OrientDB is the most versatile DBMS supporting Graph, Document, Reactive, Full-Text and Geospatial models in one Multi-Model product. OrientDB can run distributed (Multi-Master), supports SQL, ACID Transactions, Full-Text indexing and Reactive Queries.
Version:orientdb-community-2.0-M3
Setup : Distributed mode with 2 nodes running (only modified "writeQuorum": 1 rest are all defaults)
Using Java client opening connection in remote mode.using Tx Graph
Creating Vertex1 -> This is getting created properly in both nodes
Creating Vertex2 and edge between Vertex1 and Vertex2 -> There are 2 entries of Vertex2 getting created in both nodes instead of 1.(The entries are exactly same except @version is 1 and 2)
This is working fine in non-distributed mode.
main method:
OrientGraphFactory factory = new OrientGraphFactory("remote:localhost/test","admin","admin");
graph = factory.getTx();
testVertex1Create(graph);
testVertex2Create(graph);
graph.commit();
