Supports all key types - primary hash key and composite keys.
For advanced users only. If you're not familiar with Laravel, Laravel Eloquent and DynamoDB, then I suggest that you get familiar with those first.

Composer install
composer require baopham/dynamodb
-
Install service provider (< Laravel 5.5):
// config/app.php 'providers' => [ ... BaoPham\DynamoDb\DynamoDbServiceProvider::class, ... ];
-
Run
php artisan vendor:publish --provider 'BaoPham\DynamoDb\DynamoDbServiceProvider' -
Update DynamoDb config in config/dynamodb.php
For Lumen
-
Try this to install the
vendor:publishcommand -
Load configuration file and enable Eloquent support in
bootstrap/app.php:$app = new Laravel\Lumen\Application( realpath(__DIR__.'/../') ); // Load dynamodb config file $app->configure('dynamodb'); // Enable Facade support $app->withFacades(); // Enable Eloquent support $app->withEloquent();
- Extends your model with
BaoPham\DynamoDb\DynamoDbModel, then you can use Eloquent methods that are supported. The idea here is that you can switch back to Eloquent without changing your queries. - Or if you want to sync your DB table with a DynamoDb table, use trait
BaoPham\DynamoDb\ModelTrait, it will call aPutItemafter the model is saved. - Alternatively, you can use the query builder facade to build more complex queries.
- AWS SDK v3 for PHP uses guzzlehttp promises to allow for asynchronous workflows. Using this package you can run eloquent queries like delete, update, save asynchronously on DynamoDb.
$model->find($id, array $columns = []);
$model->findMany($ids, array $columns = []);
$model->delete();
$model->deleteAsync()->wait();// Using getIterator()
// If 'key' is the primary key or a global/local index and it is a supported Query condition,
// will use 'Query', otherwise 'Scan'.
$model->where('key', 'key value')->get();
$model->where(['key' => 'key value']);
// Chainable for 'AND'.
$model->where('foo', 'bar')
->where('foo2', '!=', 'bar2')
->get();
// Chainable for 'OR'.
$model->where('foo', 'bar')

// Other types of conditions

// Nested attributes
$model->where('nestedMap.foo', 'bar')->where('list[0]', 'baz')->get();NULL and NOT_NULL only check for the attribute presence not its value being null
See: http://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_Condition.html
$model->whereNull('name');
$model->whereNotNull('name');// Using scan operator, not too reliable since DynamoDb will only give 1MB total of data.
$model->all();
// Basically a scan but with limit of 1 item.
$model->first();Unfortunately, offset of how many records to skip does not make sense for DynamoDb. Instead, provide the last result of the previous query as the starting point for the next query.
Examples:
For query such as:
$query = $model->where('count', 10)->limit(2);
$items = $query->all();
$last = $items->last();Take the last item of this query result as the next "offset":
$nextPage = $query->after($last)->limit(2)->all();
// or
$nextPage = $query->afterKey($items->lastKey())->limit(2)->all();
// or (for query without index condition only)
$nextPage = $query->afterKey($last->getKeys())->limit(2)->all();// update
$model->update($attributes);// update asynchronously and wait on the promise for completion.
$model->updateAsync($attributes)->wait();$model = new Model();
// Define fillable attributes in your Model class.
$model->fillableAttr1 = 'foo';
$model->fillableAttr2 = 'foo';
// DynamoDb doesn't support incremented Id, so you need to use UUID for the primary key.
$model->id = 'de305d54-75b4-431b-adb2-eb6b9e546014';
$model->save();Saving single model asynchronously and waiting on the promise for completion.
$model = new Model();
// Define fillable attributes in your Model class.
$model->fillableAttr1 = 'foo';
$model->fillableAttr2 = 'bar';
// DynamoDb doesn't support incremented Id, so you need to use UUID for the primary key.
$model->id = 'de305d54-75b4-431b-adb2-eb6b9e546014';
$model->saveAsync()->wait();Saving multiple models asynchronously and waiting on all of them simultaneously.
for($i = 0; $i < 10; $i++){

$model->fillableAttr2 = 'bar';

