Only the record that was really accessed is buffered. When Full Buffering is used then either entire table is buffered or none of the records will be buffered. When a single record is accessed, the entire data/record of that table is buffered. By Buffering we mean that all the record is in the buffer table.
What is full buffering in SQL Server?
When a single record is accessed, the entire data/record of that table is buffered. By Buffering we mean that all the record is in the buffer table. Larger table is rarely written and frequently read like Master Table, and then we need to use Full Buffering. For small tables like customizing tables that are mainly read.
