OpenTSDB
OpenTSDB is an open-source, distributed time series database built on top of Apache HBase. It is designed to store and serve massive amounts of time series data, such as metrics from servers, applications, or IoT devices, with high scalability and performance. It provides a simple HTTP API and query language for data ingestion and retrieval, making it suitable for monitoring and analytics applications.
Developers should learn and use OpenTSDB when they need to handle large-scale time series data, such as system monitoring, application performance metrics, or sensor data from IoT devices. It is particularly valuable in DevOps and infrastructure monitoring scenarios where high write throughput and long-term data retention are required, as it efficiently compresses and stores timestamped data points.
