ultra_table

Overview

Ultra_table provides a possibility to quickly build an in-memory table, It has good performance and high scalability, The current version already supports serialization of gogoproto and easyjson, The most important thing is that he is based on the latest golang 1.18 implementation, which is the implementation of go generics. We try to apply sdk to internal applications. Requires Go 1.18 or newer.

Getting started

To install Ultra_table, use go get:

$ go get github.com/longbridgeapp/ultra-table

Example

package main

import (
	"log"

	ultra_table "github.com/longbridgeapp/ultra-table"
	"github.com/longbridgeapp/ultra-table/test_data/easyjson"
	"github.com/longbridgeapp/ultra-table/test_data/pb"
)

func main() {
	baseEasyjson() //serialization based easyjson
	basegogo()     //serialization based gogo protobuf
}

func baseEasyjson() {
	table := ultra_table.New[*easyjson.Person]()

	err := table.Add(&easyjson.Person{
		Name:     "jacky",
		Phone:    "+8613575468007",
		Age:      31,
		BirthDay: 19901111,
		Gender:   0,
	})
	if err != nil {
		log.Fatal(err)
	}
	err = table.Add(&easyjson.Person{
		Name:     "rose",
		Phone:    "+8613575468008",
		Age:      31,
		BirthDay: 19901016,
		Gender:   1,
	})
	if err != nil {
		log.Fatalln("easyjson", err)
	}

	infos, err := table.GetWithIdx("Phone", "+8613575468007")
	if err != nil {
		log.Fatalln("easyjson", err)
	}
	for i := 0; i < len(infos); i++ {
		log.Printf("easyjson %+v \n", infos[i])
	}

	_, err = table.GetWithIdxIntersection(map[string]interface{}{
		"Age":  31,
		"Name": "rose",
	})
	log.Println("easyjson", err)
}

func basegogo() {
	table := ultra_table.New[*pb.Person]()

	err := table.Add(&pb.Person{
		Name:     "jacky",
		Phone:    "+8613575468007",
		Age:      31,
		BirthDay: 19901111,
		Gender:   pb.Gender_men,
	})
	if err != nil {
		log.Fatal(err)
	}
	err = table.Add(&pb.Person{
		Name:     "rose",
		Phone:    "+8613575468008",
		Age:      31,
		BirthDay: 19901016,
		Gender:   pb.Gender_women,
	})
	if err != nil {
		log.Fatalln("gogo", err)
	}

	infos, err := table.GetWithIdx("Phone", "+8613575468007")
	if err != nil {
		log.Fatalln("gogo", err)
	}
	for i := 0; i < len(infos); i++ {
		log.Printf("gogo %+v \n", infos[i])
	}

	_, err = table.GetWithIdxIntersection(map[string]interface{}{
		"Age":  31,
		"Name": "rose",
	})
	log.Println("gogo", err)
