Replicate Telegram 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 Telegram integrates live Telegram data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote Telegram 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 Telegram data to one or many databases without any need to change your configuration.

Connect to Telegram 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>Profile=C:\profiles\Telegram.apip;ProfileSettings='APIKey=your_bot_token';</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\Telegram.apip;ProfileSettings='APIKey=your_bot_token';</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

Using API Key Authentication

Telegram uses Bot Tokens to authenticate API requests. You can obtain a Bot Token by creating a bot via BotFather on Telegram (https://t.me/BotFather). Once created, BotFather will provide a token in the format

123456789:ABCdefGhIJKlmNoPQRsTUVwxyZ

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

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Telegram Bot Token obtained from BotFather.

Example connection string

Profile=C:\profiles\Telegram.apip;ProfileSettings='APIKey=your_bot_token';

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 Telegram API. The statement below caches and incrementally updates a table of Telegram data:

REPLICATE AvailableGifts;

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

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

Java

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