Replicate RSS Feeds to Multiple Databases
Replicate RSS feeds to disparate databases with a single configuration.
Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync for RSS integrates live RSS feeds into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote RSS feeds from Windows or any machine running Java.
You can use Sync's command-line interface (CLI) to easily control almost all aspects of the replication. You can use the CLI to replicate RSS feeds to one or many databases without any need to change your configuration.
Connect to RSS Feeds
You can save connection strings and other settings like email notifications in XML configuration files.
The following example shows how to replicate to SQLite.
Windows
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync><DatabaseType>SQLite</DatabaseType>
<DatabaseProvider>System.Data.SQLite</DatabaseProvider>
<ConnectionString>URI=http://broadcastCorp/rss/;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
<TaskSchedulerStartTime>09:51</TaskSchedulerStartTime>
<TaskSchedulerInterval>Never</TaskSchedulerInterval>
</CDataSync>
Java
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync><DatabaseType>SQLite</DatabaseType><DatabaseProvider>org.sqlite.JDBC</DatabaseProvider>
<ConnectionString>URI=http://broadcastCorp/rss/;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>
You can connect to RSS and Atom feeds, as well as feeds with custom extensions. To connect to a feed, set the URL property. You can also access secure feeds. A variety of authentication mechanisms are supported. See the help documentation for details.
Configure Replication Queries
Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the RSS API. The statement below caches and incrementally updates a table of RSS feeds:
REPLICATE Latest News;
You can specify a file containing the replication queries. This enables you to use the same replication queries to replicate to several databases.
Run Sync
After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:
Windows
RSSSync.exe -g MySQLiteConfig.xml -f RSSSync.sql
Java
java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar RSSSync.jar -g MySQLiteConfig.xml -f RSSSync.sql
