# PreemptDB: Low-Latency Transaction Scheduling via Userspace Interrupts
PreemptDB a database engine that supports lightweight userspace preemptible transactions enabled by Intel x86 user interrupt (uintr).
PreemptDB allows high-priority, short-transactions to quickly preempt and pause long-running, low-priority transactions which is resumed after the short-transaction concludes.
Check out more details in our [SIGMOD 2025 paper](https://kaisonghuang.github.io/resources/preemptdb-preprint.pdf) (received *Best Paper Award*!). If you use our work, please cite:
