“Key-Value” is Misleading. Access Patterns are Key.

This post elaborates on the importance of access patterns in database selection and data modeling, contrasting different data models (Key-Value, Wide-Column) and their implications for performance, I/O costs, and infrastructure spend. It highlights how ScyllaDB's architecture can accommodate various levels of access pattern depth, from simple key-value stores to more complex wide-column structures, and emphasizes that understanding application read/write behavior is crucial for optimal performance and cost-efficiency.
