# AQuery
Yet another slow query analyzer for Go.
[Description in Japanese](https://anqou.net/teqblog/2020/10/go%E7%94%A8sql%E3%82%B9%E3%83%AD%E3%83%BC%E3%82%AF%E3%82%A8%E3%83%AA%E8%A7%A3%E6%9E%90%E3%83%84%E3%83%BC%E3%83%ABaquery%E3%82%92%E6%9B%B8%E3%81%84%E3%81%A6isucon10%E3%81%AE%E6%9C%AC%E9%81%B8%E3%81%AB%E5%87%BA%E3%81%9F%E3%82%89fail%E3%81%97%E3%81%9F/).
## Install
Rewrite your code:
```go
import "github.com/ushitora-anqou/aquery"
func main() {
thresholdSlowQuery, err := time.ParseDuration("0ms")
handler := aquery.RegisterTracer(thresholdSlowQuery)
http.DefaultServeMux.Handle("/debug/aquery", handler)
go func() {
log.Println(http.ListenAndServe("localhost:6060", nil))
}()
db, err := sql.Open("mysql:trace", "data source")
if err != nil {
log.Fatalf("Could not open db: %s", err.Error())
}
// Use db
}
```
Install aquery command, get the profile, and analyze it:
```
# I'll use optimized https://github.com/isucon/isucon9-final as a running example.
$ go get github.com/ushitora-anqou/aquery/aquery
$ curl "http://localhost:6060/debug/aquery?seconds=60" > query.gz
$ aquery/aquery -match-ct=isutrain -short-ct -col=100 isu9f1.gz | head -20
