In Virtual DataPort, Cache module is used to store a local copy of the data retrieved from the data sources. This will help in reducing the impact of repeated queries hitting the data source and speeds up the data retrieval, especially with certain types of sources.
Also, Denodo Platform provides the “Denodo Incremental Cache Load Stored Procedure”. This stored procedure makes incremental additions with the new tuples and the updated ones to keep the cache view updated.
For more information, you can have a look at the documentation[ Denodo Incremental Cache Load Stored Procedure - User Manual](https://community.denodo.com/docs/html/document/denodoconnects/7.0/Denodo%20Incremental%20Cache%20Load%20Stored%20Procedure%20-%20User%20Manual).
Hope this helps!
