             Summary: Apache Wayang(Incubating): Cost Model Learner Using Machine learning
                 Key: COMDEV-473
                 URL: https://issues.apache.org/jira/browse/COMDEV-473
             Project: Community Development
          Issue Type: New Feature
          Components: GSoC/Mentoring ideas
            Reporter: Bertty Contreras


*Synopsis*

The current Apache Wayang (Incubating) uses a cost model to select the right set of platforms while optimize query plans. Often, the initial cost model could be ineffective after some time, and a calibration of the cost model is required again. The goal is to create a pipeline that starts a ML pipeline that starts the calibration of the cost model automatically and uses the logs of the previous query executions to get refine the cost model so that it follows the workload that interacts with the Apache Wayang (Incubating) environment.

 

*Benefits to Community*

The benefits for the community will have an AI pipeline for automatic, dynamic cost model calibration in query optimizers; We will use Apache Wayang(Incubating) as our playground. As a result, the experience of the users of Apache Wayang(Incubating) will improve by helping them to automatically tune their cost models and adatp to the current query workload.

 

*Deliverables*

The delivery expected is an adaptation for the paper "Zero-Shot Cost Models for Out-of-the-box Learned Cost Prediction"[1], where the authors assume an ML-Cost-Model. Still, in this case, the idea needs modifications to run in the current setup of Apache Wayang(Incubating).

 

The step expected are the following:
 * Understand the paper [1]
 * Get into the cost model of Apache Wayang
 * Discuss and design the process for the dynamic cost-model
 * Implement the feature of dynamic cost-model
