## Installation

You can install the package via composer:

```bash
composer require orptech/laravel-migration-partition
```

## DBMS Support

- PostgreSQL

### Planned Development

- MySQL - Looking for Contributors
- MariaDB - Looking for Contributors
- SQL Server 2017+
- SQLite 3.8.8+

## Usage
This package currently, only supports PostgreSQL.

## PostgreSQL
PostgreSQL also known as Postgres, is a free and open-source relational database management system (RDBMS) emphasizing extensibility and SQL compliance.

### Range Partitioning
Instead of importing Illuminate's Schema import this package's schema:
```php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
```

## Template Usage

### Range Partition

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::createRangePartitioned('[YourTableNameHere]', function (Blueprint $table) {
//...
}, '[compositeKeyOne]', '[compositeKeyTwo]', '[rangePartitionKey]');
```

##### Creating a Range Partition for a Partitioned Table

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::createRangePartition('[YourPartitionedTableNameHere]', function (Blueprint $table) {}, '[suffixForPartition]', '[startDate]', '[endDate]');
```

##### Attaching a Range Partition to a Partitioned Table

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::attachRangePartition('[YourPartitionedTableNameHere]', function (Blueprint $table) {}, '[suffixForPartition]', '[startDate]', '[endDate]');
```

### List Partition

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::createListPartitioned('[YourTableNameHere]', function (Blueprint $table) {
//...
}, '[compositeKeyOne]', '[compositeKeyTwo]', '[listPartitionKey]');
```

##### Creating a List Partition for a Partitioned Table

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::createListPartition('[YourPartitionedTableNameHere]', function (Blueprint $table) {}, '[suffixForPartition]', '[listPartitionValue]');
```

##### Attaching a List Partition to a Partitioned Table

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::attachListPartition('[YourPartitionedTableNameHere]', function (Blueprint $table) {}, '[suffixForPartition]', '[listPartitionValue]');
```

### Hash Partition

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::createHashPartitioned('[YourTableNameHere]', function (Blueprint $table) {
//...
}, '[compositeKeyOne]', '[compositeKeyTwo]', '[hashPartitionKey]');
```

##### Creating a Hash Partition for a Partitioned Table

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::createHashPartition('[YourPartitionedTableNameHere]', function (Blueprint $table) {}, '[suffixForPartition]', '[hashModulus]', '[hashRemainder]');
```

##### Attaching a Hash Partition to a Partitioned Table

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::attachHashPartition('[YourPartitionedTableNameHere]', function (Blueprint $table) {}, '[suffixForPartition]', '[hashModulus]', '[hashRemainder]');
```

#### Removing a Partition

```php
use ORPTech\MigrationPartition\Database\Schema\Blueprint;
use ORPTech\MigrationPartition\Support\Facades\Schema;

Schema::detachPartition('[YourPartitionedTableNameHere]', function (Blueprint $table) {}, '[partitionTableName]');
```

## Commands

##### New Series of Range Partition Migrations
This command will create a new series of migrations for all range partitioned tables.
```bash
php artisan partition:range
```

##### New Series of List Partition Migrations
This command will create a new series of migrations for all list partitioned tables.
```bash
php artisan partition:list
```

##### New Series of Hash Partition Migrations
This command will create a new series of migrations for all hash partitioned tables.
```bash
php artisan partition:hash
```

##### Listing Partitions
This command will list all the partitioned tables.
```bash
php artisan partition:partitions
```

### Important
- This package currently supports PostgreSQL Range Partitions.
- You shouldn't define any primary keys in your migration. The package creates a composite key while setting up the table.
- You need to create an initial partition to start using the tables. (PostgreSQL)

## Testing

```bash
composer test
```
