Real-Time Ingestion

CrateDB is designed to handle today’s relentless data velocity. Whether it’s IoT telemetry, application logs, or sensor networks, CrateDB ingests millions of events per second with horizontal scalability. Its shared-nothing architecture ensures performance grows linearly with your cluster; no bottlenecks, no single point of failure.

CrateDB connects effortlessly to your data pipelines through native integrations and open interfaces. Ingest data from Kafka, Flink, MQTT, HTTP APIs, or CDC pipelines, and keep your analytics continuously up to date. Combine structured, semi-structured, and unstructured data in a single real-time pipeline, without complex ETL.

CrateDB ingests and indexes data in parallel across all cluster nodes, making every event queryable within seconds. Its built-in sharding and replication ensure resilience and instant availability, so dashboards update in real time, alerts trigger immediately, and AI models always use the freshest data.

Data in CrateDB becomes useful the moment it arrives. The ingestion engine automatically indexes every record for search, aggregation, and vector operations, with no manual tuning required. Run real-time analytics or feed live features into AI models just seconds after ingestion.

CrateDB brings ingestion, indexing, and querying together in one unified database. No separate systems to maintain or sync.
