Partition key: A simple primary key, composed of one attribute known as thepartition key. Attributes in DynamoDB are similar in many ways to fields or columns in other database systems. Partition key and sort key: Referred to as acomposite primary key, this type of key is composed of two...

What is a hotkey in DynamoDB? Hotkeys inDynamoDBfrom AWS refer to a partition key value that experiences a high volume of read-or-write requests. This often triggers uneven data distribution that will impact performance. Strategies likesharding, using composite partition keys and adjusting capac...
partition key which describes the partition in which the item will be stored. The Type is the sort key, which determines the order in which items will be stored in disk. The combination of the Partition Key and the Sort Key forms a unique primary key, which maps to a single value in ...
7. Amazon DynamoDB partitions In DynamoDB, data is partitioned automatically by its hash key. That’s why you will need to choose a hash key if you're implementing a GSI. The partitioning logic depends upon two things: table size and throughput. The partition for a table is calculated by...
Basically Available: BASE consistency ensures that the database remains available for both read and write operations, even in the presence of failures or partitions. High availability is a key feature of BASE systems. Soft state.Soft state means that the data in the system can change over time...
Amazon DynamoDB Riak Oracle NoSQL Some tabular NoSQL databases, like Cassandra, can also service key-value needs. Document databases Document databases expand on the basic idea of key-value stores where “documents” are more complex, in that they contain data and each document is assigned a ...

partitionability, key-value databases are capable of horizontal scaling at scales that other types of databases are unable to achieve. For example, if an existing partition reaches its maximum capacity and additional storage space is required, Amazon DynamoDB will allocate additional partitions to the...
A distributed key value database can be configured to store the same data in multiple nodes across locations. If a single node fails, the data is still available. You don’t have to wait for the database to be restored. A geo-distributed database maintains concurrent nodes across geographica...
