2013 Proceedings of the VLDB Endowment  
With this proposal, we aim to demonstrate PAQO, a version of PostgreSQL's query optimizer that we have modified to produce plans that respect constraints specified through PASQL while optimizing userspecified  ...  To address these types of issues, we have created a framework that empowers users with the ability to specify constraints on the kinds of plans that can be produced by the optimizer to evaluate their queries  ...  This work was further partially supported by a gift from EMC/Greenplum.  ...

PAQO: Preference-aware query optimization for decentralized database systems

2014 2014 IEEE 30th International Conference on Data Engineering  
Our Preference-Aware Query Optimizer (PAQO) upholds both strict requirements and partially ordered preferences that are issued alongside of the queries that it processes.  ...  A consequence of this model is that should a user ever want to specify some aspect of how their queries are evaluated (e.g., a preference to read data from a specific replica, or a requirement for all  ...  It was further partially supported by a gift from EMC/Greenplum. We thank the reviewers for their insightful feedback.  ...
