How to Sync to Manually

Step 1: Export Data from Pocket

Start by exporting your data from Pocket. Pocket provides options to export your saved items in formats such as JSON or HTML. Access your Pocket account, navigate to the export options, and download the data in your preferred format. This gives you a local file containing all your saved items and metadata.

Once you have the exported file, the next step is to ensure the data is in a format that is compatible with ClickHouse. If your data is in JSON or HTML, consider converting it to CSV or TSV format. You may use scripting languages like Python or command-line tools like `jq` (for JSON) to parse and convert the data into rows and columns suitable for ClickHouse.

If ClickHouse is not already installed, you need to set it up. You can download and install ClickHouse directly from their official website. Follow the installation instructions for your operating system. Once installed, start the ClickHouse server to ensure it is running and accessible.

Define the schema for your ClickHouse table that matches the structure of your data. Use the ClickHouse client to execute a `CREATE TABLE` statement. For example, if your data includes fields like `item_id`, `title`, `url`, and `tags`, create columns for each of these fields with appropriate data types.

With the table created, use the ClickHouse client to load your data. You can use the `INSERT INTO` statement to populate the table with data from your CSV or TSV file. ClickHouse provides the `clickhouse-client` tool which you can use to execute a command like:
```bash
clickhouse-client --query="INSERT INTO your_table FORMAT CSV" < your_data.csv
```
Ensure the column order in the CSV matches the table schema.

After loading the data, run queries to verify that the data has been imported correctly. Use simple `SELECT` statements to check for the expected number of rows, and spot-check a few records to ensure the data matches the source. This step helps identify any discrepancies or issues with the import process.

If you need to move data regularly, consider automating the process using scripts. Write a script in Bash, Python, or another language that performs these steps, from exporting from Pocket and converting the format to loading the data into ClickHouse. Schedule the script using a cron job or task scheduler to run at desired intervals.

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