About AresDB

AresDB is a real-time analytics storage and query engine created by Uber Engineering that uses GPU acceleration to speed up queries. It is aimed at teams that need low query latency and high data freshness over large analytical datasets, going beyond what CPU-only engines can comfortably deliver.

The engine features efficient in-memory and on-disk storage management alongside its GPU-based query execution, with the architecture and design rationale described in a Uber Engineering blog post. The project combines a query engine written in C++ with the CUDA toolkit, and memory store, disk store and other query components written in Go, and it can also run in a CPU-only mode when a GPU is not available.

Building and running AresDB requires Go 1.11 or newer, a C++14-capable compiler, CMake, NVIDIA drivers and CUDA, with specific version requirements documented in the repository. It is released under the Apache-2.0 license, and using its GPU features requires accepting NVIDIA's CUDA End User License Agreement.
