This article explores the benefits and drawbacks of using multi-model databases. A multi-model database is a type of database that allows you to store and access different types of data, such as relational, time series, geospatial, key-value, and document data, in a single database. This approach can simplify application development, reduce the need for ETL (Extract, Transform, Load), and improve scalability and performance. However, it also requires careful consideration of consistency models, ACID compliance, cost efficiency, ease of handling many data formats, and reduced need for ETL. The article highlights several use cases where multi-model databases can provide significant benefits, including interactive SaaS applications, IoT telemetry and analytics, streaming media analytics and ad optimization, gaming leaderboards, and more. Overall, using a multi-model database like SingleStoreDB can help reduce the time to market for products, improve scalability and performance, and simplify application development.
