Java Janusgraph:Cassandra节俭超时异常
我使用嵌入式格式的Janusgraph，后端为cassandrathrift。以下是我对janusgraph和cassandra的属性：Java Janusgraph:Cassandra节俭超时异常,java,graph,cassandra,janusgraph,Java,Graph,Cassandra,Janusgraph,我使用嵌入式格式的Janusgraph，后端为cassandrathrift。以下是我对janusgraph和cassandra的属性： storage.backend=cassandrathrift storage.cassandra.keyspace=t_graph storage.cassandra.frame-size-mb=128 storage.hostname=10.XX.XX.XX,20.XX.XX.XX,30.XX.XX.XX 我有一个查询，它找出了一个特定顶点的跟随者数。以
storage.backend=cassandrathrift
storage.cassandra.keyspace=t_graph

GraphTraversal<Vertex, Vertex> gt = allV.has("vid", "supernode");
GraphTraversal<Vertex, Long> c = gt.inE()
.count();
long l = c.next();
System.out.println("All edges = "+l);
graph.tx().commit();
return l;
}catch (Exception e) {
System.out.println("Error while fetching the edges for : ");
e.printStackTrace();

return -1;

但没有一个解决方案对我有效。关于如何解决这个问题有什么建议吗？将存储后端更改为cql以及与cql相关的其他属性为我解决了这个问题。 以下是我使用的属性：
storage.backend=cql
storage.cql.keyspace=t_graph
storage.cql.read-consistency-level=ONE
