Edge databases run close to data sources (sensors, machines, vehicles) to enable low-latency processing without cloud round-trips. Unlike traditional centralized databases, they handle high-speed ingestion, real-time analytics, offline operation, and lightweight deployment. Modern architectures use a three-tier pattern: edge tier for local intelligence, cloud tier for aggregation and training, and enterprise tier for business applications. Edge databases reduce bandwidth costs by pre-processing data locally, maintain reliability during network outages, and support distributed AI/ML pipelines. CrateDB provides these capabilities through high-speed ingestion, SQL analytics, vector search, autonomous operation, and selective cloud synchronization.
