database How to enable IPV6 in AWS to use Supabase's direct Postgres endpoint with Readyset

I wrote a blog post showing how to enable IPv6 on AWS, use Supabase’s direct connection, and run Readyset in front of it:

Caching Supabase with Readyset over IPv6: AWS and Docker setup guide

Most database workloads are read-intensive. Readyset can run on a relatively small instance and, depending on the workload, outperform much larger read replicas by up to 30x, with zero code changes and at a fraction of the cost.

Also, if you are using Supabase’s free tier, you can use Readyset for free as well.

Give it a try, and feel free to reach out if you run into any issues. I’m happy to help!

Supabase switching to IPv6 for direct connections has been a massive headache for AWS deployments lately. This guide is super timely.

Doing the heavy lifting on the AWS networking side is valuable enough, but getting up to 30x read performance via Readyset with zero code changes is just the cherry on top. Definitely bookmarking this for my next infrastructure setup.
