What tools and databases have you worked with?

In working with Go, I have used various tools and databases, including:

• Relational databases: PostgreSQL, MySQL. I used database/sql drivers with lib/pq for PostgreSQL and go-sql-driver/mysql for MySQL.
• NoSQL databases: Redis (via go-redis), MongoDB (via the official mongo-go-driver).
• Migration tools: golang-migrate/migrate.
• Monitoring and logging tools: Prometheus, Grafana, Logrus.

Example of connecting to PostgreSQL:

import (
    "database/sql"
    _ "github.com/lib/pq"
)

func connect() (*sql.DB, error) {
    connStr := "user=username dbname=mydb sslmode=disable"
    return sql.Open("postgres", connStr)
}

I also used message queue tools such as RabbitMQ and Kafka.
