"With Airbyte, we could just push a few buttons, allow API access, and bring all the data into Google BigQuery. By blending all the different marketing data sources, we can gain valuable insights."
Begin by exporting the data you need from AppFollow. Depending on the data size and type, you can use AppFollow’s export functionality to download the data as CSV, JSON, or any other supported format. Ensure you have the necessary permissions to access and export the required data.
Once you have downloaded the data, inspect it and ensure it is clean and well-structured. If necessary, format the data to match the schema of your ClickHouse tables. This might include renaming columns, changing data types, or removing unnecessary data to ensure compatibility with ClickHouse.
If not already installed, download and install the ClickHouse client on your workstation or server where you will manage the data import. The ClickHouse client is a command-line tool that allows you to interact with your ClickHouse instance directly.
Use the ClickHouse client to create the necessary database and tables that match the structure of your AppFollow data. Execute SQL commands to define the schema, taking into account data types and indexing strategies that will optimize query performance.
Convert your data into a format that ClickHouse can ingest, typically TSV (Tab-Separated Values) or CSV. Ensure that the delimiter and any special characters are correctly handled. You can use scripting languages like Python or shell scripts to automate this process.
With the ClickHouse client, use the `INSERT INTO` command to load your prepared data into the ClickHouse tables. For large datasets, consider using the `clickhouse-client` with the `--query` option to efficiently batch load data. Monitor the process to ensure that all data is correctly imported without errors.
After loading the data, perform a series of checks to verify data integrity and correctness. Run queries to ensure the data matches your expectations and check for any discrepancies. Additionally, test query performance to confirm that the data is indexed and structured efficiently for analytical operations.
By following these steps, you can successfully transfer data from AppFollow to a ClickHouse warehouse without relying on third-party connectors or integrations.
FAQs
What is ETL?
ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.
Appfollow is a one-stop platform for app analytics, app reviews management, and app store optimization. Get reviews from the App Store, Google Play to monitor and analyse them. AppFollow is on a mission to help teams working on mobile apps to turn insights from reviews into new product experiences that users love. Mobile teams are responding to feedback in a timely manner, building products they know users will love, and optimizing their performance in the app stores with AppFollow.
Appfollow's API provides access to a wide range of data related to mobile apps and their performance. The following are the categories of data that can be accessed through Appfollow's API:

What is ELT?
ELT, standing for Extract, Load, Transform, is a modern take on the traditional ETL data integration process. In ELT, data is first extracted from various sources, loaded directly into a data warehouse, and then transformed. This approach enhances data processing speed, analytical flexibility and autonomy.
Difference between ETL and ELT?
ETL and ELT are critical data integration strategies with key differences. ETL (Extract, Transform, Load) transforms data before loading, ideal for structured data. In contrast, ELT (Extract, Load, Transform) loads data before transformation, perfect for processing large, diverse data sets in modern data warehouses. ELT is becoming the new standard as it offers a lot more flexibility and autonomy to data analysts.
