The factory classes have the duty to create the column family manager.
- ColumnFamilyManagerAsyncFactory
- ColumnFamilyManagerFactory
The ColumnFamilyManagerAsyncFactory and ColumnFamilyManagerFactory creates the manager synchronously and asynchronously respectively.
ColumnFamilyManagerFactory factory = //instance
ColumnFamilyManagerAsyncFactory asyncFactory = //instance
ColumnFamilyManager manager = factory.get("database");
ColumnFamilyManagerAsync managerAsync = asyncFactory.getAsync("database");The factories were separated intentionally, as not all databases support synchronous and asynchronous operations.
