Column Store
A column store database stores data column-by-column, optimizing for analytical workloads (OLAP) and scanning specific fields across many rows.
Telemetry, analytics, and evaluation logs for AI systems often live in column stores—key for FinOps and quality dashboards.
Explanation
It compresses well and is fast for aggregations; writes can be slower and updates more complex than row stores.
Marketing Relevance
Telemetry, analytics, and evaluation logs for AI systems often live in column stores—key for FinOps and quality dashboards.
Example
Aggregating "cost per verified answer" across millions of events.
Common Pitfalls
Using column stores for high-write OLTP workloads; schema drift without governance; expensive joins without modeling.
