微軟分布式緩衝AppFabric（Velocity）－開發篇（一）開發環境準備

配置好快取叢集時，在windows services 中啟動名為：Microsoft project code named “Velocity”的服務，該服務預設不會自動啟動

1. 將Volocity的程式集copy到開發機器上。程式集位於Velocity的安裝目錄。程式集如下：

CacheBaseLibrary.dll,

ClientLibrary.dll,

 FabricCommon.dll,

 CASBase.dll.

2.在VS的工程中添加以上程式集的引用

3.配置快取用戶端的xml設定檔一般為.config檔案，或直接在代碼裡指定配置

選擇用Routing Cleing或Simple Client,選擇Routing Client會獲得最佳的效能。

 

Demo:

下面是一個Routing Client的配置樣本。樣本中未啟用本機快取，但使用了兩個緩衝主機：CacheServer1和CacheServer2

<?xml version="1.0" encoding="utf-8" ?><configuration>    <!--configSections must be the FIRST element -->  <configSections>        <!-- required to read the <dataCacheClient> element -->    <section name="dataCacheClient"       type="Microsoft.Data.Caching.DataCacheClientSection,       CacheBaseLibrary"       allowLocation="true"       allowDefinition="Everywhere"/>        <!-- required to read the <fabric> element, when present -->    <section name="fabric"       type="System.Data.Fabric.Common.ConfigFile,       FabricCommon"       allowLocation="true"       allowDefinition="Everywhere"/>      </configSections>    <!-- routing client-->  <dataCacheClient deployment="routing">    <!-- (optional) specify local cache     <localCache      isEnabled="true"      sync="TTLBased"      objectCount="100000"      ttlValue="300" />    -->    <!--(optional) specify cache notifications poll interval     <clientNotification pollInterval="300" />    -->        <!-- cache host(s) -->        <hosts>      <host         name="CacheServer1"         cachePort="22233"         cacheHostName="DistributedCacheService"/>      <host         name="CacheServer2"         cachePort="22233"         cacheHostName="DistributedCacheService"/>    </hosts>  </dataCacheClient></configuration>

 

 

下面代碼示範如何在代碼中指定配置

//declare array for cache host(s)DataCacheServerEndpoint[] servers = new DataCacheServerEndpoint[1];//specify cache host(s)servers[0] = new DataCacheServerEndpoint("CacheServer2",                         22233, "DistributedCacheService");//specify cache client configurationDataCacheFactory mycacheFactory     = new DataCacheFactory(servers, true, false);//get cache client for cache "NamedCache1"DataCache myDefaultCache = mycacheFactory.GetCache("NamedCache1");
