The article explores the use of Couchbase as a storage solution for machine learning models, emphasizing its suitability for online machine learning where models are frequently updated and predictions are served in real-time. Couchbase's memory-first architecture facilitates high throughput and low latency, enabling efficient storage and retrieval of models in either binary or JSON format. While binary storage minimizes size and conversion needs, JSON allows for greater transparency and querying capabilities. The text also discusses the use of Open Neural Network Exchange (ONNX) for model interoperability across different frameworks and details the processes of training, serializing, and deploying models using Couchbase. The article highlights Couchbase's ability to meet requirements such as high availability, scalability, secure data access, and ease of management, ultimately reducing complexity and operational overhead by consolidating multiple data store functions into a single platform.
