您好我做了这个失败的测试 - 我已将模式设置为Production
并将allow_scans
设置为true
。我还在属性value
上设置了物化索引和搜索索引:
schema.propertyKey("value").Text().create()
schema.vertexLabel("Number").properties("value").create()
schema.vertexLabel('Number').index('byValue').materialized().by('value').add()
schema.vertexLabel('Number').index('search').search().by('value').asString().add()
我正在使用DSE 5.0.7
<dependency>
<groupId>com.datastax.dse</groupId>
<artifactId>dse-java-driver-graph</artifactId>
<version>1.2.3</version>
</dependency>
public class DatastaxTransactionTest {
private GraphTraversalSource g;
public GraphTraversalSource getGraph() {
DseCluster dseCluster = DseCluster.builder()
.addContactPoint("192.168.1.24")
.build();
DseSession dseSession = dseCluster.connect();
return DseGraph.traversal(dseSession, new GraphOptions().setGraphName("test"));
}
@Before
public void setUp() {
g = getGraph();
g.V().drop().iterate();
}
@After
public void clean() {
g.V().drop().iterate();
}
@Test
public void testTransactions() {
GraphTraversalSource g = getGraph();
g.V().drop().iterate();
for (int i=0; i<100; i++) {
boolean exists = g.V().has("Number", "value", "32").count().next().intValue() > 0;
// this works: boolean exists = g.V().count().next().intValue() > 0;
if (!exists) {
g.addV("Number").property("value","32").next();
report();
}
}
Assert.assertEquals(1, g.V().count().next().intValue()); //this is 100
Assert.assertEquals(1, g.V().has("Number", "value", "32").count().next().intValue()); // this is 0!!
}
public void report() {
int vCount = g.V().count().next().intValue();
int numberCount = g.V().hasLabel("Number").count().next().intValue();
int number32Count = g.V().has("Number", "value", "32").count().next().intValue();
System.out.println("added Number (Total Vs: "+vCount+ ", Number Vs: "+numberCount + ", Number 32 Vs: "+number32Count );
}
}
这只是在它不存在的情况下尝试插入一个数字顶点。纯数量的顶点上的存在工作正常,但不能通过索引工作..我的一些测试中他们传递的问题很大只是通过调试而不是运行..就好像索引没有绑定到事务但最终稍后更新..如果是这种情况则是一种非常糟糕的行为..
这是输出:
added Number (Total Vs: 1, Number Vs: 1, Number 32 Vs: 0
added Number (Total Vs: 2, Number Vs: 2, Number 32 Vs: 0
added Number (Total Vs: 3, Number Vs: 3, Number 32 Vs: 0
added Number (Total Vs: 4, Number Vs: 4, Number 32 Vs: 0
added Number (Total Vs: 5, Number Vs: 5, Number 32 Vs: 0
added Number (Total Vs: 6, Number Vs: 6, Number 32 Vs: 0
[...]
added Number (Total Vs: 97, Number Vs: 97, Number 32 Vs: 0
added Number (Total Vs: 98, Number Vs: 98, Number 32 Vs: 0
added Number (Total Vs: 99, Number Vs: 99, Number 32 Vs: 0
added Number (Total Vs: 100, Number Vs: 100, Number 32 Vs: 0
java.lang.AssertionError:
