alibaba/euler is a lightweight library built specifically for GNN sampling only. While GraphScope is built for many kinds of graph tasks such as gremlin, graph analytics and GNN sampling. You can check this example to get an idea what GraphScope can do. https://nbviewer.jupyter.org/github/alibaba/GraphScope/blob/main/demo/node_classification_on_citation.ipynb https://nbviewer.jupyter.org/github/alibaba/GraphScope/blob/... The graphs on GraphScope is backed by vineyard (https://github.com/alibaba/libvineyard https://github.com/alibaba/libvineyard). And that enables GraphScope to have multiple specifically optimized runtimes (written in C++, rust and Python) for different tasks shares the distributed graph data in memory efficiently.
