Time series are a very common data format that describes how things change over time. Some of the most common sources are industrial machines and IoT devices, IT infrastructure stacks (such as hardware, software, and networking components), and applications that share their results over time. Managing time series data efficiently is not easy because the data model doesn’t fit general-purpose databases.

For this reason, I am happy to share that Amazon Timestream is now generally available. Timestream is a fast, scalable, and serverless time series database service that makes it easy to collect, store, and process trillions of time series events per day up to 1,000 times faster and at as little as to 1/10th the cost of a relational database.

This is made possible by the way Timestream is managing data: recent data is kept in memory and historical data is moved to cost-optimized storage based on a retention policy you define. All data is always automatically replicated across multiple availability zones (AZ) in the same AWS region. New data is written to the memory store, where data is replicated across three AZs before returning success of the operation. Data replication is quorum based such that the loss of nodes, or an entire AZ, does not disrupt durability or availability. In addition, data in the memory store is continuously backed up to Amazon Simple Storage Service (S3) as an extra precaution.

Queries automatically access and combine recent and historical data across tiers without the need to specify the storage location, and support time series-specific functionalities to help you identify trends and patterns in data in near real time.

There are no upfront costs, you pay only for the data you write, store, or query. Based on the load, Timestream automatically scales up or down to adjust capacity, without the need to manage the underlying infrastructure.

Timestream integrates with popular services for data collection, visualization, and machine learning, making it easy to use with existing and new applications. For example, you can ingest data directly from AWS IoT Core, Amazon Kinesis Data Analytics for Apache Flink, and Amazon MSK. You can visualize data stored in Timestream from Amazon QuickSight, and use Amazon SageMaker to apply machine learning algorithms to time series data, for example for anomaly detection. You can use Timestream fine-grained AWS Identity and Access Management (IAM) permissions to easily ingest or query data from an AWS Lambda function. We are providing the tools to use Timestream with open source platforms such as Apache Kafka, Telegraf, Prometheus, and Grafana.

Using Amazon Timestream from the Console

In the Timestream console, I select Create database. I can choose to create a Standard database or a Sample database populated with sample data. I proceed with a standard database and I name it MyDatabase.
