Running SQLite directly from S3 with Turbolite

infrastructure

People talk about SQLite like it is just for small projects, but the real issue is the plumbing when you scale it for multiple tenants. Managing thousands of individual volumes is an operational nightmare; it looks fine in a diagram, but it is a mess to maintain in practice. Turbolite looks like a practical way out of that. It is a Rust-based VFS that lets the database run directly from S3-compatible storage. It uses page-level compression and encryption to hit sub-250ms cold latency, which basically turns S3 into the primary storage layer. This removes the need to babysit a massive amount of disk volumes. It would be worth evaluating how this handles heavy write loads compared to local disks, or if there are specific S3 providers where that latency starts to creep up.

The real story is that we are finally admitting the disk is a legacy abstraction. Why pretend we have local storage when the object store is the only thing that actually scales without breaking?

how does it handle write contention on a single s3 object?

It will likely lean on S3's strong consistency models for object updates. This could make it much easier to provide low-cost, dormant database hosting for users who only need their data accessed occasionally.

The sub-250ms cold latency claim needs nuance. SQLite typically requires multiple page reads to traverse the B-tree from the root to a leaf, so unless Turbolite implements aggressive speculative prefetching, the total time to first byte will be a multiple of the S3 request latency.

With the rise of Rust-based VFS projects like rencfs... does this mean we are moving toward a world where the concept of a server with attached block storage is obsolete... could we eventually boot entire stateful apps from S3?

That shift is necessary because managing EBS volume limits per instance is a constant headache in my environment. Getting rid of the need to provision and attach thousands of small disks saves hours of manual cleanup every month.
