledger, ensuring 100% data integrity without duplicate entries.

3. Offline Caching & Failover Strategy When cellular connectivity drops at remote sites, local device caches store up to 5,000 logs and auto-sync immediately upon network restoration.
