To optimize the performance when retrieving a large number of rows from a Data Extension via the API:

Use a SimpleFilterPart to retrieve small sets of relevant data (A) - This approach helps in fetching only the necessary data by applying filters, thus reducing the amount of data transferred and processed.

Use the ContinueRequest feature (C) - This feature in the SOAP API allows for pagination of results, making it possible to handle large sets of data in manageable chunks.

Profile attributes like AGE in Profile Manager are not directly accessible via the _Subscribers data view or _EnterpriseAttribute data view. To retrieve subscribers over 30 years of age, creating a filtered Group based on the AGE attribute is the most effective method.

Salesforce Subscriber Filters and Groups

To build an audience by identifying subscribers who opened a specific email, the developer should use the following query:

SELECT SubscriberKey FROM _Open WHERE JobID = '1234'

This query selects the SubscriberKey from the _Open data view where the JobID matches the specific email send.
