Purpose

Explanation of concept of SQL  / Cell Offload Processing on Exadata Database Servers.

Exadata database servers can offload data-intensive SQL operations to Oracle Exadata Storage Servers.
Moving the SQL processing to Oracle Exadata Storage Servers enables data filtering and processing to occur immediately and in parallel across all storage servers as data is read from disk.
Exadata storage offload reduces database server CPU consumption and greatly reduces the amount of data moved between the storage and database servers.
