windows7下使用MongoDB实现仓储设计

  • A+
所属分类:MongoDB

简单的先容一下,我使用MongoDB的场景。

我们如今的物联网情况下,有部门数据,采样频率为2000笔记录/分钟,如许下来一天24*60*2000=2880000约即是300万条数据,以后必然还会增长。之前数据库使用的是mssql,对付数据库的压力很年夜,同时又必要保证汗青查询的相应速率,这种环境下,在单表中数据量年夜,同时存在读写操作。不得已采纳MongoDB来存储数据。假如使用MongoDB,则至少必要三台机械,两台实现读写分别,一台作为仲裁(当然前提不容许也可以不消),每台机械的内存临时设置装备摆设在16G,公司小,没方法,听说,使用这个MongoDB必要机械内存起码92G,我没有验证过,然则吃内存是公认的,以是内存绝对要保证,就算保证了,也纷歧定完全就没故意外产生。我们上面的这些特殊的数据是容许少量的丧失的,这些只是做阐发使用的,几个月了,临时还没呈现数据丧失的环境,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阐明。下面直接奔入主题:

一、安装部署和设置装备摆设情况

1.安装部署mongo-server(V3.4)

参考 点击这里进入

这个时刻不要启动,接着设置装备摆设config文件

2.设置装备摆设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

以上是具体的设置装备摆设参数,此中路径部门依据必要变动, 这里设置的oplogsize年夜小为10G,依据营业场景进行调整,另外auth权限为null,由于设置权限会增长服务开销,影响效力,最下面几行是内存引擎,可以节制副本集同步及内存限定,防止内存泄露。

3.启动mongo-server

4.添加副本集设置装备摆设

此时副本集集群设置装备摆设已经完成,然后在敕令行中输入:rs.status(),查看副本集状况,必要查看同步环境,可以输入敕令:db.serverStatus().

5.设置副本集可读写

Rs.slaveOk()

6..NET操作mongo

衔接设置,请参考小我封装Unitoon.Mongo代码所示。

7.机能对照

读写速率:Redis>Mongo>Mssqlserver

可容纳数据量:Mssqlserver~Mongo>Redis

存储数据类型:Mongo>Mssqlserver>Redis

Note:内存连续上升,内部没有内存收受接管机制,若限定内存 ,则可能呈现查询速率变慢,数据丧失等问题,建议优化查询效力,树立索引

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

强制开释内存敕令:db.runCommand({closeAllDatabases:1})

二、仓储设计

1.基类BaseEntity

namespace UnitoonIot.Mongo
{
  /// <summary>
  /// 实体基类,便利天生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>
    /// 给工具初值
    /// </summary>
    public BaseEntity()
    {
      // this.ObjId = ObjectId.GenerateNewId().ToString();
      //this.Id = ObjectId.NewObjectId().ToString();
    }
  }
}

这里必要注意光阴格局,MongoDB默认光阴格局为国际光阴,以是在写入数据时和读取数据时,光阴格局要同等,此例中没有对光阴进行特殊处置,由传入的光阴格局肯定。

2.Repository承继接口IMongoRepository

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