DynamoDB lets you offload the administrative burdens of operating and scaling a distributed database so that you don't have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling. DynamoDB also offers encryption at rest, which eliminates the operational burden and complexity involved in protecting sensitive data. With DynamoDB, you can create database tables that can store and retrieve any amount of data and serve any level of request traffic.
You can scale up or scale down your tables' throughput capacity without downtime or performance degradation. DynamoDB provides on-demand backup capability. It allows you to create full backups of your tables for long-term retention and archival for regulatory compliance needs. You can create on-demand backups and enable point-in-time recovery for your Amazon DynamoDB tables.
Point-in-time recovery helps protect your tables from accidental write or delete operations. With point-in-time recovery, you can restore that table to any point in time during the last 35 days. DynamoDB allows you to delete expired items from tables automatically to help you reduce storage usage and the cost of storing data that is no longer relevant.
DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is stored on solid-state disks SSDs and is automatically replicated across multiple Availability Zones in an AWS Region, providing built-in high availability and data durability.

Thanks for letting us know this page needs work. We're sorry we let you down. If you've got a moment, please tell us how we can make the documentation better.
NoSQL Workbench is a unified visual tool that provides data modeling, data visualization, and query development features to help you design, create, query, and manage DynamoDB tables. With NoSQL Workbench for DynamoDB, you can build new data models from, or design models based on, existing data models that satisfy your application's data access patterns. You can also import and export the designed data model at the end of the process. The data model visualizer provides a canvas where you can map queries and visualize the access patterns facets of the application without having to write code.
Every facet corresponds to a different access pattern in DynamoDB. You can manually add data to your data model or import data from MySQL.
For more information, see Visualizing Data Access Patterns. NoSQL Workbench provides a rich graphical user interface for you to develop and test queries. You can use the operation builder to view, explore, and query datasets. You can also use the structured operation builder to build and perform data plane operations.

Reference Materials A set of links and reference materials describing how DynamoDB works and best practices for building data models.DynamoDB is one of the fastest-growing databases right now.
It's fully-managed, has pay-per-use billing, and fits perfectly with serverless compute. But modeling your data in DynamoDB is significantly different than modeling in a traditional relational database. And if you try to model your DynamoDB table like your relational database, you'll be in a world of hurt. In this post, we're going to cover my top ten tips for data modeling with DynamoDB. They run the gamut, from understanding of basic principles to concrete design tips to billing advice.
With these tips, you'll be on your way to DynamoDB success. If you find yourself enjoying this content as you go, I'd really appreciate and encourage you to take a look at my new book on DynamoDB as well! By far, the biggest mindset shift you will make as you move from a traditional relational database into DynamoDB is the acceptance of "single-table design". In a relational database, each different entity will receive its own table, specifically shaped to hold that entity's data.
There will be columns for each of the entity's attributes with required values and constraints. With DynamoDB, this isn't the case.AWS re:Invent 2014: From Zero to NoSQL Hero - Amazon DynamoDB Tutorial (BDT203)
You'll jam all of your entities--Customers, Orders, Inventory, etc. There are no required columns and attributes, save for the primary key which uniquely identifies each item. Take some time to understand why you need single-table design in DynamoDB. Single-table design is about efficiently organizing your data in the shape needed by your access patterns to quickly and efficiently use your data.
You won't have the neat, tidy, spreadsheet-like data that you had with a relational database. In fact, your table will look "more like machine code than a simple spreadsheet". But you will have a database that will scale to massive levels without any performance degradation. Quote text: "If you don't know where you are going, any road will get you there. With single-table design, you design your table to handle your access patterns. This implies that you must know your access patterns before you design.
So many developers want to design their DynamoDB table before they know how they'll use it. But again, this is that relational database mindset creeping into your process.
With a relational database, you design your tables first, then add the indexes and write the queries to get the data you need. With DynamoDB, you first ask how you want to access the data, then build the table to handle these patterns. This requires thoughtful work upfront. It requires engaging with PMs and business analysts to fully understand your application.
And while this seems like it slows you down, you'll be glad you've done the work when you don't have to think about scaling your database when your application grows. As developers, it's hard not to jump straight into the code. There's nothing quite like the dopamine hit of making something from nothing; from saying, "Yes, I built that! But you need to resist that impulse in DynamoDB.
Once you've outlined your access patterns, then take the time to model your DynamoDB table. This should be done outside of your code. In this case, I just use a spreadsheet to list each entity type and the primary key pattern for each entity.
I have additional pages for any secondary indexes in my table. Once you complete these artifacts, then you can move into implementation. These artifacts will serve as great additions to your service documentation. When learning relational data modeling, we heard all about normalization.
Don't repeat data in multiple places.To add a new connection, right-click the Connection Manager area in your Visual Studio project, and choose "New Connection The Server page allows you to specify connection properties and login credentials to Amazon DynamoDB.
The AWS Region drop-down list allows you to pick the endpoint based on your region. To find your Access Key follow these instructions:. Note that the secret key can only be retrieved when creating the key, which means if you forget the secret key you can only create a new access key in Amazon DynamoDB.
The Session Token option allows you to specify a temporary security token, known as temporary security credentials. After all the connection information has been provided, you may click the "Test Connection" button to test if you can connect successfully. The Connection Timeout option allows you to specify the number of seconds for the request timeout values. The default value is 30 seconds.
The default value is 60 seconds. The Max Error Retry Count option allows you to specify the number of retries at service client level. By setting this property, the component will retry the operation the specified number of times before failing and throwing an exception. The default value is 3.
What Is Amazon DynamoDB?
Proxy Mode option allows to specify how you want to configure the proxy server settings. There are three options available. The Port option allows you to specify the port number of the proxy server for the connection.
This is done by design for security reasons. However you can include it in your ConnectionString if you want to parameterize your connection manager. It can be anywhere in the ConnectionString.

