Overview of Amazon Timestream

Amazon Timestream is a time-series database. A time-series database is optimized for storing and querying data saved in key pairs of time and value. It is often used when data is being stored from sensors or operations with a timestamp and associated value that need to be tracked for trending analysis.

Timestream is a fully-managed, serverless, and scalable database service specifically customized and optimized for Internet of Things (IOT) devices and application sensors, allowing you to store trillions of events per day up to 1,000 times faster than via an RDBMS. Being serverless means you do not need to define your compute values, as Timestream will automatically scale up and down depending on the current workload.
