A columnar database stores each column separately on disk. This allows high compression of “runs” of data — the same value repeated a number of times in a column can be efficiently stored. A wide-column database is a row-based data store that supports a complex index comprised of multi...
In-memory databases store and manipulate data in the memory tier of an application rather than on a storage disk. This type of structure is often matched with columnar store functionality and vectorized query plans to accelerate analytic queries. This type of data store is good at supporting ligh...
