MasterSource/MasterFields behavior

Question:

Are MasterSource/MasterFields like a filter in the sense that the ClientDataSet retrieves all records and filters for those records that match the linked fields?

Answer:

It really depends on how you have it set up.  If you set 
PacketRecords to -1 then yes, that is the way it works.
If you have PacketRecords to 0 and FetchOnDemand as True,
then it will use Provider.SetParams and fetch just the
records that match the master.
