HurmaDB is a key-value storage with REST interface based on RocksDB. It was originally created in 2017 as a DBMS for educational purposes. Currently, this is a just-for-fun project.

How to build, test and run

Install all dependencies:

sudo apt install cmake g++ libpcre3-dev librocksdb-dev python3-pip \
  lcov doxygen clang-format

Install and configure virtualenvwrapper:

sudo pip3 install virtualenv virtualenvwrapper
echo 'export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3' >> ~/.bashrc
echo 'source /usr/local/bin/' >> ~/.bashrc

Create a virtualenv:

mkvirtualenv hurmadb
workon hurmadb

Install all Python dependencies into the virtualenv:

pip install -r requirements.txt

Build HurmaDB:

git clone
cd hurmadb
git submodule init
git submodule update
mkdir build
cd build
cmake ..
make -j2

Build the documentation:

firefox doxygen/html/index.html

Run tests:

make test

Run a benchmark:

./hurmadb -h 8080
curl -XPUT -d '{"Some":"RandomData123"}' localhost:8080/v1/kv/123 -D - -o -
wrk -t10 -c10 -d10s http://localhost:8080/v1/kv/123

Run under Valgrind:

valgrind ./hurmadb -h 8080

workon hurmadb
HURMADB_HTTP_PORT=8080 make test
curl -XPUT http://localhost:8080/v1/_stop
