  • option 0 https://github.com/vesoft-inc/nebula-exchange/issues/57
    • nebula-spark-connector & dgraph-spark-connector
  • option 1 https://github.com/jievince/rdf-converter

• 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

• GraphD crash on CGROUPv2 OS/Container host OS

  • https://github.com/vesoft-inc/nebula/issues/3278
  • 2.6.2 is on the way
