【问题描述】：

我尝试了一些实验，想知道 VoltDB 社区和企业之间的区别。我这样做了：

    1. I wrote some words into the deployment.xml of the Master Cluster:
       <dr id="1" />
    2. Then I started the Master Cluster successd.
       [The Master Cluster started successfully.][http://i.stack.imgur.com/BO5e9.png]


    3. I wrote some words into the deployment.xml of the Replica Cluster:
       <dr id="2">
           <connection source="voltsvr1" />
       </dr>
    4. I created a table into the Master Cluster:
       CREATE TABLE STORE (
       KEYSPACE varbinary(128) NOT NULL,
       KEY varchar(128) NOT NULL,
       VALUE varbinary(2056) NOT NULL,
       PRIMARY KEY (KEYSPACE, KEY)
       );
       PARTITION TABLE STORE ON COLUMN KEY;
       DR TABLE STORE;

    5. Then I started the Replica Cluster with --replica option:
       [The Replica Cluster started successfully.][http://i.stack.imgur.com/5zbxJ.png]


    6. I used the same statements to create a same table store like the  table in the      Master Cluster:
       CREATE TABLE STORE (
       KEYSPACE varbinary(128) NOT NULL,
       KEY varchar(128) NOT NULL,
       VALUE varbinary(2056) NOT NULL,
       PRIMARY KEY (KEYSPACE, KEY)
       );
       PARTITION TABLE STORE ON COLUMN KEY;
       DR TABLE STORE;

    7. I loaded some data into the table store of the Master Cluster, but   the table store of Replica Cluster could't get data from the Master Cluster.

我想知道有什么问题？非常感谢您的帮助！

【解决方案1】：

数据库复制在 VoltDB 的社区版中不可用。 XDCR（主动/主动、主动/被动）、高可用性、导出和完全持久性仅在企业版中可用。我们的 github wiki 页面简要描述了这里的差异： https://github.com/VoltDB/voltdb#commercial-voltdb-differences
