README

This bundle added the migrations system for clickhouse type Databases into Symfony applications. Database migrations help you version the changes in your database schema and apply them in a predictable way on every server running the application.

Install

composer require dmamontov/clickhouse-migrations-bundle

Clickhouse connection

For use this bundle you need set clickhouse Client as Symfony service. As example:

#config/services.yaml
services:
    ClickHouseDB\Client:
        arguments:
            $connectParams:
                host: 'http://localhost'
                port: 8123
                username: 'username'
                password: ''
                sslCA: 'path_to_ssl_cert'
            $settings:
                database: 'default'

More details about ClickHouseDB\Client settings.

    table_name: 'migrations_versions'
    migrations_path: '%kernel.project_dir%/clickhouse_migrations'
    migrations_namespace: 'ClickhouseMigrations'
