Expressjs和node-cassandra-cql发布时间约为120000毫秒

Question

我不知道发生了什么事有时cassandra很容易提交帖子并在~20ms内存储数据，而其他时间帖子需要~120000ms但是帖子没有提交（即存储）。任何建议伙伴我两天都在努力解决这个问题 我在bellow查询中没有发现任何错误。我索引了已检查的列。

这是我的主要应用文件：

 var express=require('express'),
app=express(),
morgan=require('morgan'),
bodyParser=require('body-parser'),
methodOverride=require('method-override'),
cookieParser=require('cookie-parser'),
sessions=require('express-session'),
passport=require('passport'),
path=require('path'),
cassandra=require('node-cassandra-cql'),
port=3000;

 var cassandraSettings=require('./config/cassandra').setting;
 cassandraClient = new cassandra.Client(cassandraSettings);
 cassandraClient.connect(function(error){
if(error)
    console.log('error - ' + error);
else
    console.log('Logged In to Cassandra');
 });



var cassandraConfig={
readConsistency:cassandra.types.consistencies.one,
writeConsistency:cassandra.types.consistencies.any,
cassandra:cassandra,
cassandraClient:cassandraClient
}

require('./config/passport')(passport,cassandraConfig);

app.use(morgan('dev'))
.use(bodyParser())
.use(methodOverride())
.use(cookieParser())
.use(sessions({name:"sid",cookie:{maxAge:1000*60*60*24*30},secret:"Ankit"}))
.use(passport.initialize())
.use(passport.session());




//url for statics
app.use('/static', express.static(__dirname + '/views'));

 require('./routes/login')(app,passport);
 require('./routes/signup')(app,passport);
 //Used to insert Sport, League, TeamDetails 
  require('./routes/private/insert_sport_detail')(app,cassandraConfig);
 //require('./routes/private/insert_league_detail')(app,cassandraConfig);

 app.listen(port);

我的cassandra route.js：

  var queries={
insert:{
    sport_detail:{
        query:'INSERT INTO only_sport_detail(sportid,sport_name,sport_short_name,time_made,checked) VALUES (?,?,?,?,?)'
    },
    league_detail:{
        query:'INSERT INTO only_league_detail(leagueid,league_name,league_short_name,league_abbreviation,league_location,time_made,checked) VALUES (?,?,?,?,?,?,?)'
    }
},
retrieve:{
    sport_detail:{
        query:'SELECT * FROM only_sport_detail WHERE checked=?'
    },
    league_detail:{
        query:'SELECT * FROM only_league_detail WHERE checked=?'
    }
}
 };

   module.exports=function(app,cassandraConfig){

        writeConsistency,
        function(err){
            if(!err)
            {

                cassandraClient.executeAsPrepared(

                    [1],
                    function(err,result){
                        if(err)
                        {
                            console.log(err);
                            res.send('Sorry error');
                            res.end();
                        }
                        else
                        {
                            res.json(result.rows);
                            res.end();
                        }
                    }
                );
            }
        }
    );

});

app.get('/get/detail/sport',function(req,res){
    cassandraClient.executeAsPrepared(
        queries.retrieve.sport_detail.query,

            }
            else

        }
    );
});
