我是JMeter和Cassandra的新手,并尝试使用Apache Jmeter Cassandra插件进行测试

https://github.com/Netflix/CassJMeter/wiki

按照给出的步骤,我可以配置JMeter Cassandra插件.

1. 在JMeter控制台中,我创建了一个New ThreadGroup-> CassandraProperties,并在那里指定了所有与Cassandra相关的属性.

2. 添加了SchemaProperties,如下所示.

3. 添加了Cassandra获取范围切片

但是当我开始测试时,我在样本结果中获得了成功响应,但我的响应数据是空的

我的Users表不是空的,使用cql我可以查询数据,其架构如下:

CREATE TABLE users (
  user_name text,
  gender text,
  password text,
  PRIMARY KEY ((user_name))
) WITH
  bloom_filter_fp_chance=0.010000 AND
  caching='KEYS_ONLY' AND
  comment='' AND
  dclocal_read_repair_chance=0.100000 AND
  gc_grace_seconds=864000 AND
  index_interval=128 AND
  read_repair_chance=0.000000 AND
  replicate_on_write='true' AND
  populate_io_cache_on_flush='false' AND
  default_time_to_live=0 AND
  speculative_retry='99.0PERCENTILE' AND
  memtable_flush_period_in_ms=0 AND
  compaction={'class': 'SizeTieredCompactionStrategy'} AND
  compression={'sstable_compression': 'LZ4Compressor'};

因此,当我执行Jmeter控制台时,我应该获得100计数结果和一些响应数据吗？我被困在这里,无法理解......任何帮助将不胜感激.

我是Cassandra的新手,在这个例子中,我使用的是一个具有1个DC和5个节点的集群,以及一个复制因子为3的NetworkTopologyStrategy.

我有一个条件,我需要从队列中读取数据并相应地处理它.因此我为此目的使用apache-camel.

现在我的Camel配置如下:

applicationContext.xml中

<camel:camelContext id="camel-server">
        <camel:package>com.sorc.processor.route</camel:package>
        <camel:jmxAgent id="agent" createConnector="true" />
</camel:camelContext>

FeedProcessorRoute.java

public class FeedProcessorRoute extends RouteBuilder{
    private @Value("${activemq_feed_observer_queue_name}") String activemqQueueName;
    @Override
    public void configure() throws Exception {
        from("amq:" + activemqQueueName + "?exchangePattern=InOut&preserveMessageQos=true")
            .routeId("id1") // Set the routeId to the class name. The routeId is printed when logging.
            .process(this.feedProcessorTrigger)
            .log("The FeedProcessor route has finished\n\n"));  
    }

FeedProcessorTrigger.java

  public class FeedProcessorTrigger implements Processor{
  @Override
  public void process(Exchange exchange) throws Exception {
            //I have added my processing logic here
    }
 }

当我在tomcat中部署我的战争时,我得到以下错误

15:06:24.602 …

我有一种情况，我正在使用angularJs智能表进行过滤。

的HTML：

<section class="main" ng-init="listAllWorkOrderData()">
    <table st-table="listWorkOrderResponse">
     <thead>
            <tr>
                <th st-sort="id">ID <i></i></th>
                <th st-sort="project">Project <i></i></th>
            </tr>
     </thead>
     <tbody ng-repeat="workOrder in listWorkOrderResponse">
             <tr>
                <td>{{workOrder.id}}</td>
                <td>{{workOrder.project}}</td>
             </tr>
             <tr>
                <td></td>
             </tr>
     </tbody>
    </table>
</section>

我正在测试2种不同的情况。

在我的控制器中，我首先调用相同的函数，但发送虚拟数组，在第二种情况下，我发送从api调用接收的数组。

1. Dummy data


$scope.listAllWorkOrderData = function () {
     var listWorkOrderResponse = [{"id":"1","project":"project1"},{"id":2,"project":"project2"},{"id":"3","project":"project3"}];
    }

2. I am using a service and fetching data through api.

        $scope.listAllWorkOrderData = function () {
                    TestService.listAllWorkOrderData().then(function (response, status, headers, config) {
                        if (response != undefined && response != null) {
                            if (!$scope.listWorkOrderResponse) { …

我写了这段代码,但它不起作用!

它是C++中动态堆栈节点的实现:

template <class E>

class Record{

public:

    E elem;

    Record<E> *prec;
};


typedef Record<E> *P; <- error!

我无法解决它,任何解决方案？谢谢

我创建了以下查询,当我传递所有关系时,它可以正常工作.

@Query(value="START profile=node(*) "
                + "MATCH profile - [rel:create | stream | like | follow] - feeds "
                + "WHERE profile.id ={profileId} "
                + "WITH distinct feeds as feed, rel.date as date "
                + "ORDER BY date DESC "
                + "RETURN DISTINCT feed;")
    public List<Feed> findByProfileId(@Param("profileId") String profileId);

但我想获取特定操作的数据,如下面的查询

@Query(value="START profile=node(*) "
                + "MATCH profile - [rel:{action}] - feeds "
                + "WHERE profile.id ={profileId} "
                + "WITH distinct feeds as feed, rel.date as date "
                + "ORDER BY date DESC …
