Examples of MapStore

com.hazelcast.core.MapStore
Hazelcast distributed map implementation is an in-memory data store but it can be backed by any type of data store such as RDBMS, OODBMS, NOSQL or simply a file based data store.
IMap.put(key, value) normally stores the entry into JVM's memory. If MapStore implementation is provided then Hazelcast will also call the MapStore implementation to store the entry into a user defined storage such as RDBMS or some other external storage system. It is completely up to the user how the key-value will be stored or deleted.
Same goes for IMap.remove(key)
Store implementation can be called synchronously (write-through) or asynchronously (write-behind) depending on the configuration.
