Type Parameters:
K - type of the key
V - type of the value

GenericMapStore is an implementation of MapStore built on top of Hazelcast SQL engine.

It works with any SQL connector supporting SELECT, INSERT, UPDATE and DELETE statements.

Usage:

First define data connection, e.g. for JDBC use JdbcDataConnection: 

Config config = new Config();
 config.addDataConnectionConfig(
   new DataConnectionConnection("mysql-ref")
     .setType("Jdbc")
     .setProperty("jdbcUrl", dbConnectionUrl)
 );

Then create a Map with MapStore using the GenericMapStore implementation: 

MapConfig mapConfig = new MapConfig(mapName);
 MapStoreConfig mapStoreConfig = new MapStoreConfig();
 mapStoreConfig.setClassName(GenericMapStore.class.getName());
 mapStoreConfig.setProperty(GenericMapStore.DATA_CONNECTION_REF_PROPERTY, "mysql-name");
 mapConfig.setMapStoreConfig(mapStoreConfig);
 instance().getConfig().addMapConfig(mapConfig);

The GenericMapStore creates a SQL mapping with name "__map-store." + mapName. This mapping is removed when the map is destroyed.

Note : When GenericMapStore uses GenericRecord as value, even if the GenericRecord contains the primary key as a field, the primary key is still received from @{link IMap method call
