TL;DR
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:
- set up Redshift as a source connector (using Auth, or usually an API key)
- set up Databricks Lakehouse as a destination connector
- define which data you want to transfer and how frequently
You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.
This tutorial’s purpose is to show you how.

Method 2: Connecting Redshift to databricks lakehouse manually
Moving data from Amazon Redshift to Databricks Lakehouse can be achieved without third-party connectors by using a combination of native tools and services provided by AWS and Databricks. This guide assumes you have the necessary permissions in both environments and have installed the required CLI tools (AWS CLI, Databricks CLI).
Step 1: Export Data from Redshift to S3
1. Create an IAM Role for Redshift:
- Go to AWS IAM and create a new role.
- Attach policies that allow Redshift to access S3 (AmazonS3FullAccess or a more restrictive custom policy if needed).
- Attach this role to your Redshift cluster.
2. Create an S3 Bucket:
- Go to the AWS S3 service and create a new bucket to store the exported data.
3. Export Data from Redshift:
- Use the `UNLOAD` command in Redshift to export the data to the S3 bucket.
- Make sure to choose a suitable file format (CSV, AVRO, Parquet, etc.) for the exported data.
- Example SQL command:
```sql
UNLOAD ('SELECT * FROM your_table')
TO 's3://your-bucket-name/exported-data-prefix'
IAM_ROLE 'arn:aws:iam::your-account-id:role/your-redshift-role'
FORMAT AS PARQUET;
```
Step 2: Transfer Data from S3 to Databricks
1. Configure Databricks CLI:
- Install the Databricks CLI on your local machine.
- Configure it using the Databricks workspace token.
2. Mount the S3 Bucket to Databricks:
- Use Databricks to mount the S3 bucket as a DBFS (Databricks File System) mount point.
- Use the `dbutils.fs.mount` command in a Databricks notebook:
```python
dbutils.fs.mount(
source = "s3a://your-bucket-name",
mount_point = "/mnt/your-mount-point",
extra_configs = {"fs.s3a.access.key": "your-access-key", "fs.s3a.secret.key": "your-secret-key"}
)
```
Step 3: Import Data into Databricks Lakehouse
1. Create a Databricks Notebook:
- Create a new Databricks notebook to perform the data import.
2. Read Data from the Mounted S3 Bucket:
- Use the Databricks DataFrame API to read the data from the DBFS mount point.
- For example, if you exported the data in Parquet format:
```python
df = spark.read.parquet("/mnt/your-mount-point/exported-data-prefix")
```
3. Write Data to Databricks Lakehouse:
- Decide on the target location in Databricks Lakehouse (Delta Lake).
- Write the DataFrame to the Delta Lake using the DataFrame API.
- Example to write data as a Delta table:
```python
df.write.format("delta").save("/mnt/your-delta-table-path")
```
4. Create a Table:
- Optionally, you can create a table that references the Delta files.
- Use SQL commands in the Databricks notebook:
```sql
CREATE TABLE your_table_name
USING DELTA
LOCATION '/mnt/your-delta-table-path'
```
Step 4: Validate and Clean Up
1. Validate Data:
- Run queries against the new table or DataFrame to ensure the data has been transferred correctly.
- Compare record counts and sample data between Redshift and Databricks.
2. Unmount S3 Bucket (Optional):
- If you no longer need the S3 bucket mounted to Databricks, unmount it.
- Use the `dbutils.fs.unmount` command in a Databricks notebook:
```python
dbutils.fs.unmount("/mnt/your-mount-point")
```
3. Clean Up S3 Bucket:
- Remove the exported data from the S3 bucket if it's no longer needed.
Step 5: Schedule Data Refresh (Optional)
1. Automate Data Transfer:
- If you need to move data regularly, consider automating the process.
- Use AWS Data Pipeline, AWS Lambda, or other AWS services to schedule and run the Redshift `UNLOAD` command.
- Use Databricks Jobs to schedule data import into Databricks Lakehouse.
By following these steps, you can successfully transfer data from Amazon Redshift to Databricks Lakehouse without the need for third-party connectors or integrations. Always ensure that you are following best practices for security and data governance when transferring data between systems.
Use Cases to transfer your Redshift data to Databricks Lakehouse
Integrating data from Redshift to Databricks Lakehouse provides several benefits. Here are a few use cases:
- Advanced Analytics: Databricks Lakehouse’s powerful data processing capabilities enable you to perform complex queries and data analysis on your Redshift data, extracting insights that wouldn't be possible within Redshift alone.
