Predictable, straightforward pricing model that simplified budgeting and significantly reduced overall spend

Chase Zieman

“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.”

Rupak Patel
"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."
How to Sync to Manually
Step 1: Export Data from PostHog
First, you need to extract the data from PostHog. Use PostHog's API to export the data. Make an API call to the relevant endpoint, such as `/api/events/`, to retrieve the event data. Ensure you have the necessary API keys and permissions to access the data. You might need to script this step using a language like Python to handle pagination and large datasets.
Step 2: Transform Data Locally
After exporting the data, you might need to transform it into a format suitable for AWS S3. Use a local environment to convert the data into a CSV or JSON format, which are commonly used in S3. Ensure that your data is clean, removing any unnecessary fields or correcting any data inconsistencies.
Step 3: Set Up AWS S3 Bucket
Log into your AWS Management Console and navigate to S3. Create a new S3 bucket if you don’t have one already. Note the name of the bucket and the region, as you will need this information for uploading the data. Ensure that the bucket has the proper permissions set up to allow data upload.
Step 4: Upload Data to S3
Use the AWS CLI or an SDK (such as Boto3 for Python) to upload your transformed data file to the S3 bucket. The command for AWS CLI is `aws s3 cp your_data_file.json s3://your-bucket-name/`. Ensure that your IAM role or user has the necessary permissions to perform this action.
Step 5: Prepare AWS Glue for Data Crawling
In the AWS Management Console, navigate to AWS Glue. Set up a Glue Crawler by defining a data source (your S3 bucket), and configure it to create or update a database and tables within Glue. This will allow Glue to understand the structure of your data.
Step 6: Run the Glue Crawler
Execute the Glue Crawler to scan the data in your S3 bucket. The crawler will infer the schema of your data and create the necessary tables in the Glue Data Catalog. This process might take some time, depending on the size of your data.
Step 7: Create and Run Glue ETL Jobs
With the data cataloged, create an ETL job in AWS Glue to transform, enrich, or aggregate your data as required. Use the Glue Studio or write PySpark scripts to define your ETL logic. Once your job is configured, run it to process the data and output the results to another S3 bucket or data store.
This guide provides a framework for manually moving data from PostHog to AWS S3 and using Glue without third-party connectors. Adjust the steps according to your specific requirements and data structure.
