Replicate Multiple Yahoo! Japan Data Solution Accounts
Replicate multiple Yahoo! Japan Data Solution accounts to one or many databases.
CData Sync for Yahoo! Japan Data Solution is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. Both Sync for Windows and Sync for Java include a command-line interface (CLI) that makes it easy to manage multiple Yahoo! Japan Data Solution connections. In this article we show how to use the CLI to replicate multiple Yahoo! Japan Data Solution accounts.
Configure Yahoo! Japan Data Solution Connections
You can save connection and email notification settings in an XML configuration file. To replicate multiple Yahoo! Japan Data Solution accounts, use multiple configuration files. Below is an example configuration to replicate Yahoo! Japan Data Solution to SQLite:
Windows
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
<DatabaseType>SQLite</DatabaseType>
<DatabaseProvider>System.Data.SQLite</DatabaseProvider>
<ConnectionString>APPID=YOUR_APP_ID</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>APPID=YOUR_APP_ID</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>
In order to authenticate, specify the following:
- AppID: The App ID used for authentication. Send a request to the Yahoo! Japan Data Solution support team to obtain your App ID.
- (Optional) Search Keyword: Specify any value to search for.
Configure Queries for Each Yahoo! Japan Data Solution Instance
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 Yahoo! Japan Data Solution API. The statement below caches and incrementally updates a table of Yahoo! Japan Data Solution data:
REPLICATE SearchVolume;
You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple Yahoo! Japan Data Solution accounts into the same database:
You can use a different table prefix in the REPLICATE SELECT statement:
REPLICATE PROD_SearchVolume SELECT * FROM SearchVolume
Alternatively, you can use a different schema:
REPLICATE PROD.SearchVolume SELECT * FROM SearchVolume
Run Sync
After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:
Windows
YahooDSSync.exe -g MyProductionYahooDSConfig.xml -f MyProductionYahooDSSync.sql
Java
java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar YahooDSSync.jar -g MyProductionYahooDSConfig.xml -f MyProductionYahooDSSync.sql
