Moneway Company Challenge - Transaction Simulation with Balance Update

Build and Run

Build project

./build.sh

Run project

sudo docker run -it scylladb ./balance ./transaction

Project architecture

The project is divided into four parts :

• Api (api directory)
• Database (scylladb directory)
• Balance service (services/balance directory)
• Transaction service (services/transaction directory)

Api part

This part contains protobuf files :

• balance.proto
• transaction.proto

Generate proto files

protoc --go_out=plugins=grpc:. ./api/v1/transaction.proto protoc --go_out=plugins=grpc:. ./api/v1/balance.proto

Database

The database is a scyllaDB database, the directory only contain a dockerfile in ordre to run it and a wrapper to create a keyspace "bank"

Build and run

sudo docker build -t scylladb . sudo docker run -it scylladb

The database is running on localhost:9042

Balance service

This service update the balance of an account and communicate with transaction service

• db directory contains models and connections function
• proto directory contains grpc server and service functions

Build and run

go build -o balance ./services/balance/main.go ./balance

The balance service is running on localhost:8080

Transaction service

This service creates and update transaction and communicates with balance service

• db directory contains models and connections function
• proto directory contains grpc server, client and service functions

Build and run

go build -o transaction ./services/trnasaction/main.go ./balance

The transaction service is running on localhost:8081
