README

Easily use DynamoDB as a cache, session, or queue using this library in your Yii2 or Craft CMS projects.

Note: currently Craft supports Yii2 Queue version 2.3.0 so this package is based on version 2.3.0 of yii2-queue.

Installation

You can install the package via composer:

composer require craftcms/yii2-dynamodb

Usage

This package provides three Yii components for DynamoDB: cache, session, and queue.

Cache Component

Create DynamoDB Cache Table

Since DynamoDB is a NoSQL database, the only key you have to specify is the primary key. You can use the following AWS CLI command to generate a table for the cache.

aws dynamodb create-table --table-name=my-app-cache-table \
    --attribute-definitions=AttributeName=id,AttributeType=S \
    --key-schema=AttributeName=id,KeyType=HASH \
    --billing-mode=PAY_PER_REQUEST

Note: Since the ID can contain more than numbers, it needs to be specified as a string in DynamoDB.

Configure Cache Component

In your app.php, configure the cache component to use the driver.

use craftcms\dynamodb\DynamoDbCache;

return [
    'bootstrap' => [
        'cache',
    ],
    'components' => [
        'cache' => [
            'class' => DynamoDbCache::class,
            'dataAttribute' => 'data', // optional: defaults to data
            'dynamoDb' => [
                'table' => 'my-app-cache-table',
                'partitionKeyAttribute' => 'id', // optional: defaults to 'PK'
                'endpoint' => 'http://localhost:8000', // optional: used for local or when using DAX
                'region' => '<region>', // optional: defaults to AWS_REGION env var
                'ttl' => 60*60*24, // optional: number of seconds until items are considered expired
                'ttlAttribute' => 'expires' // optional: defaults to 'TTL'
                'credentials' => [
                    'key' => '<key>', // optional: defaults to AWS_ACCESS_KEY_ID env var
                    'secret' => '<secret>', // optional: defaults to AWS_SECRET_ACCESS_KEY env var
                ],
            ],
        ],
    ],
];

Session Component

Create DynamoDB Session Table

Since DynamoDB is a NoSQL database, the only key you have to specify is the primary key. You can use the following AWS CLI command to generate a table for the session.

aws dynamodb create-table --table-name=my-app-session-table \
    --attribute-definitions=AttributeName=id,AttributeType=S \
    --key-schema=AttributeName=id,KeyType=HASH \
    --billing-mode=PAY_PER_REQUEST

Note: Since the ID can contain more than numbers, it needs to be specified as a string in DynamoDB.

Configure Session Component

In your app.php, configure the session component to use the driver.

use craftcms\dynamodb\DynamoDbSession;

return [
    'bootstrap' => [
        'session',
    ],
    'components' => [
        'session' => [
            'class' => DynamoDbSession::class,
            'dataAttribute' => 'data', // optional: defaults to data
            'dynamoDb' => [
                'table' => 'my-app-session-table',
                'partitionKeyAttribute' => 'id', // optional: defaults to 'PK'
                'endpoint' => 'http://localhost:8000', // optional: used for local or when using DAX
                'region' => '<region>', // optional: defaults to AWS_REGION env var
                'ttl' => 60*60*24, // optional: number of seconds until items are considered expired
                'ttlAttribute' => 'expires' // optional: defaults to 'TTL'
                'credentials' => [
                    'key' => '<key>', // optional: defaults to AWS_ACCESS_KEY_ID env var
                    'secret' => '<secret>', // optional: defaults to AWS_SECRET_ACCESS_KEY env var
                ],
            ],
        ],
    ],
];

Queue Component

Create DynamoDB Queue Table

Since DynamoDB is a NoSQL database, the only key you have to specify is the primary key. You can use the following AWS CLI command to generate a table for the queue.

aws dynamodb create-table --table-name=my-app-queue-table \
    --attribute-definitions=AttributeName=id,AttributeType=S \
    --key-schema=AttributeName=id,KeyType=HASH \
    --billing-mode=PAY_PER_REQUEST

Note: Since the ID can contain more than numbers, it needs to be specified as a string in DynamoDB.

Configure Queue Component

In your app.php, configure the queue component to use the driver.

use craftcms\dynamodb\DynamoDbQueue;

return [
    'bootstrap' => [
        'queue',
    ],
    'components' => [
        'queue' => [
            'class' => DynamoDbQueue::class,
            'dynamoDb' => [
                'table' => 'my-app-queue-table',
                'partitionKeyAttribute' => 'id', // optional: defaults to 'PK'
                'endpoint' => 'http://localhost:8000', // optional: used for local or when using DAX
                'region' => '<region>', // optional: defaults to AWS_REGION env var
                'ttl' => 60*60*24, // optional: number of seconds until items are considered expired
                'ttlAttribute' => 'expires' // optional: defaults to 'TTL'
                'credentials' => [
                    'key' => '<key>', // optional: defaults to AWS_ACCESS_KEY_ID env var
                    'secret' => '<secret>', // optional: defaults to AWS_SECRET_ACCESS_KEY env var
                ],
            ],
        ],
    ],
];

Testing

Tests run against local DynamoDB tables using Docker. To run tests, you must run the following:

1. Ensure Docker is running
2. Start the DynamoDB container in the docker-compose.yaml with docker-compose up -d
3. Create the DynamoDB tables for the cache, session, and queue
4. Run the test suite with vendor/bin/phpunit --testdox

To make the setup and testing easier, you can run the following Composer scripts:

1. composer run setup
2. composer run test
