Data Flow : How bufferization happens ?

Data flow

When data is requested from a bufferized Connection, the following happens :

• If Buffer Refresh is not enabled : data is retrieved from the buffer.
• If Buffer Refresh is enabled :
  • If the buffer is valid ⇒ data is retrieved from the buffer.
  • If the buffer is out of date ⇒ the buffer is refreshed by data from the Connection (the Web connection, the CSV file, etc…).

Content of the Alpana buffer database

Alpana Server creates, deletes and updates tables in the buffer database.

This is a purely internal mechanism and should not be relied on by external tools.

!You shouldn’t use the buffer database for other purposes, otherwise you might lose your data.
