Automatic Summary Recommendations

To make the most of the Smart Query acceleration for analytics it is important to select the right set of summaries. However, defining these summaries manually can be difficult in some cases. The AI & Denodo Assistant FeaturePack for the Denodo Platform includes the Summary Recommendations tool, which makes this process much easier. This tool analyzes information about real queries and automatically recommends summaries to accelerate that workload.

Note

This feature is only available with the subscription bundle Enterprise Plus. To find out the bundle you have, open the About dialog of Design Studio. See more about this in the section Denodo Platform - Subscription Bundles.

Process Setup Overview

This process includes three phases:

  1. Monitor the environment that you want to optimize in order to generate valuable information from the queries executed on your production servers. To gather the necessary information use the monitoring feature of the Solution Manager making sure the monitor ‘Query blocks’ is selected. For more information about this step see section How to Monitor an Environment for Summary Recommendations.

  1. Make the logs available to the Virtual DataPort server (only the first time you run the Summary Recommendations tool): in the Virtual DataPort server you will use to launch this tool, import the VQL file <DENODO_HOME>/resources/vdp/query_acceleration/summary_recommendations_db.vql.

    This template creates a database “query_acceleration” containing the interfaces i_queryblock_notification and i_request_notification.

    Adapt the implementations to access the information from the “Queries” and “Query blocks” monitors respectively.

    See the section Make the Logs Information Available to a VDP Server for more information about this step.

  2. Generate recommendations: log in to Design Studio and click the menu Tools > Query optimizations > Summary Recommendations. Select the date range of the queries you want to consider and click Suggest.

    For more information about this step see section Run the Summary Recommendations Tool.
