Question

我尝试了一些实验，我想知道VoltDB社区与企业之间的差异。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.

我想知道问题是什么？非常感谢您的帮助！

VoltDB社区版中不提供数据库复制。 XDCR（主动/主动，主动/被动），高可用性，导出和完全耐用性仅在企业版中可用。我们的github wiki页面提供了这里的差异的简要描述： https://github.com/VoltDB/voltdb#commercial-voltdb-differences

谢谢，

VoltDB的社区版是否支持被动数据库复制？
