Monolithic Ledger Sync Grid

Multi-Tenant Database Architecture & Collision Prevention
⚡ Key Performance Metric: 140+ Nodes | 0.4ms Write Sync
PostgreSQL Golang Redis Distributed Locks

The Challenge

Concurrent high-frequency ledger postings caused database deadlock locks and slow reconciliation cycles during market closing hours.

The Technical Solution

Designed an isolated partition sharding model with row-level locking optimizations and transactional idempotency keys.

Architecture & Stack Specifications

PostgreSQL Partitioning, Redis Locks, Golang Worker daemons, Docker

Measured Results & Impact

0.4ms median ledger write sync time; zero deadlock lockups across 140+ tenant nodes.
