Streaming Analytics
CrateDB turns vast volumes of streaming data into real-time insights. With its scalable ingestion engine and automatic indexing, CrateDB enables sub-second analytics, allowing businesses to monitor, analyze, and act on streaming data instantly, resulting in early anomaly detection, higher operational efficiency, and lower costs.
When Data Outgrows Your Database
Modern businesses generate and stream massive amounts of real-time data, from connected devices, sensors, machines, vehicles, applications, and infrastructure logs. Traditional databases and warehouses struggle to keep up with this continuous inflow of events:
- Time lag: Data must often be pre-aggregated or batch-processed, delaying insights.
- Scale limits: Billions of events overwhelm OLTP databases like Postgres or MongoDB.
- High cost: Running high-volume queries at scale on warehouses (Snowflake, BigQuery) becomes prohibitively expensive. Moreover, they’re not built for true real-time analytics in the sense of continuous, low-latency ingestion and instant querying on fresh data streams.
As a result, organizations can’t detect anomalies fast enough, miss opportunities to optimize operations, and struggle to feed real-time dashboards or AI models.

Turning Streaming Data Into Insights
CrateDB is designed to handle massive streaming workloads and deliver real-time insights at scale:
-
High-volume ingestion: Process data from Kafka, MQTT, CDC streams, and logs with ease.
-
Sub-second queries: Analyze billions of rows instantly, no pre-aggregation required.
-
Multi-model support: Time-series, relational, JSON, geospatial, text, and vector data all in one database.
-
Live data enrichment: Combine streaming data with other sources on the fly.
-
SQL-native & PostgreSQL wire protocol compatible: Integrate seamlessly with BI tools and applications.
-
Effortless scalability: Grow horizontally on commodity hardware or in the cloud.
-
Flexible schema: Adapt your data model as new data arrives.
-
Automatic indexing: Store complex objects before knowing how you’ll query them.

From Insights to Impact
Turn streaming data into real-time action with CrateDB:
-
See it instantly: Monitor equipment, fleets, grids, or user activity as it happens.
-
Act proactively: Spot anomalies and trigger alerts immediately.
-
Cut costs: Replace multiple specialized systems with one unified platform.
-
Future-proof your data: Feed AI models directly, no complex ETL needed.

FAQ
Streaming analytics refers to real-time processing and analysis of data as it flows in (e.g. from sensors, logs, events). It allows organizations to detect anomalies, trigger actions, and make decisions immediately, rather than relying on batch processing that introduces latency.
CrateDB is engineered for scalable ingestion from sources such as Kafka, MQTT, CDC streams, and logs. It features automatic indexing and distributed architecture that let it scale horizontally and sustain large throughput while serving sub-second queries.
Yes, CrateDB supports native SQL. You can query streaming and time-series data using familiar SQL semantics (aggregations, windowing, joins) without needing to learn a proprietary query language.
CrateDB supports flexible schemas, allowing you to ingest semi-structured data (e.g. JSON fields) and evolve your schema over time. This makes it easier to adapt as new sources and fields emerge.
It’s particularly effective in scenarios such as IoT (sensor monitoring), log and event analytics, anomaly detection, fleet/transport monitoring, real-time dashboards, AI/ML feature pipelines, and any system requiring near-instant insight from high-volume continuous data.
IoT data is stored in databases designed to handle large-scale, real-time data. Smart partitioning strategies are key to manage multiple periods of time efficiently. Depending on the specific application and requirements, these databases can be on-premises, cloud-based, or edge-based. CrateDB is highly flexible and can be deployed on private or public cloud, on-premises, or edge to meet your organization's unique needs. It also supports hybrid scenarios out of the box.
An IoT database architecture typically includes several key components: IoT devices that generate data, a network for transmitting this data, a storage system for data accumulation, and an analytics component for data processing. The architecture is designed to manage data flow from devices to storage and ultimately to analysis platforms, ensuring timely and accurate insights. CrateDB addresses these needs by providing easy and seamless integration with popular IoT stack software such as Kafka, Grafana, and Node-RED, leveraging native SQL and the PostgreSQL Wire Protocol.
