However, this approach quickly becomes cumbersome when dealing with rapidly changing data, such as sensor readings from IoT devices.
Traditional databases need to be optimized to handle complex event processing.
2. Streaming Databases
Streaming databases utilize a continuous data stream for real-time analysis.
Such databases ingest and process data in real-time, allowing for immediate analysis and action.
Rather than waiting for a query to be executed, streaming databases continuously analyze the data as it comes in, allowing for real-time decision-making.
Streaming databases excel at handling and analyzing complex event-processing data. This means that streaming databases are better suited for use cases such as fraud detection, anomaly detection, and real-time monitoring.
While traditional databases have their strengths, there are better solutions for real-time data analysis. Streaming databases offer a more efficient approach to rapidly changing data and enabling real-time decision-making.
