Understanding a Rowset Cache
Many PeopleSoft applications use a metadata based design, where application PeopleCode reads metadata from a database record or some other source, then presents the user with an interface that is modified based on the metadata.
PeopleTools stores application data in a database cache to increase system performance. The RowsetCache class enables you to access this memory structure, created at runtime, and shared by all users.
Data that would qualify as metadata and would be appropriate for the RowsetCache class would be data that was commonly used yet fairly static, for example, country or currency tables.
The RowsetCache class does not provide a mechanism for synchronizing the data between database tables and the cache. If the underlying data changes, you must repopulate the rowset cache.
Note: Non-base language users may see different performance due to language table considerations.
