My question is related to locking. One of the primary reasons we want to have a separate database for read-only reporting is that we do not want reads to be going directly against our production database. When reading unchanged data from a snapshot, are read locks placed on the primary database? If so, are these locks the same as the locks placed if I had directly read from the primary database? If the locking is the same for unchanged data, using snapshots in my eyes may result in similar locking issues. If this is the case, the feature has lost some of its luster.
