Managing the result set is now the responsibility of the external system e.g. Paging, filtering, and sorting of the external list data needs to be taken care by the source system before it is sent to SharePoint. The claim is that this would improve the performance of external lists

Filtering needs to be defined in the External Content Type definition
Sorting is done on the entire result set within SharePoint
Paging is managed in a roundabout way by using a filter
|
Methods, which contain the T-SQL or Web service methods that retrieve the entity data. Entities can contain multiple methods and can optionally have parameters and filters defined that Business Data Catalog users can use to filter results
|
By defining data source filter on BDC model, the filtering is expected to happen at source side
|
Filtering needs to be defined in the External Content Type definition
|
Filtering is to be specified in T-SQL / Web Service method parameters
|
Similar to filters, sorting can also be configured to happen at source by specifying in the BDC model. This sorting is expected to happen on the external source
