The buffering type defines which table records are loaded into the buffer of the application server when a table record is accessed. The following buffering types exist:
The system loads all the records of the table into the buffer when one record of the table is accessed.
When a record of the table is accessed, all the records having this record in the generic key fields (part of the table key that is left-justified, identified by specifying a number of key fields) are loaded into the buffer.
Only the records of a table that are really accessed are loaded into the buffer.
