Abstract

Polystore databases allow to store data in di erent formats and data models and o er several query languages. While such polystore systems are highly beneficial for various nalytical workloads, they provide limited support for transactional and for mixed OLTP and OLAP workloads, the latter in contrast to hybrid transactional and analytical processing (HTAP) systems. In this paper, we present Polypheny-DB, a modular polystore that jointly provides support for analytical and transactional workloads including update operations and that thus takes one step towards bridging the gap between polystore and HTAP systems.
