Summary: External Data Source (EDS) is a space component that provides advanced persistency capabilities for the space architecture.
OverviewExternal Data Source (EDS) is a space component that provides advanced persistency capabilities for the space architecture. GigaSpaces External Data Source provides the DataProvider/DataPersister interfaces (with a built in implementation using Hibernate) which can be used to store data in an existing data source and in the space. Data is loaded from the data source during space initialization (DataProvider), and from then onwards the application works with the space directly. Meanwhile, the data source is constantly updated with all the changes made in the space (DataPersister). Persistency can be configured to run in Synchronous or Asynchronous mode:
External Data Source InterfacesExternal Data Source interfaces are a set of interfaces that define the interaction between the space and the data source. For detailed information, see External Data Source API. GigaSpaces comes with a built in implementation of DataProvider and DataPersister called Hibernate External Data Source. The code below shows how it can be configured with a simple Space connecting to a central data source. See External Data Source Initial Load to allow the space to pre-load its data.
