Installation guide

If you have a large array of items you wish to add to your table, you could iterate over the them, add each item to the

batch object. After all the items are added call flush(). The batch object will automatically flush the batch and

write items to Amazon DynamoDB after hitting a customizable threshold. A final call to the batch object's flush()

method is necessary to transfer any remaining items in the queue.

$tableName = 'batch-write-test'; // This table has a HashKey named "id"

$itemIds = array();

// Put 55 items into the table

$putBatch = WriteRequestBatch::factory($client);

for ($i = 0; $i < 55; $i++) {

$itemIds[] = $itemId = uniqid();

$item = Item::fromArray(array(

'id' => $itemId,

'timestamp' => time(),

));

$putBatch->add(new PutRequest($item, $tableName));

}

$putBatch->flush();

You can also use the WriteRequestBatch object to delete items in batches.

// Remove items from the table

$deleteBatch = WriteRequestBatch::factory($client);

foreach ($itemIds as $itemId) {

$key = array('HashKeyElement' => array('S' => $itemId));

$deleteBatch->add(new DeleteRequest($key, $tableName));

}

$deleteBatch->flush();

The WriteRequestBatch, PutRequest, and DeleteRequest classes are all a part of the

Aws\DynamoDb\Model\BatchRequest namespace.
