How To Send Data From ClickHouse to Google Analytics 4

Are you looking to get more insights into your data? Integrating ClickHouse with Google Analytics 4 can help you achieve that. In this article, we'll guide you through the steps required to set up the integration and start sending data from ClickHouse to Google Analytics 4.

Understanding ClickHouse and Google Analytics 4

What is ClickHouse?

ClickHouse is a column-oriented database management system (similar to Google BigQuery, Amazon Redshift, and Snowflake) that is used for online analytical processing (OLAP), data warehousing, and business intelligence. Column-oriented means that ClickHouse stores data in columns as opposed to rows in relational databases such as PostgreSQL. This approach brings high performance and scalability, making it ideal for processing large volumes of data.

ClickHouse is an open-source project that was developed by Yandex, a Russian search engine company. It was designed to handle real-time analytics workloads and can process up to billions of rows of data per second. With its advanced compression algorithms and efficient query execution, ClickHouse is considered one of the fastest databases in the world. Popular use cases for ClickHouse are real-time dashboards, real-time analytics, business intelligence, data warehouse speed layer, logging & metrics, and ML & data science.

What is Google Analytics 4?

Google Analytics 4 is the latest version of Google Analytics. It provides a more comprehensive understanding of user behavior in cross-device and multi-channel environments when compared to its predecessor, Universal Analytics. It also includes advanced machine learning capabilities that can help you uncover insights that would be harder to find with traditional reporting.

Google Analytics 4 is built on a new data model that is designed to provide a more complete view of the customer journey. It uses events and parameters to capture user interactions across different devices and touchpoints. This allows you to track user behavior more accurately and get a better understanding of how users engage with your content.

Overall, the integration of ClickHouse with Google Analytics 4 can help you unlock the full potential of your data and gain deeper insights into user behavior. Whether you're a small business or a large enterprise, this powerful combination can help you make better decisions and drive growth.

Setting Up Your ClickHouse Environment

In this guide, we'll walk you through the process of installing and configuring ClickHouse, as well as creating a database and table to store the data you want to send to Google Analytics 4.

Installing ClickHouse

The first step in setting up the integration is to install ClickHouse. ClickHouse offers a cloud service where you don’t need to install and manage it on your own. But if you want to self-host the open-source version of ClickHouse, there are various ways to install depending on your operating system. For example, if you're using Linux, macOS, or FreeBSD, you can install ClickHouse via the following command:

SH
curl https://clickhouse.com/ | sh

Visit the official ClickHouse docs for detailed instructions on how to install ClickHouse.

Configuring ClickHouse

After installation, you need to configure ClickHouse to accept incoming connections and create a user account with the appropriate permissions. To create a user account with the appropriate permissions for a new database, you can use the following SQL code:

SQL
CREATE USER 'username' IDENTIFIED BY 'password';
CREATE DATABASE database_name;
GRANT ALL ON database_name.* TO 'username';

Creating a ClickHouse Database and Table

Now that ClickHouse is installed and configured, you'll need to create tables in ClickHouse to store the data you want to send to Google Analytics 4.

You can use the following SQL code to create a simple table:

SQL
CREATE TABLE clicks
(
user_id UUID,
event_time DateTime,
event_name String,
event_params Nested(
param_key String,
param_value String
)
) ENGINE = MergeTree()
ORDER BY event_time;

`MergeTree` is a table engine in ClickHouse designed to store large amounts of data. The above code creates a table called "clicks" with four columns: "user_id", "event_time", "event_name", and "event_params". The "event_params" column is a nested column that contains two sub-columns: "param_key" and "param_value". The table is also configured to use the MergeTree engine and order the data by the "event_time" column.

With your ClickHouse database and table set up, you're now ready to start sending data to Google Analytics 4.

Preparing Your Google Analytics 4 Account

In order to prepare your Google Analytics 4 account by following a few simple steps.

Creating a Google Analytics 4 Property

The first step in preparing your Google Analytics 4 account is to create a new property. This property will be used to receive the data you send from ClickHouse. To create a new property, simply navigate to the Google Analytics 4 admin page and click on the "Create Property" button. From there, you'll be prompted to enter some basic information about your website, such as the name and URL.

Once you've created your new property, you'll be provided with a unique tracking ID that you'll need to add to your website's code. This will allow Google Analytics 4 to start collecting data about your website's performance.

Setting Up Data Streams

After you've created your new property, you'll need to set up a data stream within that property. To set up a new data stream, simply navigate to the "Data Streams" section of your Google Analytics 4 admin page and click on the "Create Stream" button. From there, you'll be prompted to select the data source type and enter some basic information about your data stream.

Once you've set up your data stream, you'll be provided with a unique measurement ID that you'll need to add to your ClickHouse configuration. This will allow ClickHouse to start sending data to your Google Analytics 4 property.

Generating an API Key

Finally, you'll need to generate an API key that can be used to authenticate with the Google Analytics 4 API and send data from ClickHouse. To generate an API key, simply navigate to the "API & Services" section of your Google Cloud Console and click on the "Create Credentials" button. From there, you'll be prompted to select the type of credentials you want to create and enter some basic information about your project.

Once you've generated your API key, you'll need to add it to your ClickHouse configuration. This will allow us to authenticate with the Google Analytics 4 API and start sending data to your Google Analytics 4 property.

Connecting ClickHouse to Google Analytics 4

ClickHouse does not have direct integration or built-in functionality to send data from ClickHouse to Google Analytics 4. So in order to create the data pipelines from ClickHouse to GA4, you can either use external data integration tools (such as RudderStack) or you can create a custom script using GA4 APIs.

In this article, we will cover how to create your own custom script using GA4 API.

Extract Data from ClickHouse

The first job your script will do is to extract data from ClickHouse. You can use ClickHouse's client or HTTP interface to extract the data you want to send to GA4. In your command or script, you'll need to construct SQL queries that select the relevant data.

ClickHouse provides official clients to connect and query ClickHouse data in popular programming languages

Format Data to Map ClickHouse Data to Google Analytics 4 Metrics

Google Analytics 4 accepts data in a specific format, you can find the format in GA4 API’s reference docs. You'll need to transform the data you've extracted from ClickHouse into this format.

Use the GA4 API

Google Analytics 4 provides an API called Measurement Protocol that allows you to send data to GA4. You can find all the details about the Measurement Protocol here.

Authenticating Google Analytics 4 API

You'll also need to authenticate with the API, which generally involves creating a project in the Google Cloud Console, enabling the GA4 API for that project, and creating credentials that can be used to authenticate your requests. We have explained this in the previous section - “Preparing your Google Analytics 4 account”.

Schedule Your Script

If you want to send data from ClickHouse to GA4 on a regular basis, you'll need to run your data extraction, transformation, and loading script periodically. You could do this using a cron job or a similar scheduling system.

Handling failures

Considering the nature of data pipelines, failures are inevitable and must be effectively handled to ensure seamless operation. This could involve implementing error detection and alert mechanisms, automatic retries, and backup strategies. Regular audits of the pipeline and comprehensive logging can also help quickly identify and resolve issues. Tools such as Kafka can be used here to streamline the data processing and retry strategy workflows.

Please note that this is a generalized approach and you might need to adjust it according to your specific requirements and environment. You should refer to the ClickHouse and GA4 documentation for specific details on how to interact with them.

As an alternative, you can consider third-party data integration or Reverse ETL tools such as RudderStack to connect ClickHouse data with GA4.

Conclusion
