About InfluxDB
InfluxDB is a popular open-source time-series database developed by InfluxData, designed to handle high-velocity writes and real-time queries for monitoring, IoT, and analytics use cases. InfluxDB has evolved through multiple versions, with v1 and v2 using a custom storage engine (TSM), while v3 adopts Apache Parquet and Arrow for better performance and compatibility. It features InfluxQL (similar to SQL) and Flux query languages for data analysis. Click here to read the full performance comparison report between GreptimeDB and InfluxDB.
