We present our use of Julia to build a new kind of cloud-native relational database management system for knowledge graphs. We motivate the need for a database that excels in supporting workloads that mix data management, machine learning, and graph analytics. We explain how Julia's unique features enabled us to build a high-performance database with less time and effort. We also discuss how we contribute to and leverage the Julia ecosystem.
After a brief overview of knowledge graphs and the relational paradigm we describe the foundational design principles and implementation philosophy of the RelationalAI system:
- Leverage: how we use cloud computers and modern compilers to reduce engineering effort
- Brains and brawn: how we improve the asymptotic performance of our system with new algorithms that exploit problem structure
- Aggressive simplification and consolidation: how we build on 5 core capabilities that compose elegantly in ways that cover a broad range of use cases.
We then review the first 3 of these 5 core capabilities (the query compiler, incremental maintenance, immutable structures) and touch on the remaining 2 (worst-case optimal joins and semantic optimization)
