InfluxDB is an open-source time-series database designed for high-performance storage and retrieval of time-stamped data, such as metrics, events, and logs.
What is InfluxDB?
InfluxDB is a purpose-built time-series database developed to handle high-write and query loads of time-stamped data. It is highly optimized for storing numerical values and strings associated with timestamps, making it ideal for IoT, monitoring systems, and real-time analytics. Its schema-less design simplifies data ingestion, and its query language (InfluxQL) makes it intuitive to retrieve and analyze data. InfluxDB is available in both open-source and enterprise versions, with features like clustering, high availability, and integrated analytics.
Main Features
InfluxDB offers a powerful set of features tailored for time-series data management, allowing it to handle complex workloads efficiently.
Key features include:
- Optimized Time-Series Storage: Uses a custom storage engine for high-performance data ingestion and retrieval.
- Schema-Free Design: Automatically adapts to new data without requiring predefined schemas.
- InfluxQL and Flux: Provides two query languages for flexible data retrieval and transformation.
- High Write Throughput: Can handle millions of points per second, ideal for real-time scenarios.
- Retention Policies: Automatically expire data based on user-defined time limits, optimizing storage use.
- Downsampling: Aggregates data over time to maintain long-term trends without overwhelming storage.
- Integrations: Supports popular tools like Grafana, Telegraf, and Kapacitor for visualization, data collection, and processing.
- Tags for Efficient Queries: Organize data with tags to enable fast and filtered searches.
- Edge and Cloud Deployment: Works across edge devices, local servers, and cloud environments.
- Continuous Queries: Automatically calculate and store results for frequently used queries.
