Peak performance time-series

Hyper ingestion

For massive volumes of time-series data, trust a specialized time-series database. Timestamps are first-class, and blistering throughput is sustained even through the highest data cardinality. Deduplication and out-of-order ingestion also work right out-of-the-box.

Better on a Pi, best on full hardware

Max performance, min hardware

Compute costs keep rising. Keep them low with an efficient solution. QuestDB runs well on low hardware, within high cardinality data and with deduplication and out-of-order indexing. On just a 4GB Raspberry Pi, QuestDB outperforms competitors on robust hardware. Have robust hardware? QuestDB scales up to many millions of rows per second.
