Adapter to Laravel of the most popular libraries:

Features

No dependency, only Curl (support php >=7.1 )

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

Prerequisites

  • php 7.1
  • Laravel 7+
  • clickhouse server

Installation

1. Install via composer

$ composer require glushkovds/phpclickhouse-laravel

2. 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',''),
    'timeout_connect' => env('CLICKHOUSE_TIMEOUT_CONNECT',2),
    'timeout_query' => env('CLICKHOUSE_TIMEOUT_QUERY',2),
    'https' => (bool)env('CLICKHOUSE_HTTPS', null),
    'retries' => env('CLICKHOUSE_RETRIES', 0),
],

Then patch your .env:

CLICKHOUSE_HOST=localhost
CLICKHOUSE_PORT=8123
CLICKHOUSE_DATABASE=default
CLICKHOUSE_USERNAME=default
CLICKHOUSE_PASSWORD=
CLICKHOUSE_TIMEOUT_CONNECT=2
CLICKHOUSE_TIMEOUT_QUERY=2
# only if you use https connection
CLICKHOUSE_HTTPS=true

3. Add service provider into your config/app.php file providers section:

\PhpClickHouseLaravel\ClickhouseServiceProvider::class,

Usage

You can use smi2/phpClickHouse functionality directly:

/** @var \ClickHouseDB\Client $db */
$db = DB::connection('clickhouse')->getClient();
$statement = $db->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 PhpClickHouseLaravel\BaseModel;

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

}

2. Add migration

<?php


class CreateMyTable extends \PhpClickHouseLaravel\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');
    }
}

3. And then you can insert data

One row

$model = MyTable::create(['model_name' => 'model 1', 'some_param' => 1]);
# or
$model = MyTable::make(['model_name' => 'model 1']);
$model->some_param = 1;
$model->save();
# or
$model = new MyTable();
$model->fill(['model_name' => 'model 1', 'some_param' => 1])->save();

Or bulk insert

# Non assoc way
MyTable::insertBulk([['model 1', 1], ['model 2', 2]], ['model_name', 'some_param']);
# Assoc way
MyTable::insertAssoc([['model_name' => 'model 1', 'some_param' => 1], ['some_param' => 2, 'model_name' => 'model 2']]);

4. Now check out the query builder

$rows = MyTable::select(['field_one', new RawColumn('sum(field_two)', 'field_two_sum')])
    ->where('created_at', '>', '2020-09-14 12:47:29')
    ->groupBy('field_one')
    ->getRows();

Advanced usage

Retries

You may enable ability to retry requests while received not 200 response, maybe due network connectivity problems.

Patch your .env:

CLICKHOUSE_RETRIES=2

retries is optional, default value is 0.
0 mean only one attempt.
1 mean one attempt + 1 retry while error (total 2 attempts).
