Laravel database driver for TiDB

Requirements

• PHP >= 7.4
• Laravel 6 ~ 10
• TiDB >= 4.0

Installation

Install via composer

composer require colopl/laravel-tidb

That's all. You can use database connection as usual.

Features

• Added autoRandom($shard_bits = null) to ColumnDefinition
• When user defines $table->id() in the migration file, it will add PRIMARY KEY AUTO_RANDOM to the schema instead of PRIMARY KEY AUTO_INCREMENT so that data gets distributed evenly.
• Added Support for nested transactions (MySQL driver will throw an exception)
• Added Support for adding/dropping multiple columns (MySQL driver will throw an exception)

Unsupported features

1. Nesting transactions and then rolling them back will always rollback to the first transaction since SAVEPOINT is not supported by TiDB. In other words, rolling back with $connection->rollBack() will always rollback level to 0.
2. Adding and dropping multiple columns atomically is not fully supported. Defining multiple columns in migrations is supported but will be executed one by one and will not be atomic. Ex: $table->dropColumn('title', 'content')

For unsupported features for TiDB itself, please see MySQL Compatibility.

Testing

You can run tests on docker by the following command.

make test
