Tell us about your current project — what are you working on?

In my current project, I am working on a high-load microservice in Go that handles real-time data processing and aggregation. We use gRPC for communication between services and PostgreSQL with TimescaleDB for storing time series data. The main tasks include optimizing performance, writing unit and integration tests, as well as implementing new APIs for interaction with the frontend and external systems.

Example code for a gRPC service in Go:

package main

import (
    "context"
    "log"
    "net"

    pb "example.com/project/proto"
    "google.golang.org/grpc"
)

type server struct {
    pb.UnimplementedDataServiceServer
}

func (s *server) GetData(ctx context.Context, req *pb.DataRequest) (*pb.DataResponse, error) {
    // Request processing logic
    return &pb.DataResponse{Data: "response data"}, nil
}

func main() {
    lis, err := net.Listen("tcp", ":50051")
    if err != nil {
        log.Fatalf("failed to listen: %v", err)
    }
    s := grpc.NewServer()
    pb.RegisterDataServiceServer(s, &server{})
    if err := s.Serve(lis); err != nil {
        log.Fatalf("failed to serve: %v", err)
    }
}
