This creates a table on DynamoDB and can be used to store data once active.
Update table
Updating a table in DynamoDB is quite easy; you just need to specify the table name and
the specifications that need to be updated. DynamoDB allows us to only update provision

$dynamodbclient->updateTable(array(
"TableName" => $tableName,
"ProvisionedThroughput" => array(
"ReadCapacityUnits" => 30,
"WriteCapacityUnits" => 30
)
));
Here we are updating the read and write capacity units to 30 for the table Book .
Delete table
Deleting a table in DynamoDB is quite easy; you just need to mention the name of the
table to be deleted and invoke the deleteTable method. You should be careful while

$tableName = "Book";
$result = $dynamodbclient->deleteTable(array(
"TableName" => $tableName
));
List tables
The DynamoDB SDK allows us to list down all available tables for a given account by in-
voking the listtable method from the DynamoDB client. You can optionally mention
whether you want to limit the result to a specific number. You can also mention whether
