Towards Polyglot Data Stores -- Overview and Open Research Questions

Understand

Nowadays, data-intensive applications face the problem of handling heterogeneous data with sometimes mutually exclusive use cases and soft non-functional goals such as consistency and availability.

• Since no single platform copes everything, various stores (RDBMS, NewSQL, NoSQL) for different workloads and use-cases have been developed.
• However, since each store is only a specialization, this motivates progress in polyglot data management emerged new systems called Mult- and Polystores.
• They are trying to access different stores transparently and combine their capabilities to achieve one or multiple given use-cases.
