InfluxDB

InfluxDB is the world's most widely deployed purpose-built time-series database platform, designed and optimized for the high ingestion rates, time-based queries, and data retention policies that characterize metrics, monitoring, IoT sensor data, and real-time analytics workloads. Developed by InfluxData and first released in 2013, InfluxDB powers monitoring and observability stacks for thousands of organizations worldwide, from individual developers to large-scale enterprises.

InfluxDB's data model is built around measurements (similar to tables in relational databases) with tagged metadata and field values timestamped to nanosecond precision. This model enables extremely efficient storage of time-series data through compression techniques optimized for sequential timestamp data, and fast retrieval of time ranges, statistical aggregations, and downsampling queries that are the most common access patterns for monitoring and analytics workloads.

InfluxDB 3.0, the latest generation of the platform, is built on Apache Arrow and the Parquet columnar storage format, delivering significantly improved query performance and storage efficiency compared to previous versions. The platform's SQL support alongside its proprietary Flux query language provides flexibility for teams with different query language preferences and existing tooling.

The Telegraf open source agent, also developed by InfluxData, provides a plugin-based architecture for collecting, processing, and writing metrics and events from virtually any source to InfluxDB and other data stores. With more than 300 input, processor, and output plugins, Telegraf can collect from operating systems, databases, cloud APIs, MQTT brokers, and custom applications, making it a comprehensive data collection agent for heterogeneous monitoring environments.

InfluxDB Cloud provides a fully managed serverless time-series database service on AWS, Azure, and Google Cloud, with usage-based pricing that scales from individual developer projects to high-volume enterprise monitoring deployments. InfluxDB's ecosystem of integrations includes native connectors for Grafana, Chronograf, Kapacitor for stream processing and alerting, and bindings for Python, JavaScript, Go, Java, and other programming languages.
