OLAP databases are designed for analytical querying, with different capabilities and deployment choices to consider across workloads. Compared on data lake querying, real-time ingestion, and query concurrency, these entries also vary in materialized views and whether compute and storage are separate. Deployment model helps frame where a system can run, while free-plan availability and paid-from pricing add cost considerations. CrateDB, Exasol, and QuestDB are among the options to assess. As you compare, consider the data sources and query patterns your work involves, along with the deployment approach that fits your environment.
28 OLAP databases ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
