Why is nebula in python slow?
- https://discuss.nebula-graph.com.cn/t/topic/7285 (Chinese, but with python code)
- TL;DR:
- CPU-bound in case of huge returning data(unserilzation), multi-process should be considerred
- IO-bound in case of long query(like
count(*)), multi-thread helps only in this case
