单条索引生成,速度较慢 elastic.php
<?php
use Elasticsearch\ClientBuilder;
require 'vendor/autoload.php';
include('pinyin.php');
ini_set('memory_limit','10280M');
$start = "开始时间:" . time() . PHP_EOL;

$client = ClientBuilder::create()->build();
$dict = array_map(function($str){
return str_ireplace('.', '', $str);},
array_keys(json_decode(file_get_contents('./dict.txt.cache.json'),
true)

批量索引生成 elasticBulk.php
<?php

use Elasticsearch\ClientBuilder;

$connectionPool = '\Elasticsearch\ConnectionPool\StaticNoPingConnectionPool';

$client = ClientBuilder::create()
->setRetries(10)//重试次数,默认重试次数为集群节点数
->setConnectionPool($connectionPool)
->setSelector($selector)
->build();
$dict = array_map(function($str){
return str_ireplace('.', '', $str);},
array_keys(json_decode(file_get_contents('./dict.txt.cache.json'),

echo $start = "开始时间:" . time() . PHP_EOL;
createData($client, $dict);
echo $end = "结束时间:" . time() . PHP_EOL;
echo "耗时:" . $end - $start;
function createData($client, $dict){
$bulk = array('index'=>'my_index4','type'=>'my_type4');
//bulk批量生成
for($j = 0;$j <= 99; $j++) {
for($i = $j * 50000 + 1; $i <= $j * 50000 + 50000; $i ++) {
$bulk['body'][]=array(
'index' => array(
'_id'=>$i
),
'type' => 'blocking'
);
$bulk['body'][] = [
'user_id' => mt_rand(100000000, 2000000000).'@qq.com',
'name' => $tmpname = $dict[mt_rand(1000,360000)],
'py' => \Utils\Pinyin::conv($tmpname),
'phone' => array_rand(array_flip([13,15,17,18])) . mt_rand(100000000, 999999999),
'mail' => substr(
str_shuffle(
"0123456789abcdefghijklmnopqrstuvwxyz"),
0, mt_rand(5,20)
) . '@' . array_rand(
array_flip(
[
'163.com',
'126.com',
'yeah.net',
'qq.com',

array_pad([], mt_rand(2,5), '')

}
$client->bulk($bulk);
//进度统计
print($j + 1).'%'.PHP_EOL;
}
}
1.单条性能约100条/s , 批量性能约5000条/s
2.单节点批量处理一次性bulk数据上限35万,否则报错:PHP Fatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\NoNodesAvailableException' with message 'No alive nodes found in your cluster
3. 500万全真模拟数据占空间2G
4.查询性能:
第一次稍慢,但在1秒以内
第二次极速
