# perform data cleaning and transformationĬontents of transform.py file The DatabaseĪirflow comes with a SQLite3 database. Postgres_sql_upload.bulk_load('twitter_etl_table', data) Postgres_sql_upload = PostgresHook(postgres_conn_id="postgres_connection") Tweets_df = pd.DataFrame(tweets_list, columns=)įrom _hook import PostgresHookĭata = data.to_csv(index=None, header=None) Tweets_list.append([tweet.date,, tweet.rawContent, Inside the Airflow dags folder, create two files: extract.py and transform.py.Įxtract.py: import as sntwitterįor i,tweet in enumerate(sntwitter.TwitterSearchScraper('Chatham House since:').get_items()): Make sure your Airflow virtual environment is currently active. You will also need Pandas, a Python library for data exploration and transformation. Numerous libraries make it easy to connect to the Twitter API. To get data from Twitter, you need to connect to its API. Tons of data is generated daily through this platform. Twitter is a social media platform where users gather to share information and discuss trending world events/topics. An understanding of the building blocks of Apache Airflow (Tasks, Operators, etc).Airflow development environment up and running.Apache Airflow installed on your machine.To follow along with this tutorial, you'll need the following: It will download data from Twitter, transform the data into a CSV file, and load the data into a Postgres database, which will serve as a data warehouse.Įxternal users or applications will be able to connect to the database to build visualizations and make policy decisions. In this guide, you will be writing an ETL data pipeline. Airflow makes it easier for organizations to manage their data, automate their workflows, and gain valuable insights from their data With Airflow, data teams can schedule, monitor, and manage the entire data workflow. Data Orchestration involves using different tools and technologies together to extract, transform, and load (ETL) data from multiple sources into a central repository.ĭata orchestration typically involves a combination of technologies such as data integration tools and data warehouses.Īpache Airflow is a tool for data orchestration.
