Buffer is nothing but a memory area.

table is buffered means that table information is available on application server. when you call data from database table it will come from application server.

transperent and pooled tables are buffered. cluster tables can not buffered

Buffering

You must define whether and how a table is buffered in the technical settings for the table. There are three possibilities here:

1. Buffering not permitted: Table buffering is not permitted, for example because application programs always need the most recent data from the table or the table is changed too frequently.

2.Buffering permitted but not activated: Buffering is permitted from the business and technical points of view. Applications which access the table execute correctly with and without table buffering.

Whether or not table buffering will result in a gain in performance depends on the table size and access profile of the table (frequency of the different types of table access).

Table buffering is deactivated because it is not possible to know what these values will be in the customer system. If table buffering would be advantageous for the table size and access profile of the table, you can activate it in the customer system at any time.

3.Buffering activated: The table should be buffered. In this case you must specify a buffering type.
