TL;DR
This can be done by building a data pipeline manually, usually a Python script (you can leverage a tool as Apache Airflow for this). This process can take more than a full week of development. Or it can be done in minutes on Airbyte in three easy steps:
- set up ClickHouse as a source connector (using Auth, or usually an API key)
- set up JSON File Destination as a destination connector
- define which data you want to transfer and how frequently
You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.
This tutorial’s purpose is to show you how.
What is ClickHouse
An open-source database management system for online analytical processing (OLAP), ClickHouse takes the innovative approach of using a column-based database. It is easy to use right out of the box and is touted as being hardware efficient, extremely reliable, linearly scalable, and “blazing fast”—between 100-1,000x faster than traditional databases that write rows of data to the disk—allowing analytical data reports to be generated in real-time.
What is JSON File Destination
JSON File is a tool that is used to store and exchange data in a structured format. JSON stands for JavaScript Object Notation, and it is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. JSON files are commonly used in web applications to transfer data between the server and the client, and they are also used in many other programming languages and platforms. JSON files consist of key-value pairs, where each key is a string and each value can be a string, number, boolean, array, or another JSON object. The syntax of JSON is similar to that of JavaScript, but it is a separate language that can be used independently of JavaScript. JSON File is a tool that allows users to create, edit, and view JSON files. It provides a user-friendly interface for working with JSON data, and it can be used by developers, data analysts, and anyone else who needs to work with structured data. With JSON File, users can easily create and modify JSON files, and they can also validate the syntax of their JSON data to ensure that it is well-formed and error-free.
Prerequisites
- A ClickHouse account to transfer your customer data automatically from.
- A JSON File Destination account.
- An active Airbyte Cloud account, or you can also choose to use Airbyte Open Source locally. You can follow the instructions to set up Airbyte on your system using docker-compose.
Airbyte is an open-source data integration platform that consolidates and streamlines the process of extracting and loading data from multiple data sources to data warehouses. It offers pre-built connectors, including ClickHouse and JSON File Destination, for seamless data migration.
When using Airbyte to move data from ClickHouse to JSON File Destination, it extracts data from ClickHouse using the source connector, converts it into a format JSON File Destination can ingest using the provided schema, and then loads it into JSON File Destination via the destination connector. This allows businesses to leverage their ClickHouse data for advanced analytics and insights within JSON File Destination, simplifying the ETL process and saving significant time and resources.
Step 1: Set up ClickHouse as a source connector
1. First, navigate to the Airbyte dashboard and click on the "Destinations" tab on the left-hand side of the screen.
2. Next, click on the "Add Destination" button in the top right corner of the screen.
3. Select "ClickHouse" from the list of available destinations.
4. Enter the necessary information for your ClickHouse database, including the host, port, username, and password.
5. Choose the database and table you want to connect to from the dropdown menus.
6. Configure any additional settings, such as the batch size or maximum number of retries.
7. Test the connection to ensure that everything is working properly.
8. Once you have successfully connected to your ClickHouse database, you can begin syncing data from your source connectors to your ClickHouse destination.
Step 2: Set up JSON File Destination as a destination connector
1. Open the Airbyte platform and navigate to the "Destinations" tab on the left-hand side of the screen.
2. Scroll down until you find the "JSON File" destination connector and click on it.
3. Click on the "Create new connection" button.
4. Enter a name for your connection and click on the "Next" button.
5. Fill in the required fields for your JSON File destination, such as the file path and format.
6. Test the connection by clicking on the "Test" button.
7. If the test is successful, click on the "Save & Sync" button to save your connection and start syncing data to your JSON File destination.
8. You can also schedule your syncs by clicking on the "Schedule" button and selecting the frequency and time for your syncs.
9. To view your synced data, navigate to the file path you specified in your JSON File destination and open the file in a text editor or JSON viewer.
Step 3: Set up a connection to sync your ClickHouse data to JSON File Destination
Once you've successfully connected ClickHouse as a data source and JSON File Destination as a destination in Airbyte, you can set up a data pipeline between them with the following steps:
- Create a new connection: On the Airbyte dashboard, navigate to the 'Connections' tab and click the '+ New Connection' button.
- Choose your source: Select ClickHouse from the dropdown list of your configured sources.
- Select your destination: Choose JSON File Destination from the dropdown list of your configured destinations.
- Configure your sync: Define the frequency of your data syncs based on your business needs. Airbyte allows both manual and automatic scheduling for your data refreshes.
- Select the data to sync: Choose the specific ClickHouse objects you want to import data from towards JSON File Destination. You can sync all data or select specific tables and fields.
- Select the sync mode for your streams: Choose between full refreshes or incremental syncs (with deduplication if you want), and this for all streams or at the stream level. Incremental is only available for streams that have a primary cursor.
- Test your connection: Click the 'Test Connection' button to make sure that your setup works. If the connection test is successful, save your configuration.
- Start the sync: If the test passes, click 'Set Up Connection'. Airbyte will start moving data from ClickHouse to JSON File Destination according to your settings.
Remember, Airbyte keeps your data in sync at the frequency you determine, ensuring your JSON File Destination data warehouse is always up-to-date with your ClickHouse data.
Use Cases to transfer your ClickHouse data to JSON File Destination
Integrating data from ClickHouse to JSON File Destination provides several benefits. Here are a few use cases:
- Advanced Analytics: JSON File Destination’s powerful data processing capabilities enable you to perform complex queries and data analysis on your ClickHouse data, extracting insights that wouldn't be possible within ClickHouse alone.
- Data Consolidation: If you're using multiple other sources along with ClickHouse, syncing to JSON File Destination allows you to centralize your data for a holistic view of your operations, and to set up a change data capture process so you never have any discrepancies in your data again.
- Historical Data Analysis: ClickHouse has limits on historical data. Syncing data to JSON File Destination allows for long-term data retention and analysis of historical trends over time.
- Data Security and Compliance: JSON File Destination provides robust data security features. Syncing ClickHouse data to JSON File Destination ensures your data is secured and allows for advanced data governance and compliance management.
- Scalability: JSON File Destination can handle large volumes of data without affecting performance, providing an ideal solution for growing businesses with expanding ClickHouse data.
- Data Science and Machine Learning: By having ClickHouse data in JSON File Destination, you can apply machine learning models to your data for predictive analytics, customer segmentation, and more.
- Reporting and Visualization: While ClickHouse provides reporting tools, data visualization tools like Tableau, PowerBI, Looker (Google Data Studio) can connect to JSON File Destination, providing more advanced business intelligence options. If you have a ClickHouse table that needs to be converted to a JSON File Destination table, Airbyte can do that automatically.
Wrapping Up
To summarize, this tutorial has shown you how to:
- Configure a ClickHouse account as an Airbyte data source connector.
- Configure JSON File Destination as a data destination connector.
- Create an Airbyte data pipeline that will automatically be moving data directly from ClickHouse to JSON File Destination after you set a schedule
