Is TiDB's code base entirely based on Go language?

TiDB is an open source distributed database system equipped with distributed storage engine TiKV and query layer TiDB, aiming to provide users with high-performance and highly scalable database solutions. . The TiDB code base implements the core functions of the database, while TiKV is responsible for persistent data storage and transaction processing. In the TiDB code base, most of the code is written based on the Go language. This is also one of the original design intentions of the TiDB project, because the Go language has efficient concurrency performance and rich standard library support.

First, let us verify whether it is completely based on the Go language by looking at some sample code in the TiDB code base.

// 一个简单的示例函数，用于连接到数据库
func connectToDB() {
    // 使用 Go 语言的数据库驱动包
    db, err := sql.Open("mysql", "username:password@tcp(localhost:3306)/database")
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()

    // 查询数据库数据
    rows, err := db.Query("SELECT * FROM table")
    if err != nil {
        log.Fatal(err)
    }
    defer rows.Close()

    for rows.Next() {
        var id int
        var name string
        err := rows.Scan(&id, &name)
        if err != nil {
            log.Fatal(err)
        }
        fmt.Printf("ID: %d, Name: %s
", id, name)
    }
}

The above code example shows a simple function using Go language to connect to the database and query data. In the TiDB code base, similar code snippets are distributed in various modules, covering core database functions from SQL parsing to transaction processing.

In addition to core database functions, TiDB's code base also contains a large amount of code related to distributed systems, such as load balancing, distributed transaction processing, data sharding, etc. These codes are also implemented based on the Go language and utilize its powerful concurrent programming capabilities to achieve efficient distributed data processing.

In general, TiDB's code base is almost entirely written in the Go language, which gives the project high consistency and code quality. At the same time, the lightweight thread model and efficient garbage collection mechanism of the Go language also provide TiDB with good performance, making it a popular distributed database system.
