Using Amazon Athena Federated Query
Unless your organization is special, you are storing data in a wide variety of storage types and often selecting the storage type on a "fit for purpose" basis. In other words, you are selecting graph databases when they make sense, relational databases when appropriate, and S3 object storage or Hadoop HDFS when it makes the most sense. For example, Amazon Neptune (a graph database) may be the best choice if you are building a social network application. Or, if you are building an application that requires a flexible schema, Amazon Dynamo DB may be a solid choice. AWS offers many different types of persistence solutions, such as these:

- Time-series database services
