windows7下使用MongoDB实现仓储设计

内容简介：本文给大家介绍了本人在物联网环境下基于MongoDB实现的仓储的配置信息及具体的使用示例，非常的实用，有需要的小伙伴可以参考下

简单的介绍一下，我使用 MongoDB 的场景。

我们现在的物联网环境下，有部分数据，采样频率为2000条记录/分钟，这样下来一天24*60*2000=2880000约等于300万条数据，以后必然还会增加。之前数据库使用的是mssql，对于数据库的压力很大，同时又需要保证历史查询的响应速度，这种情况下，在单表中数据量大，同时存在读写操作。不得已采用MongoDB来存储数据。如果使用MongoDB，则至少需要三台机器，两台实现读写分离，一台作为仲裁（当然条件不允许也可以不用），每台机器的内存暂时配置在16G，公司小，没办法，据说，使用这个MongoDB需要机器内存最少92G，我没有验证过，但是吃内存是公认的，所以内存绝对要保证，就算保证了，也不一定完全就没有意外发生。我们上面的这些特殊的数据是允许少量的丢失的，这些只是做分析使用的，几个月了，暂时还没出现数据丢失的情况，可能最新版本早就修复了吧，新手使用建议多看下官网上的说明。下面直接奔入主题：

一、安装部署和配置环境

1.安装部署mongo-server（V3.4）

参考点击这里进入

这个时候不要启动，接着配置config文件

2.配置Config文件

dbpath=C:/Program Files/MongoDB/Server/3.4/bin/data/db 
logpath=C:/Program Files/MongoDB/Server/3.4/bin/data/log/master.log 
pidfilepath=C:/Program Files/MongoDB/Server/3.4/bin/master.pid 
directoryperdb=true 
logappend=true 
replSet=testrs 
bind_ip=10.1.5.25
port=27016 
oplogSize=10000
noauth = true
 
storageEngine = wiredTiger
wiredTigerCacheSizeGB = 2
syncdelay = 30
wiredTigerCollectionBlockCompressor = snappy

以上是详细的配置参数，其中路径部分根据需要更改，这里设置的oplogsize大小为10G，根据业务场景进行调整，另外auth权限为null，因为设置权限会增加服务开销，影响效率，最下面几行是内存引擎，可以控制副本集同步及内存限制，防止内存泄露。

3.启动mongo-server

4.添加副本集配置

conf=
{
  "_id" : "testrs",
  "members" : [
    { "_id" : 0, "host" : "10.1.5.25:27016" },
    { "_id" : 1, "host" : "10.1.5.26:27016" },
    { "_id" : 2, "host" : "10.1.5.27:27016" }
  ]
}

rs.initiate(conf)

此时副本集集群配置已经完成，然后在命令行中输入：rs.status()，查看副本集状态，需要查看同步情况，可以输入命令：db.serverStatus().

5.设置副本集可读写

Rs.slaveOk()

6..NET操作mongo

连接设置，请参考个人封装Unitoon.Mongo代码所示。

7.性能对比

读写速度：Redis>Mongo>Mssqlserver

可容纳数据量：Mssqlserver~Mongo>Redis

存储数据类型：Mongo>Mssqlserver>Redis

Note：内存持续上升，内部没有内存回收机制，若限制内存，则可能出现查询速度变慢，数据丢失等问题，建议优化查询效率，建立索引

Db.test.ensureIndex({"username":1, "age":-1})

强制释放内存命令：db.runCommand({closeAllDatabases:1})

二、仓储设计

1.基类BaseEntity

namespace UnitoonIot.Mongo
{
  /// <summary>
  /// 实体基类，方便生成ObjId
  /// </summary>
  [Serializable]
  [ProtoContract(ImplicitFields = ImplicitFields.AllPublic)]
  //[ProtoInclude(10, typeof(NormalHistory))]
  public class BaseEntity
  {
    //[BsonRepresentation(BsonType.ObjectId)]
    public ObjectId Id { get; set; }
 
    /// <summary>
    /// 数据库名称
    /// </summary>
    public string DbName { get; set; }
 
    /// <summary>
    /// 给对象初值
    /// </summary>
    public BaseEntity()
    {
      // this.ObjId = ObjectId.GenerateNewId().ToString();
      //this.Id = ObjectId.NewObjectId().ToString();
    }
  }
}

这里需要注意时间格式，MongoDB默认时间格式为国际时间，所以在写入数据时和读取数据时，时间格式要一致，此例中没有对时间进行特殊处理，由传入的时间格式确定。

2.Repository继承接口IMongoRepository

namespace UnitoonIot.Mongo
{
  public interface IMongoRepository<TEntity> where TEntity : class
  {
  }
}
