Prerequisites

A IBM Db2 account to transfer your customer data automatically from.
A Clickhouse 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 IBM Db2 and Clickhouse, for seamless data migration.

When using Airbyte to move data from IBM Db2 to Clickhouse, it extracts data from IBM Db2 using the source connector, converts it into a format Clickhouse can ingest using the provided schema, and then loads it into Clickhouse via the destination connector. This allows businesses to leverage their IBM Db2 data for advanced analytics and insights within Clickhouse, simplifying the ETL process and saving significant time and resources.

Step 1: Set up IBM Db2 as a source connector

1. First, you need to obtain the necessary credentials to connect to your IBM Db2 source. This includes the hostname, port number, database name, username, and password.

2. Once you have the credentials, open the Airbyte platform and navigate to the "Sources" tab.

3. Click on the "Add Source" button and select "IBM Db2" from the list of available sources.

4. In the "Configure IBM Db2" page, enter the hostname, port number, database name, username, and password in the corresponding fields.

5. Click on the "Test Connection" button to ensure that the credentials are correct and that Airbyte can connect to your IBM Db2 source.

6. If the connection is successful, click on the "Save" button to save the configuration.

7. You can now create a new pipeline and select the IBM Db2 source as the origin. Follow the prompts to configure the pipeline and select the destination where you want to replicate the data.

8. Once the pipeline is set up, you can run it manually or schedule it to run at specific intervals.

9. You can monitor the progress of the pipeline and view any errors or warnings in the Airbyte platform.

10. Congratulations, you have successfully connected your IBM Db2 source to Airbyte and can now replicate your data to any destination of your choice.

Step 2: Set up Clickhouse as a destination connector

Step 3: Set up a connection to sync your IBM Db2 data to Clickhouse

FAQs

What is ETL?

ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.

What is IBM Db2?

What data can you extract from IBM Db2?

IBM Db2 provides access to a wide range of data types, including:

1. Relational data: This includes tables, views, and indexes that are organized in a relational database management system (RDBMS).

2. Non-relational data: This includes data that is not organized in a traditional RDBMS, such as NoSQL databases, JSON documents, and XML files.

3. Time-series data: This includes data that is collected over time and is typically used for analysis and forecasting, such as sensor data, financial data, and weather data.

4. Geospatial data: This includes data that is related to geographic locations, such as maps, satellite imagery, and GPS coordinates.

5. Graph data: This includes data that is organized in a graph structure, such as social networks, recommendation engines, and knowledge graphs.

6. Machine learning data: This includes data that is used to train machine learning models, such as labeled datasets, feature vectors, and model parameters.

Overall, IBM Db2's API provides access to a diverse range of data types, making it a powerful tool for data management and analysis.

How do I transfer data from IBM Db2?

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:
1. Set up IBM Db2 to ClickHouse as a source connector (using Auth, or usually an API key)
2. Choose a destination (more than 50 available destination databases, data warehouses or lakes) to sync data too and set it up as a destination connector
3. Define which data you want to transfer from IBM Db2 to ClickHouse and how frequently
You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.

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.
