You can create a table with the Management Console, CloudFormation, SDKs, or the CLI. Items in a table are not required to have the same attributes, there is no enforced schema. The attribute value can be scalar (number, string, binary, boolean), multi-valued (number set, string set, binary set) or JSON document (object, array). Table, item, attributeĪ DynamoDB table has a name and organizes a collection of items. You will now have a look at these basic building blocks of DynamoDB. A table can also maintain secondary indexes for data lookup besides the primary key. Each table contains items (values) that are identified by keys. So there is no need for a backup from a durability point of view - the backup is already inside the database.ĭynamoDB is made for developers! Using DynamoDBĭynamoDB is a key-value store that organizes your data in tables.

This also means that you must not care about updating your database.

Therefore you really can’t install DynamoDB like you install MySQL or MongoDB. Instead it is a NoSQL database as a Service. DynamoDB is not a software you can download.You don’t need to worry about installation, updates, servers, storage or backups.

That having been said, this article is going to look how to use DynamoDB - both how to administer it like any other service but also how to program your applications to use it. You can scale from one item to billions and from one request per second to tens of thousands of requests per second. DynamoDB is highly available and highly durable. Unlike Relational Database Service (RDS) which is effectively providing several common RDBMS engines like MySQL, Oracle Database, Microsoft SQL Server and PostgreSQL, DynamoDB is a fully managed, proprietary, closed source key-value store.

We call them NoSQL databases.Īmazon provides a NoSQL database service called DynamoDB. The way to tackle this has been to use databases which don’t adhere to these guarantees. The more nodes you add, the slower your database gets, because more and more nodes must coordinate transactions between each other. Scaling a traditional, relational database is very hard because transactional guarantees (Atomicity, Consistency, Isolation, Durability also known as ACID) require communication between all nodes of the database.
