Description

I can't perform simple query to druid using github.com/apache/calcite-avatica-go. 

Code:

package main

import (
	"database/sql"
	"fmt"
	_ "github.com/apache/calcite-avatica-go/v4"
)

func main() {
	db, err := sql.Open("avatica", "http://********:8888/druid/v2/sql/avatica/")
	if err != nil { panic(err) }
	rows, err := db.Query(`SELECT * FROM sys.servers`)
	if err != nil { panic(err) }
	defer func() {
		if err := rows.Close(); err != nil { panic(err) }
	}()
	for rows.Next() {
		var server, host float64
		err = rows.Scan(&server, &host)
		if err != nil { panic(err) }
		fmt.Printf("server: %v, host: %v\n", server, host)
	}
}

Console:

panic: proto: can't skip unknown wire type 4
goroutine 1 [running]:main.main() main.go:17 +0x30d
Process finished with exit code 2
