              p.hub1__text A key-value store is a data storage software. It stores, retrieves, and manages data as a set of unique keys. Each one is associated with one and only one value.
              h2.h5.hub1__title.hub1__titleend How a key-value store works
              p.hub1__text A key-value store, or a key-value database, holds a collection of data records in various fields. The data records have unique keys to retrieve and modify records quickly.

            h2.grid4__h2.h5.key4__h2 With Apache Ignite, a key-value store can cache data in memory and persist it on disk
            .grid4__block
               p.grid4__text The <a href="/arch/native-persistence.html">native persistence</a> feature eliminates the time-consuming cache warm-up step as well as the data reloading phase from external databases.
               p.grid4__text.pt-1 Since native persistence always keeps a full copy of data on disk, you are free to cache a subset of records in memory. 
               p.grid4__text.pt-1 If a required data record is missing in memory, then Ignite reads it from disk automatically, regardless of the API you use.
