Redshift Export

Using the Redshift Export app requires either PostHog Cloud, or a self-hosted PostHog instance running version 1.30.0 or later.

Not running 1.30.0? Find out how to update your self-hosted PostHog deployment!

You'll also need access to a Redshift Cluster to export to.

Installation

Create a Redshift Cluster
Make sure PostHog can access your cluster

This might require a few things:

Allowing public access to the cluster
Ensuring your VPC security group allows traffic to and from the Redshift cluster - If this is not possible in your case, you should consider using our S3 Export app and then setting up your own system for getting data into your Redshift cluster

Create a user with table creation privileges

We need to create a new table to store events and execute INSERT queries. You can and should block us from doing anything else on any other tables. Giving us table creation permissions should be enough to ensure this:

SQL

CREATE USER posthog WITH PASSWORD '123456yZ';
GRANT CREATE ON DATABASE your_database TO posthog;

Add the connection details at the configuration step in PostHog
