# Henhouse
Henhouse is a fast time series DB that can compute sum, average, and variance
between any two time ranges in **basically** constant time.
DB stores a sums and sum of squares table along with actual values to provide
constant time computation between two time ranges.
Henhouse uses the old school embedded signal processing technique of using
streaming versions of computing mean and variance.
# Design
Read more about the system design: [DESIGN.md](docs/DESIGN.md).
# Building
Henhouse is built in C++ and runs on Linux and MacOS. See [build instructions](docs/BUILD.md)
for more information.
# Query Interface
Henhouse provides both a HTTP query service and a Graphite compatible input service.
You can read about how to use these services [here](src/service/README.md)
