InfluxDB 3 queries data in real-time by leveraging the FDAP stack, which includes Flight, DataFusion, Arrow, and Parquet technologies. The database's high-performance analytics are supported by a custom ingester, compactor, catalog, caching, and file organization that work together to deliver speed and efficiency. Real-time analytics for time series data involves analyzing and extracting insights from time-stamped data immediately after it is ingested, with minimal latency. InfluxDB 3's real-time analytics rely heavily on its custom ingester, which prioritizes speed over durability and ACID compliance. The database also uses advanced caching techniques, flexible Parquet files, and optimized data organization to ensure fast query performance and efficient storage. By combining the power of open source tools with bespoke optimizations, InfluxDB 3 delivers high-performance capabilities for real-time analytics and time series workloads.