$model->where('id', 'foo')->removeAttribute('name', 'description', 'nested.foo', 'nestedArray[0]');
// Or
Model::find('foo')->removeAttribute('name', 'description', 'nested.foo', 'nestedArray[0]');For debugging purposes, you can choose to convert to the actual DynamoDb query
$raw = $model->where('count', '>', 10)->toDynamoDbQuery();
// $op is either "Scan" or "Query"
$op = $raw->op;
// The query body being sent to AWS
$query = $raw->query;where $raw is an instance of RawDynamoDbQuery
Use decorate when you want to enhance the query. For example:
To set the order of the sort key:
$items = $model
->where('hash', 'hash-value')
->where('range', '>', 10)
->decorate(function (RawDynamoDbQuery $raw) {
// desc order
$raw->query['ScanIndexForward'] = false;
})
->get();To force to use "Query" instead of "Scan" if the library fails to detect the correct operation:
$items = $model
->where('hash', 'hash-value')
->decorate(function (RawDynamoDbQuery $raw) {
$raw->op = 'Query';
})
->get();If your table has indexes, make sure to declare them in your model class like so
/**
* Indexes.
* [
* '<simple_index_name>' => [
* 'hash' => '<index_key>'
* ],
* '<composite_index_name>' => [
* 'hash' => '<index_hash_key>',
* 'range' => '<index_range_key>'
* ],
* ]
*
* @var array
*/
protected $dynamoDbIndexKeys = [
'count_index' => [
'hash' => 'count'
],
];Note that order of index matters when a key exists in multiple indexes.
For example, we have this
$model->where('user_id', 123)->where('count', '>', 10)->get();with
protected $dynamoDbIndexKeys = [
'count_index' => [
'hash' => 'user_id',
'range' => 'count'
],
'user_index' => [
'hash' => 'user_id',
],
];will use count_index.
protected $dynamoDbIndexKeys = [
'user_index' => [
'hash' => 'user_id',
],
'count_index' => [
'hash' => 'user_id',
'range' => 'count'
]
];will use user_index.
Most of the time, you should not have to do anything but if you need to use a specific index, you can specify it like so
$model->where('user_id', 123)->where('count', '>', 10)->withIndex('count_index')->get();To use composite keys with your model:
- Set
$compositeKeyto an array of the attributes names comprising the key, e.g.
protected $primaryKey = 'customer_id';
protected $compositeKey = ['customer_id', 'agent_id'];- To find a record with a composite key
$model->find(['customer_id' => 'value1', 'agent_id' => 'value2']);Use DynamoDb facade to build raw queries
use BaoPham\DynamoDb\Facades\DynamoDb;
DynamoDb::table('articles')
// call set<key_name> to build the query body to be sent to AWS
->setFilterExpression('#name = :name')
->setExpressionAttributeNames(['#name' => 'author_name'])
->setExpressionAttributeValues([':name' => DynamoDb::marshalValue('Bao')])
->prepare()
// the query body will be sent upon calling this.
->scan(); // supports any DynamoDbClient methods (e.g. batchWriteItem, batchGetItem, etc.)
DynamoDb::table('articles')
->setIndexName('author_name')
->setKeyConditionExpression('#name = :name')
->setProjectionExpression('id, author_name')
// Can set the attribute mapping one by one instead
->setExpressionAttributeName('#name', 'author_name')
->setExpressionAttributeValue(':name', DynamoDb::marshalValue('Bao'))
->prepare()
->query();
DynamoDb::table('articles')
->setKey(DynamoDb::marshalItem(['id' => 'ae025ed8']))
->setUpdateExpression('REMOVE #c, #t')
->setExpressionAttributeName('#c', 'comments')
->setExpressionAttributeName('#t', 'tags')
->prepare()
->updateItem();
DynamoDb::table('articles')
->setKey(DynamoDb::marshalItem(['id' => 'ae025ed8']))
->prepare()
->deleteItem();
DynamoDb::table('articles')
->setItem(DynamoDb::marshalItem(['id' => 'ae025ed8', 'author_name' => 'New Name']))
->prepare()
->putItem();
// Or, instead of ::table()
DynamoDb::newQuery()
->setTableName('articles')
// Or access the DynamoDbClient instance directly
DynamoDb::client();
// pass in the connection name to get a different client instance other than the default.
DynamoDb::client('test');The query builder methods are in the form of set<key_name>, where <key_name> is the key name of the query body to be sent.
For example, to build an UpdateTable query:
[
'AttributeDefinitions' => ...,
'GlobalSecondaryIndexUpdates' => ...,
'TableName' => ...
]Do:
$query = DynamoDb::table('articles')
->setAttributeDefinitions(...)
->setGlobalSecondaryIndexUpdates(...);And when ready:
$query->prepare()->updateTable();Laravel ^5.1

- Update your
composer.jsonto use v2 - Run
composer update - Run
php artisan vendor:publish - Move your DynamoDb config in
