AWS Timestream, a time series database introduced by Amazon Web Services, is designed for high-performance, cost-effective processing of time-series data, offering features like automatic scaling, built-in analytics, and automatic data lifecycle management. It supports SQL queries with functions for data smoothing and interpolation, making it suitable for monitoring system health metrics and other time-series data. Timestream, being serverless, simplifies data management by automatically handling capacity and encryption, and it utilizes two tiers of memory storage for efficient data access. While it excels in time-series data analysis compared to AWS's other relational and key-value databases, Timestream's append-only nature means data cannot be updated or deleted once entered. Its capacity to handle vast amounts of data daily and its ability to integrate with external analysis tools like Coralogix for deeper insights make it a robust solution for system health monitoring and other time-based data tracking needs.
