Go gRPC Service with ScyllaDB

This repository contains a microservice written in Go that utilizes gRPC for communication and ScyllaDB as the database. The service manages movie information in a Keyspace named "bookmyshow" with a table named "movies."

Prerequisites

• Go installed on your machine
• Protocol Buffers (protobuf) compiler installed
• ScyllaDB installed and running

Setup

1. Clone the repository:

   git clone https://github.com/Jitender271/go-grpc-service.git
   cd go-grpc-service
   

2. Install Dependencies

go install \
    github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway \
    github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-openapiv2 \
    google.golang.org/protobuf/cmd/protoc-gen-go \
    google.golang.org/grpc/cmd/protoc-gen-go-grpc

go mod vendor
   or
go mod tidy

3. Compile Protocol Buffers:

protoc --proto_path= proto/*.proto --go_out=resources/ --go-grpc_out=resources/ --grpc-gateway_out=resources/

ScyllaDB Configuration

1. Connect to your ScyllaDB instance(on Docker) and create the keyspace:

CREATE KEYSPACE IF NOT EXISTS bookmyshow WITH REPLICATION = {'class': 'SimpleStrategy', 'replication_factor': 1};

2. Create the "movies" table:

   CREATE TABLE IF NOT EXISTS movies (
    movie_id TEXT,
    name TEXT PRIMARY KEY,
    genre TEXT,
    description TEXT,
    rating TEXT,
    );

Running the Service

go build

go run main.go

Usage

Use a gRPC client to interact with the service. See the proto/movie.proto file for service definition.
