A naive key-value Database as the project of Storage Technology Foundations course.

You can choose CMake or Makefile to build this project. It is recommended to use CMake.

mkdir build && cd build
cmake .. && make

make
cd test && ./build.sh && cd ..
cd bench && ./build.sh && cd ..

Or you can use make TARGET_ENGINE=engine_example for the example engine.

The program will open lots of files, make sure that your ulimit is sufficient or the it will throw assertion errors.

Run ulimit -n $(ulimit -Sn) to set the open file limit to the maximum value allowed by the system.

Go to your build output directory (build for CMake and . for Makefile), then execute:

cd test
./{single_thread,multi_thread,crash}test # for CMake
./run_tests.sh # for Makefile

If the program exits immediately, make sure data dir exists.

Also go to your build output directory:

./bench/bench THREAD_NUM READ_RATIO IS_SKEW
