Field-programmable gate arrays (FPGAs) are a promising technology that can be used in database systems. In this demonstration we show Glacier, a library and a compiler that can be employed to implement streaming queries as hardware circuits on FPGAs. Glacier consists of a library of compositional hardware modules that represent stream processing operators. Given a query execution plan, the compiler instantiates the corresponding components and wires them up to a digital circuit. The goal of this demo is to show the flexibility of the compositional approach.
