Real-Time IoT Data Processing
That Scales to Millions of Sensors

RisingWave ingests high-volume sensor streams, detects anomalies in sub-second windows, and powers live dashboards — all with standard SQL and no Flink pipelines.

Sub-100ms
Anomaly detection latency

From sensor reading to alert in under 100 milliseconds

SQL
No custom code required

Define complex windows, joins, and aggregations in plain SQL

10M+
Events per second

Horizontally scale compute without scaling storage

S3-backed
Infinite retention

Store historical sensor data on S3 at object-storage cost

Why Traditional Architectures Fail IoT at Scale

IoT generates a firehose of time-series data. Most teams wire together Kafka, Spark Streaming or Flink, a time-series DB, and a separate alerting layer. Each hop adds latency, operational burden, and failure points.

Batch processing misses real-time events

Hourly or minute-level aggregations cannot detect a temperature spike or equipment failure the moment it happens.

Complex pipelines are brittle

Managing Flink jobs, schema registries, and stateful operators requires specialized expertise and breaks during upgrades.

Storage costs explode with raw retention

Storing every raw sensor reading in a traditional database or data warehouse becomes cost-prohibitive at scale.

Streaming Database vs. Traditional IoT Stack

RisingWave replaces the Kafka Consumer + Flink + Time-Series DB stack with a single SQL layer that handles ingestion, processing, and serving.

Frequently Asked Questions

What is the best architecture for real-time IoT data processing?

The best architecture ingests sensor data via Kafka or MQTT, processes it in a streaming database like RisingWave using SQL, and writes results to a dashboard or downstream sink. This replaces complex Flink/Spark pipelines with a single SQL layer.

How do you handle millions of IoT sensor readings per second?

Use a horizontally scalable streaming database that decouples compute from storage. RisingWave stores state on S3 and scales compute nodes independently, processing millions of events per second without data loss.

What is the difference between batch and streaming for IoT analytics?

Batch processing aggregates IoT data in periodic windows (minutes to hours), missing anomalies between runs. Streaming processes each reading as it arrives, enabling immediate anomaly detection, predictive maintenance, and real-time dashboards.

How do I detect anomalies in IoT sensor data in real time?

Define a materialized view in RisingWave that computes rolling averages over a sliding window. When a sensor reading deviates beyond a threshold, trigger an alert via a sink to Kafka, PagerDuty, or a webhook.

Does RisingWave support MQTT for IoT data ingestion?

Yes. For MQTT, route messages through an MQTT-to-Kafka bridge such as EMQX and ingest from Kafka into RisingWave. RisingWave natively supports Kafka, Redpanda, Pulsar, and Kinesis.
