Polypheny-DB

Polypheny-DB is a self-adaptive Polystore that provides cost- and workload aware access to heterogeneous data. As a Polystore, Polypheny-DB seamlessly combines different underlying data storage engines to provide good query performance independent of the type of workload.

If you want to learn more about Polypheny-DB, we recommend having a look on our website or on this paper.

Getting Started

The easiest way to setup Polypheny-DB is to use a release. Alternatively, you can use Polypheny Control to automatically build Polypheny-DB.

Roadmap

Credits

Polypheny-DB builds upon the great work of several other projects:

• Apache Avatica: A framework for building database drivers
• Apache Calcite: A framework for building databases
• HSQLDB: A relational database written in Java
• JavaCC: A parser generator
• Java Spark: A framework for building web services
• Project Lombok: A library which provides annotations for tedious tasks

Except for the first two, those projects are used "as is" and integrated as a library. Apache Avatica we forked and made some Polypheny-DB specific adjustments. From Apache Calcite we use parts of the code as foundation for Polypheny-DB.
