“Airbyte helped us accelerate our progress by years, compared to our competitors. We don’t need to worry about connectors and focus on creating value for our users instead of building infrastructure. That’s priceless. The time and energy saved allows us to disrupt and grow faster.”

"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."
Log into your Freshsales account and navigate to the desired modules (e.g., Contacts, Leads, Deals). Use the built-in export function to download the data as a CSV file. Ensure you select all necessary fields and apply any required filters to capture the relevant data set.
Open the exported CSV files using a spreadsheet application like Microsoft Excel or Google Sheets. Clean and format the data to match the schema you intend to use in ClickHouse. Ensure that there are no empty columns, and data types are consistent (e.g., dates, numbers).
Set up a ClickHouse server if not already done. Create a database and define tables that correspond to the data structure from Freshsales. Use the ClickHouse SQL console or a GUI tool to execute the necessary `CREATE TABLE` statements, specifying appropriate data types for each column.
Convert the cleaned CSV data into a format that can be ingested by ClickHouse. This typically involves ensuring the CSV conforms to the expected delimiters and data types. Use scripting languages like Python or Bash to automate the transformation process if needed.
Transfer the CSV files to the server where ClickHouse is hosted. This can be achieved using secure methods such as SCP (Secure Copy Protocol) or SFTP (Secure File Transfer Protocol). Ensure you have the necessary permissions and network access to the ClickHouse server.
Utilize the ClickHouse `clickhouse-client` command-line tool to import the CSV data into the ClickHouse tables. Execute a command such as `cat data.csv | clickhouse-client --query="INSERT INTO database.table FORMAT CSV"` to load the data. Verify that the data types and delimiters match the table schema.
Once the data is loaded, perform queries within ClickHouse to verify that the data has been imported correctly. Check for any discrepancies or errors in data types, missing values, or incorrect entries. Running aggregate functions and sample queries can help ensure the data integrity and accuracy.
By following these steps, you can successfully transfer data from Freshsales to a ClickHouse warehouse without the need for third-party connectors or integrations.

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.
