Guaranteed exactly-once semantics ensure stock counts are correct under concurrent high-volume order events
Multi-Channel
Source Joins
Join online orders, POS events, warehouse transfers, and supplier shipments in a single SQL inventory view

Why Real-Time

Why does inventory tracking need a streaming database?

Batch inventory jobs introduce minutes of lag between a sale and a stock update. During peak demand, that lag causes overselling, failed fulfillments, and customer complaints. A streaming database eliminates the batch window by maintaining inventory state as a continuously updated SQL view — every order event is reflected immediately.

InfrastructureETL + OLTP + RedisSingle SQL system
  • Eliminate overselling by reflecting order deductions within milliseconds of checkout
  • Detect reorder points as soon as stock falls below threshold — not at the next batch run
  • Join order events, returns, and warehouse transfers in SQL without custom aggregation logic
  • Scale inventory computation horizontally without redesigning application-level caching

Use Cases

Where does real-time inventory tracking matter most?

Any operation where stock accuracy directly impacts revenue or customer experience benefits from real-time inventory tracking. E-commerce, warehouse operations, retail, and supply chain teams all see measurable improvements in fulfillment accuracy and stockout prevention.

E-Commerce Stock Management

Track available-to-promise inventory across warehouses and fulfillment centers in real time, preventing overselling by reflecting order events within milliseconds of checkout

Warehouse and 3PL Operations

Aggregate inbound receipts, putaway, picks, and shipments continuously to maintain accurate bin-level inventory for warehouse management systems

Retail Point-of-Sale Sync

Ingest POS transaction events from Kafka and maintain real-time stock counts per store location, enabling instant cross-store inventory visibility and replenishment alerts

Supply Chain Visibility

Join supplier purchase orders, in-transit shipments, and warehouse receipts in SQL to track inventory across the full supply chain and predict stockout risk

How It Works

How does RisingWave power real-time inventory tracking?

RisingWave ingests order, fulfillment, return, and warehouse events from Kafka or directly from database CDC streams. SQL materialized views continuously aggregate net stock per SKU and location. Your ERP, OMS, or fulfillment system queries current inventory through a standard PostgreSQL connection.

  • Connect Kafka order topics and warehouse event streams using SQL CREATE SOURCE statements
  • Define net stock as a materialized view: SUM(inbound) - SUM(outbound) GROUP BY sku, location
  • Join stock levels against reorder thresholds to create a continuously evaluated alert view
  • Query current inventory from your ERP, OMS, or storefront via any PostgreSQL client
  • Use CDC sources to track inventory changes directly from your order management database
