Interface DataPersister<T>

All Superinterfaces:

DataProvider<T>, ManagedDataSource<T>

All Known Subinterfaces:

ExternalDataSource<T>

public interface DataPersister<T>
extends DataProvider<T>

DataPersister is responsible for the persistency of the space data in external data source.

This interface should be implemented for non-transactional single operations applications.
Single operations - write,update and remove are used for objects with UID.
For batch operations and transactions use the BulkDataPersister.
