> *Background*
> Existing Export API navigates the graph structure and get all the connected
> entities as part of export. The API is geared toward exporting of entire
> database and not parts of the database.
> *Scenario*
> It is possible to specify Export of 1 table. The resulting ZIP however,
> contains the entire database and all other tables in the database to be
> exported. Alternately stated, it is not possible to export subset of the
> graph of which the entity is part of.
> This behavior impacts Import, as more entities get imported than needed.
> *Resolution*
> While the existing approach is useful, the user should be allowed to specify
> the scope of the export operation.
> The existing _ExportRequest.options_ could potentially have an option that
> indicate the scope.
> {quote}
> options
> FETCH = FULL | CONNECTED
> {quote}
> _FETCH = FULL_ All entities directly and indirectly entities are fetched.
> _FETCH = CONNECTED_ All entities directly connected are fetched.
> Examples:
> {code:title=options.FULL}
> {
> "itemsToExport": [
> {
> "typeName": "DB_v1",
> "uniqueAttributes": {
> "name": "Sales"
> }
> }
> ],
> "options": {
> "FETCH": "FULL"
> }
> }
> {code}
> {code:title=options.CONNECTED}
> {
> "itemsToExport": [
> {
> "typeName": "Table_v1",
> "uniqueAttributes": {
> "name": "customer_view"
> }
> }
> ],
> "options": {
> "FETCH": "CONNECTED"
> }
> }
> {code}
