In order to configure MPP to Presto and Impala, I would follow the below steps in the Virtual DataPort Administration Tool:
* Navigate to the Administration > Server configuration option. In the Queries optimization tab, enable the Automatic cost based optimization and Automatic simplification of queries option.
* Then select the datasource for Parallel Processing acceleration. It is possible to select the cache data source or a specific JDBC data source.
* For creating a [JDBC data source](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_data_sources_and_base_views/jdbc_sources/jdbc_sources#jdbc-sources) to support MPP, right-click on the database and navigate to New > Data Sources > JDBC.
* In the Configuration tab, click on the Connection tab and in the Database adapter select the required adapter for Presto or Impala.
* Specify the Presto or Impala related information such as Driver class path, Driver class,etc in the Configuration tab.
* To configure the MPP, click on the Read & Write tab and check the Use Bulk Data Load API checkbox.
* Then specify the relevant Hadoop information like file system, HDFS URI and server time zone.
* Click Test connection and save.
By performing the above steps, I will be able to configure the MPP in Denodo.
Refer to the [Configure VDP](https://community.denodo.com/kb/en/view/document/How%20to%20configure%20MPP%20Query%20Acceleration%20in%20Denodo#h.rktsq8j3bkws) and [MPP Query Acceleration: Sizing guidelines](https://community.denodo.com/kb/en/view/document/MPP%20Query%20Acceleration:%20Sizing%20guidelines) Knowledge Base Article for more information.
Hope this helps!
