在一台电脑上开个3个端口,Replica Set模式,刚刚新建了一个新DB和新的collection,往这个collection中插入3000多条数据,第一次只能插入1600多条,删库,然后第二次1700多条,第三次1800多条。电脑是32位的老机器,这3000多条数据大小也就是125Kb。用的还java的API。
Mongo mongo = null; MongoURI uri=new MongoURI("mongodb://localhost:27017,localhost:27018,localhost:27019"); mongo=new Mongo.Holder().connect(uri); mongo.slaveOk(); DB db=mongo.getDB("words"); DBCollection co= db.getCollection("test"); String pa="c:\\111.txt"; FileReader fr; fr = new FileReader(pa); BufferedReader in=new BufferedReader(fr); String line=null; while((line=in.readLine())!=null) { BasicDBObject document = new BasicDBObject(); String datas[]=line.split("-"); int id=Integer.parseInt(datas[0]); document.put("_id",id); document.put("name",datas[1]); co.insert(document); System.out.println(id+" "+datas[1]); }

Mongo is not safe for writing. To ensure that there is no problem, it is best to getLastError
