    7. UnsupportedOperationException In Match

    8. Create cluster error with console

  • 未解决

    1. Can not use the method of shortestPath()

    2. Pattern Matching’ difference between OrientDB and Gremlin

    4. Property is absent In Creating Index

    5. Save String data error

    6. Letters in orientdb and gremlin
