go sonic

Gunakan klien untuk backend pencarian sonik

Paket ini mengimplementasikan semua perintah untuk bekerja dengan sonic. Jika ada satu yang hilang, buka terbitannya! :)

Memasang

go get github.com/expectedsh/go-sonic

Contoh

 package main

import (
	"fmt"
	"github.com/expectedsh/go-sonic/sonic"
)

func main () {

	ingester , err := sonic . NewIngester ( "localhost" , 1491 , "SecretPassword" )
	if err != nil {
		panic ( err )
	}

	// I will ignore all errors for demonstration purposes

	_ = ingester . BulkPush ( "movies" , "general" , 3 , []sonic. IngestBulkRecord {
		{ "id:6ab56b4kk3" , "Star wars" },
		{ "id:5hg67f8dg5" , "Spider man" },
		{ "id:1m2n3b4vf6" , "Batman" },
		{ "id:68d96h5h9d0" , "This is another movie" },
	})

	search , err := sonic . NewSearch ( "localhost" , 1491 , "SecretPassword" )
	if err != nil {
		panic ( err )
	}

	results , _ := search . Query ( "movies" , "general" , "man" , 10 , 0 )

	fmt . Println ( results )
}

Tolok ukur secara massal

Metode BulkPush dan BulkPop menggunakan kumpulan koneksi khusus dengan algoritma pengiriman goroutine. Ini patokannya (file sonic/ingester_test.go):

Keamanan Benang

Pengemudi itu sendiri tidak aman untuk thread. Anda dapat menggunakan kunci atau saluran untuk menghindari kerusakan.

 package main

import (
	"fmt"

	"github.com/expectedsh/go-sonic/sonic"
)

func main () {
	events := make ( chan [] string , 1 )

	event := [] string { "some_text" , "some_id" }
	tryCrash := func () {
		for {
			// replace "event" with whatever is giving you events: pubsub, amqp messages…
			events <- event
		}
	}

	go tryCrash ()
	go tryCrash ()
	go tryCrash ()
	go tryCrash ()

	ingester , _ := sonic . NewIngester ( "localhost" , 1491 , "SecretPassword" )

	for {
		msg := <- events
		// Or use some buffering along with BulkPush
		ingester . Push ( "collection" , "bucket" , msg [ 1 ], msg [ 0 ])
	}
}
