Time series without trade offs
The only time-series database that doesn't make you choose between performance, developer experience, and operational simplicity.
Ingestion efficiency at massive scale
Multi-primary writes and columnar storage handle millions of rows per second, even with high cardinality data. Native InfluxDB Line Protocol support means existing pipelines integrate instantly.
Query billions of rows in milliseconds
Custom query engine with vectorized execution delivers sub-millisecond latency. Memory-mapped architecture eliminates I/O bottlenecks—queries run at CPU speed, not storage speed.
