Fetching Strategies

There are four fetching strategies
1. fetch-”join” = Disable the lazy loading, always load all the collections and entities.
2. fetch-”select” (default) = Lazy load all the collections and entities.
3. batch-size=”N” = Fetching up to ‘N’ collections or entities, *Not record*.
4. fetch-”subselect” = Group its collection into a sub select statement.
