Replicate Multiple Perigon Accounts via the CData Sync CLI

CData Sync for Perigon 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 Perigon connections. In this article we show how to use the CLI to replicate multiple Perigon accounts.

Configure Perigon Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple Perigon accounts, use multiple configuration files. Below is an example configuration to replicate Perigon to SQLite:

Windows

<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
  <DatabaseType>SQLite</DatabaseType>
  <DatabaseProvider>System.Data.SQLite</DatabaseProvider>
  <ConnectionString>Profile=C:\profiles\Perigon.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key"</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>Profile=C:\profiles\Perigon.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key"</ConnectionString>
  <ReplicateAll>False</ReplicateAll>
  <NotificationUserName></NotificationUserName>
  <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

Using API Key Authentication

To use the Perigon API, you need to obtain an API key from your Perigon account. Navigate to the Perigon dashboard and generate an API key from your account settings.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Perigon API key.

Example connection string:

Profile=C:\profiles\Perigon.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key"

Available Tables

The Perigon profile provides access to the following tables:

• Articles - News articles retrieved from the Perigon news intelligence API
• Headlines - Story clusters grouping related headline articles
• Sources - News sources tracked by the Perigon news intelligence API
• Journalists - Journalist profiles tracked by the Perigon news intelligence API

Configure Queries for Each Perigon 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 Perigon API. The statement below caches and incrementally updates a table of Perigon data:

REPLICATE Articles;

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 Perigon accounts into the same database:

You can use a different table prefix in the REPLICATE SELECT statement:

REPLICATE PROD_Articles SELECT * FROM Articles 

Alternatively, you can use a different schema:

REPLICATE PROD.Articles SELECT * FROM Articles

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

APISync.exe -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar APISync.jar -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql
