Analytical Offload
Where Analytics Go Wrong
Many organizations still run analytics directly on operational databases like Postgres or MongoDB. The result is:
- Slow queries: Analytical workloads interfere with OLTP performance.
- High costs: Scaling OLTP systems for analytics is inefficient and expensive.
- Complex ETL pipelines: Moving data into warehouses or separate engines adds latency and overhead.

How CrateDB Fixes It
CrateDB enables organizations to separate analytics from operations while keeping everything in sync:
- Seamless replication: Change Data Capture (CDC) pipelines sync CrateDB with Postgres or MongoDB.
- Real-time analytics: Run ad-hoc queries, dashboards, and AI workloads directly in CrateDB.
- SQL-native: Works instantly with BI tools and applications.
- Elastic scale: Handle billions of rows and high concurrency with cost-efficient horizontal scaling.

The Results You Get
- Faster insights: Queries run milliseconds, not minutes or hours.
- Lower TCO: Eliminate costly OLTP scaling and reduce analytics infrastructure spend.
- Operational stability: Keep transactional systems responsive by offloading analytics.
- Simpler architecture: Remove complex ETL pipelines and multiple database dependencies.

How CrateDB relates to your data warehouse
-
Data warehouses for batch analytics, reporting, and ML training.
-
CrateDB for real-time dashboards, metrics, and alerts.
-
Cost savings and better performance by focusing the warehouse on heavy batch jobs and CrateDB on sub-second queries on fresh data to reduce warehouse query load.
-
Hybrid architecture: CrateDB for real time, the warehouse for long-term and historical analysis.

FAQ
Analytical offload involves transferring resource-intensive analytical workloads from operational databases (like PostgreSQL or MongoDB) to a specialized system. This separation ensures that transactional systems remain responsive, while analytics can be performed efficiently and at scale.
CrateDB enables seamless replication from operational databases using Change Data Capture (CDC). This allows for real-time analytics on fresh data, supporting ad-hoc queries, dashboards, and AI workloads without impacting the performance of operational systems.
Yes. CrateDB can complement data warehouses by handling real-time analytics, while the warehouse focuses on batch processing and long-term storage. This hybrid approach optimizes performance and reduces costs.
Key benefits include:
- Faster insights: Millisecond query responses.
- Cost savings: Reduced need for scaling operational databases.
- Operational stability: Uninterrupted performance of transactional systems.
- Simplified architecture: Elimination of complex ETL processes.
CrateDB excels in scenarios requiring real-time analytics, high ingestion rates, and support for both structured, semi-structured and unstructured data. It's ideal for applications like IoT monitoring, log analysis, and real-time dashboards.
