Features

No dependency

More: https://github.com/smi2/phpClickHouse#features

Prerequisites

• PHP 8.1
• Hyperf = 3.1
• Clickhouse server

Installation

1. Install via composer

$ composer require tangwei/hyperf-clickhouse

1. Add new connection into your config/database.php:

    'clickhouse' => [
        'driver' => 'clickhouse',
        'host' => env('CLICKHOUSE_HOST'),
        'port' => env('CLICKHOUSE_PORT','8123'),
        'database' => env('CLICKHOUSE_DATABASE','default'),
        'username' => env('CLICKHOUSE_USERNAME','default'),
        'password' => env('CLICKHOUSE_PASSWORD',''),
        'https' => (bool)env('CLICKHOUSE_HTTPS',false),
        'settings' => [ // optional
            // 'max_partitions_per_insert_block' => 300,
        ],
        'pool' => [
            'min_connections' => 1,
            'max_connections' => 3,
            'connect_timeout' => 10.0,
            'wait_timeout'    => 3.0,
            'heartbeat'       => -1,
            'max_idle_time'   => 60,
        ],
    ],

Then patch your .env:

CLICKHOUSE_HOST=localhost
CLICKHOUSE_PORT=8123
CLICKHOUSE_DATABASE=default
CLICKHOUSE_USERNAME=default
CLICKHOUSE_PASSWORD=
# only if you use https connection
CLICKHOUSE_HTTPS=true

1. Used

You can use smi2/phpClickHouse functionality directly:

$client = \Tang\HyperfClickhouse\DB::query()->getClient();
$statement = $client->select('SELECT * FROM summing_url_views LIMIT 2');

More about $db see here: https://github.com/smi2/phpClickHouse/blob/master/README.md

Or use dawnings of Eloquent ORM (will be implemented completely)

1. Add model

<?php


namespace App\Models\Clickhouse;

use Tang\HyperfClickhouse\Model;

class MyTable extends Model
{
    // Not necessary. Can be obtained from class name MyTable => my_table
    protected string $table = 'my_table';

}

1. Add migration

<?php


class CreateMyTable extends \Tang\HyperfClickhouse\Migration
{
    /**
    * Run the migrations.
    *
    * @return void
    */
    public function up()
    {
        static::write('
            CREATE TABLE my_table (
                id UInt32,
                created_at DateTime,
                field_one String,
                field_two Int32
            )
            ENGINE = MergeTree()
            ORDER BY (id)
        ');
    }

    /**
    * Reverse the migrations.
    *
    * @return void
    */
    public function down()
    {
        static::write('DROP TABLE my_table');
    }
}

1. And then you can insert data

One row

$model = MyTable::create(['field_one' => 'model 1', 'field_two' => 1]);
# or
$model = MyTable::make(['field_one' => 'model 2']);
$model->field_two = 2;
$model->save();
# or
$model = new MyTable();
$model->fill(['field_one' => 'model 3', 'field_two' => 3])->save();

Or bulk insert

MyTable::query()->insert(['field_one' => 'model 11','field_two' => 11]);

1. Now check out the query builder

$rows = MyTable::query()->select(['field_one', \Tinderbox\ClickhouseBuilder\raw('sum(field_two)', 'field_two_sum')])
    ->where('created_at', '>', '2020-09-14 12:47:29')
    ->groupBy('field_one')
    ->getCollect();

Working with huge rows

You can chunk results like in Laravel

// Split the result into chunks of 30 rows 
$rows = MyTable::query()->select(['field_one', 'field_two'])
    ->chunk(30, function ($rows) {
        foreach ($rows as $row) {
            echo $row['field_two'] . "\n";
        }
    });

Buffer engine for insert queries See https://clickhouse.tech/docs/en/engines/table-engines/special/buffer/

<?php

namespace App\Models\Clickhouse;

use Tang\HyperfClickhouse\Model;

class MyTable extends Model
{
    // Not necessary. Can be obtained from class name MyTable => my_table
    protected $table = 'my_table';
    // All inserts will be in the table $tableForInserts 
    // But all selects will be from $table
    protected $tableForInserts = 'my_table_buffer';
}

If you also want to read from your buffer table, put its name in $table

<?php

namespace App\Models\Clickhouse;

use Tang\HyperfClickhouse\Model;

class MyTable extends Model
{
    protected $table = 'my_table_buffer';
}

OPTIMIZE Statement See https://clickhouse.com/docs/ru/sql-reference/statements/optimize/

MyTable::query()->optimize($final = false, $partition = null);

Deletions

See https://clickhouse.com/docs/en/sql-reference/statements/alter/delete/

MyTable::query()->where('field_one', 123)->delete();

Using buffer engine and performing OPTIMIZE or ALTER TABLE DELETE

<?php

namespace App\Models\Clickhouse;

use Tang\HyperfClickhouse\Model;

class MyTable extends Model
{
    // All SELECT's and INSERT's on $table
    protected $table = 'my_table_buffer';
    // OPTIMIZE and DELETE on $tableSources
    protected $tableSources = 'my_table';
}
