How to Build an ETL App for Telegram Data in Python with CData

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData API Driver for Python and the petl framework, you can build Telegram-connected applications and pipelines for extracting, transforming, and loading Telegram data. This article shows how to connect to Telegram with the CData Python Connector and use petl and pandas to extract, transform, and load Telegram data.

With built-in, optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Telegram data in Python. When you issue complex SQL queries from Telegram, the driver pushes supported SQL operations, like filters and aggregations, directly to Telegram and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to Telegram Data

Connecting to Telegram data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.

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';

After installing the CData Telegram Connector, follow the procedure below to install the other required modules and start accessing Telegram through Python objects.

Install Required Modules

Use the pip utility to install the required modules and frameworks:

pip install petl
pip install pandas

Build an ETL App for Telegram Data in Python

Once the required modules and frameworks are installed, we are ready to build our ETL app. Code snippets follow, but the full source code is available at the end of the article.

First, be sure to import the modules (including the CData Connector) with the following:

import petl as etl
import pandas as pd
import cdata.api as mod

You can now connect with a connection string. Use the connect function for the CData Telegram Connector to create a connection for working with Telegram data.

cnxn = mod.connect("Profile=C:\profiles\Telegram.apip;ProfileSettings='APIKey=your_bot_token';")

Create a SQL Statement to Query Telegram

Use SQL to create a statement for querying Telegram. In this article, we read data from the AvailableGifts entity.

sql = "SELECT ,  FROM AvailableGifts WHERE  = ''"

Extract, Transform, and Load the Telegram Data

With the query results stored in a DataFrame, we can use petl to extract, transform, and load the Telegram data. In this example, we extract Telegram data, sort the data by the column, and load the data into a CSV file.

Loading Telegram Data into a CSV File

table1 = etl.fromdb(cnxn,sql)

table2 = etl.sort(table1,'')

etl.tocsv(table2,'availablegifts_data.csv')

With the CData API Driver for Python, you can work with Telegram data just like you would with any database, including direct access to data in ETL packages like petl.
