KairosDB: Fast Open Source Time Series Database
A scalable time series database designed to analyze large amounts of time-stamped data, built on Cassandra for high performance and scalability.
What is KairosDB?
KairosDB is an open source distributed time series database written in Java that is designed to efficiently store and query massive amounts of time-series data. It is built on top of Apache Cassandra to leverage its scalability and high availability.
Some key features of KairosDB include:
- High write throughput to handle large volumes of time-series data
- Advanced querying through predicates and groupby functions
- Tagging for faster queries and easier management of similar metrics
- Downsampling for data retention over long periods
- Pluggable storage engines, allowing other databases like H2 to be used for storage
- Web UI and REST API for easy access and integration
- Horizontal scalability through Cassandra's distributed architecture
KairosDB is commonly used for IoT applications, metrics collection and monitoring, analytics, and other time-series data use cases. Its flexibility and scalability make it well suited for modern big data applications.
