How to Sync to Manually

Step 1: Export Data from Google Directory

Begin by exporting the necessary data from Google Directory. You can use the Google Admin Console to create a data export. Go to the Admin Console, navigate to "Tools" -> "Data Export," and initiate an export. This process might take some time, and you will receive an email with a download link once the export is ready. The data will be in a downloadable format, typically as CSV files.

Step 2: Download the Exported Files

Once you receive the notification email, download the exported data files. These files will usually be in a compressed format such as ZIP. Extract the files to access the CSV data files that you will work with.

Step 3: Prepare the Data for Import

Open the CSV files and review the data to ensure it is clean and formatted correctly for ClickHouse. Check for any inconsistencies or formatting issues in the CSV files. Make any necessary modifications to ensure that the data types and structures align with your ClickHouse schema. Save the files after making these changes.

Step 4: Set Up ClickHouse Environment

Ensure that your ClickHouse server is up and running. Install ClickHouse on your server if it is not already installed. You can do this by following the ClickHouse installation documentation for your specific operating system. Once installed, start the ClickHouse server and ensure it is accessible.

Step 5: Define the ClickHouse Table Schema

Using the ClickHouse client, define the table schema that matches the structure of your CSV data. Connect to your ClickHouse server via the command-line client or a graphical interface, and use the `CREATE TABLE` SQL command to define your table structure. Ensure that the column names and data types align with those in your prepared CSV files.

Step 6: Transfer Data to ClickHouse

Use the ClickHouse `INSERT INTO ... FORMAT CSV` command to load your data into the defined table. For each CSV file, run a command like:
```sql
clickhouse-client --query="INSERT INTO your_table_name FORMAT CSV" < /path/to/your/csvfile.csv
```
Replace `your_table_name` with the name of your ClickHouse table and `/path/to/your/csvfile.csv` with the path to your CSV file. Repeat this process for each CSV file you need to import.

Step 7: Verify Data Integrity in ClickHouse

After loading the data, perform a series of checks to ensure that the data has been imported correctly. Run queries to count the number of records, check for data consistency, and ensure that no records are missing. Use SQL queries such as `SELECT COUNT(*) FROM your_table_name` and other relevant checks based on your data requirements.

By following these steps, you can successfully move data from Google Directory to a ClickHouse warehouse without relying on third-party connectors or integrations.
