InfluxDB

InfluxDB stores and queries time-stamped data with high write and read throughput. It uses a SQL-like query language called Flux (and InfluxQL) to aggregate, downsample, and analyze metrics. The database supports automatic retention policies, continuous queries, and data compression to manage storage costs. It integrates natively with Telegraf for data collection and Grafana for visualization, making it a common backend for monitoring stacks. InfluxDB runs on Linux, Windows, macOS, and as a cloud service. The open source version (MIT license) includes core functionality, while InfluxDB Cloud and Enterprise add clustering, high availability, and advanced security features. InfluxData, the company behind the project, also offers a managed cloud platform with automatic scaling. The latest stable release is 2.7.6, which introduced improved memory management and enhanced Flux performance. For developers building IoT or observability pipelines, InfluxDB provides client libraries for Go, Python, Java, and other languages. Its ability to handle millions of data points per second makes it a practical choice for DevOps teams and sensor networks.
