Build Instructions 🔨

1. Install the dependencies 🍰

INFO: installs mongo-c-driver, mongo-cxx-driver and mongodb

sudo sh install_dependencies.sh

2. Test your installation 🧪

$ g++ --std=c++11 test.cpp $(pkg-config --cflags --libs libmongocxx) -Wl,-rpath,/usr/local/lib
$ ./a.out

3. Build 🚀

sudo sh build.sh

---

Running 🎯

1. create a replica set in mongo

$ mongod --dbpath /data/db --replSet "rs0"

2. open a mongo shell and initiate the replica set

rs.initiate()

3. start the server

$ bazel run //server:zirconium_server --       

4. start the client

$ bazel run //:zirconium_client -- --username=meow --pin=123456 --deposit=10

Testing

1. Run Mongod

$ mongod --dbpath /data/db --replSet "rs0"

2. Run Mongo Client

$ mongo

3. Create a replica set

rs.initiate()

4. Open Mongo Compass and connect to our database

Use this URI

mongodb://localhost:27017/?replicaSet=rs0&readPreference=primary&appname=MongoDB%20Compass&ssl=false

5. Load the data from test_data.json

ADD DATA -> Import File

6. Start the server

$ ./bazel-bin/server/zirconium_server --config server/server.config

7. Now run test_transactions.sh

Make sure to install parallel by sudo apt install parallel

$ seq 10 | parallel -j 10 --workdir $PWD ./test/test_transactions.sh {}