NoSQL Workbench for Amazon DynamoDB – Available in Preview
In the navigation pane, choose Users.Amazon DynamoDB is a fully managed proprietary NoSQL database service that supports key-value and document data structures  and is offered by Amazon. Dynamo had a multi-master design requiring the client to resolve version conflicts and DynamoDB uses synchronous replication across multiple data centers  for high durability and availability.
Vogels motivates the project in his announcement. Originally, services had direct access to each other's databases. When this became a bottleneck on engineering operations, services moved away from this direct access pattern in favor of public-facing API s.
Still, third-party relational database management systems struggled to handle Amazon's client base. This culminated during the holiday season, when several technologies failed under high traffic. Engineers were normalizing these relational systems to reduce data redundancya design that optimizes for storage.
The sacrifice: they stored a given "item" of data e. Many of Amazon's services demanded mostly primary-key reads on their data, and with speed a top priority, putting these pieces together was extremely taxing.
Content with compromising storage efficiency, Amazon's response was Dynamo : a highly available key-value store built for internal use.
Amazon's developers opted for "just works" design patterns with S3 and SimpleDB. While these systems had noticeable design flaws, they did not demand the overhead of provisioning hardware and scaling and re-partitioning data. DynamoDB differs from other Amazon services by allowing developers to purchase a service based on throughputrather than storage. If Auto Scaling is enabled, then the database will scale automatically.
A DynamoDB table features items that have attributes, some of which form a primary key. The only exception: when creating a table, a developer specifies a primary key, and the table requires a key for every item.
Primary keys must be scalar stringsnumbers, or binary and can take one of two forms. A single-attribute primary key is known as the table's "partition key", which determines the partition that an item hashes to——more on partitioning below——so an ideal partition key has a uniform distribution over its range. A primary key can also feature a second attribute, which DynamoDB calls the table's "sort key".
In this case, partition keys do not have to be unique; they are paired with sort keys to make a unique identifier for each item. The partition key is still used to determine which partition the item is stored in, but within each partition, items are sorted by the sort key.
In the relational model, indices typically serve as "helper" data structures to supplement a table. They allow the DBMS to optimize queries under the hood and they do not improve query functionality. In DynamoDB, there is no query optimizerand an index is simply another table with a different key or two that sits beside the original.
DynamoDB users issue queries directly to their indices. There are two types of indices available. A global secondary index features a partition key and optional sort key that's different from the original table's partition key. A local secondary index features the same partition key as the original table, but a different sort key.
Both indices introduce entirely new query functionality to a DynamoDB database by allowing queries on new keys. Put requests contain the TableName attribute and an Item attribute, which consists of all the attributes and values the item has. An Update request follows the same syntax. Similarly, to get or delete an item, simply specify a TableName and Key. DynamoDB uses hashing and B-trees to manage data.
Upon entry, data is first distributed into different partitions by hashing on the partition key.
To prevent data loss, DynamoDB features a two-tier backup system of replication and long-term storage.
