Welcome to Milvus
What is Milvus
Milvus is an open source similarity search engine for massive feature vectors. Designed with heterogeneous computing architecture for the best cost efficiency. Searches over billion-scale vectors take only milliseconds with minimum computing resources.
Milvus provides stable Python, Java and C++ APIs.
Keep up-to-date with newest releases and latest updates by reading Milvus release notes.
-
GPU-accelerated search engine
Milvus uses CPU/GPU heterogeneous computing architecture to process feature vectors, and are orders of magnitudes faster than traditional databases.
-
Multiple indexes
Milvus supports a variety of indexing types that employs quantization, tree-based, and graph indexing techniques.
-
Intelligent resource management
Milvus optimizes the search computation and index building according to your data size and available resources.
-
Horizontal scalability
Milvus expands computation and storage by adding nodes during runtime, which allows you to scale the data size without redesigning the system.

Compilation
Step 1 Install dependencies
$ cd [Milvus sourcecode path]/core
./ubuntu_build_deps.sh
Step 2 Build
$ cd [Milvus sourcecode path]/core
$ ./build.sh -t Debug
or
$ ./build.sh -t Release
When the build is completed, all the stuff that you need in order to run Milvus will be installed under [Milvus root path]/core/milvus.
Launch Milvus server
$ cd [Milvus root path]/core/milvus
Add lib/ directory to LD_LIBRARY_PATH
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/milvus/lib
Then start Milvus server:
$ cd scripts
$ ./start_server.sh
To stop Milvus server, run:
$ ./stop_server.sh
To edit Milvus settings in conf/server_config.yaml and conf/log_config.conf, please read Milvus Configuration.
