Replicate Azure Data Catalog Data to Multiple Databases via the CData Sync CLI

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync for Azure Data Catalog integrates live Azure Data Catalog data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote Azure Data Catalog data 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 Azure Data Catalog data to one or many databases without any need to change your configuration.

Connect to Azure Data Catalog Data

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>InitiateOAuth=GETANDREFRESH;</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>InitiateOAuth=GETANDREFRESH;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

You can optionally set the following to read the different catalog data returned from Azure Data Catalog.

<>CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name

Connect Using OAuth Authentication

You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.

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 Azure Data Catalog API. The statement below caches and incrementally updates a table of Azure Data Catalog data:

REPLICATE Tables;

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

AzureDataCatalogSync.exe -g MySQLiteConfig.xml -f AzureDataCatalogSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar AzureDataCatalogSync.jar -g MySQLiteConfig.xml -f AzureDataCatalogSync.sql
