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.

- Select the data to sync: Choose the specific Snowflake objects you want to import data from towards Apache Iceberg. You can sync all data or select specific tables and fields.
- Select the sync mode for your streams: Choose between full refreshes or incremental syncs (with deduplication if you want), and this for all streams or at the stream level. Incremental is only available for streams that have a primary cursor.
- Test your connection: Click the 'Test Connection' button to make sure that your setup works. If the connection test is successful, save your configuration.
- Start the sync: If the test passes, click 'Set Up Connection'. Airbyte will start moving data from Snowflake to Apache Iceberg according to your settings.
Remember, Airbyte keeps your data in sync at the frequency you determine, ensuring your Apache Iceberg data warehouse is always up-to-date with your Snowflake data.
Method 2: Connecting Snowflake to apache iceberg manually
Moving data from Snowflake to Apache Iceberg without using third-party connectors or integrations involves several steps, including extracting data from Snowflake, transforming it into a compatible format for Apache Iceberg, and finally loading the data into an Iceberg table.
Here’s a step-by-step guide to accomplish this task:
Step 1: Prepare Your Apache Iceberg Environment
Before you start moving data, ensure that you have an Apache Iceberg environment set up and ready to receive data.
- Set Up a Hadoop/Spark Cluster: Apache Iceberg can integrate with compute engines like Spark. Make sure you have a Hadoop/Spark cluster running.
- Install Iceberg: Install Apache Iceberg on your Spark cluster. You can do this by adding Iceberg’s library to Spark’s classpath.
- Create an Iceberg Table: Define the schema and partitioning strategy for your Iceberg table, and create the table using Spark SQL or the Iceberg API.
Step 2: Extract Data from Snowflake
- Query Data: Write a SQL query to select the data you want to export from Snowflake.
- Export to CSV/JSON/Parquet: Use Snowflake’s data unloading capabilities to export the data into a file format that is compatible with Apache Iceberg, such as CSV, JSON, or Parquet. This can be done using the COPY INTO <location> command in Snowflake.
- Store the Data: Store the exported data files in a location accessible to your Spark cluster, such as Amazon S3, HDFS, or a local filesystem.
Step 3: Transform Data (If Required)
Depending on the format you’ve chosen to export data from Snowflake, you may need to transform it to match the schema of your Iceberg table.
- Read Data into Spark: Use Spark to read the data files into a DataFrame.
- Transform Data: Apply any necessary transformations to the DataFrame to match the schema and partitioning strategy of your Iceberg table.
- Write Data to Parquet (If Needed): If you’ve exported data in CSV or JSON format, convert it to Parquet, which is more efficient for Iceberg.
Step 4: Load Data into Apache Iceberg
- Write DataFrame to Iceberg: Use Spark’s DataFrameWriter API to write the DataFrame to the Iceberg table.
df.write
.format("iceberg")
.mode("append") // Use "overwrite" if you want to replace existing data
.save("path_to_your_iceberg_table")
- Refresh Table: After loading, refresh the Iceberg table to ensure that the metadata is updated and your data is visible.
Step 5: Validate Data Transfer
- Query Iceberg Table: Use Spark SQL to query the Iceberg table and validate that the data has been transferred correctly.
- Check Data Integrity: Compare the results of similar queries run on Snowflake and Iceberg to ensure data integrity.
Step 6: Clean Up
- Remove Temporary Files: If you created any temporary files or directories during the data transfer process, clean them up to prevent storage waste.
- Monitor Performance: Keep an eye on the performance of your Spark jobs and the Iceberg table. Adjust configurations as needed for optimal performance.
Step 7: Automate the Process (Optional)
Once you have successfully moved data manually, you might want to automate the process for recurring data transfers.
- Scripting: Write scripts to automate the export from Snowflake, transformation, and loading into Iceberg.
- Scheduling: Use a job scheduler like Apache Airflow, Oozie, or a cloud service equivalent to schedule the data transfer jobs.
Notes:
- Ensure that you have the necessary permissions to access both Snowflake and the storage used by Apache Iceberg.
- Be mindful of the data volume and network throughput, as transferring large datasets can be time-consuming and may incur costs.
- Consider incremental data loads if you are dealing with frequently updated datasets to optimize the data transfer process.
- Always test your data migration process with a subset of data before moving the entire dataset.
By following these steps, you can manually move data from Snowflake to Apache Iceberg without relying on third-party connectors or integrations.
Use Cases to transfer your Snowflake data to Apache Iceberg
Integrating data from Snowflake to Apache Iceberg provides several benefits. Here are a few use cases:
- Advanced Analytics: Apache Iceberg’s powerful data processing capabilities enable you to perform complex queries and data analysis on your Snowflake data, extracting insights that wouldn't be possible within Snowflake alone.
- Data Consolidation: If you're using multiple other sources along with Snowflake, syncing to Apache Iceberg allows you to centralize your data for a holistic view of your operations, and to set up a change data capture process so you never have any discrepancies in your data again.
- Historical Data Analysis: Snowflake has limits on historical data. Syncing data to Apache Iceberg allows for long-term data retention and analysis of historical trends over time.
- Data Security and Compliance: Apache Iceberg provides robust data security features. Syncing Snowflake data to Apache Iceberg ensures your data is secured and allows for advanced data governance and compliance management.
- Scalability: Apache Iceberg can handle large volumes of data without affecting performance, providing an ideal solution for growing businesses with expanding Snowflake data.
- Data Science and Machine Learning: By having Snowflake data in Apache Iceberg, you can apply machine learning models to your data for predictive analytics, customer segmentation, and more.
- Reporting and Visualization: While Snowflake provides reporting tools, data visualization tools like Tableau, PowerBI, Looker (Google Data Studio) can connect to Apache Iceberg, providing more advanced business intelligence options. If you have a Snowflake table that needs to be converted to a Apache Iceberg table, Airbyte can do that automatically.
