Dynamic Features of Amazon DynamoDB

Since it was first launched in 2012, Amazon DynamoDB has provided a reliable and scalable non-relational database to at least 100,000 users. Below are some of its useful features:

  • Global Tables – This feature lets users automatically duplicate tables over two or more AWS regions. It provides the option for multi-master writes, an extra redundancy layer, and a scalable rapid read/write performance. Global Table are available in nine regions: Asia Pacific (Tokyo), Asia Pacific (Seoul), Asia Pacific (Sydney), Asia Pacific (Singapore), EU (Frankfurt), EU (Ireland), US West (Oregon), US East (Ohio), and US East (N. Virginia).
  • Encryption – DynamoDB protects the data you store in it with encryption at rest. It uses AES-256 to encrypt data stored in tables, local secondary indexes, and global secondary indexes. This encryption is transparent, does not add to storage, and does it affect latency.
  • Point-In-Time Recovery – This feature allows you to restore the database to a point in time within 35 days before. All you need to do is enable continuous backup to create restoration points.
  • Service-level Agreement – 99.999% guaranteed availability in a single region and for global tables.
  • Adaptive Capacity – In case uneven distribution of data across storage partitions, Amazon DynamoDB allots one partition more than its usual share of space for the necessary period of time, so long as it is within the total provisioned capacity.
