How to bind D1 databases dynamically

[luozhouyang]

I want to build a SaaS application where each tenant has their own d1 database instances. The question is workers' bindings are configured on wrangler.toml statically, is there any way to bind these d1 database instances dynamically so that I can dispatch request to tenant's own database dynamically.

The only way at the moment is to use the Workers API (https://developers.cloudflare.com/api/resources/workers/subresources/scripts/methods/update/) with a new worker configuration with the updated D1 bindings.

We have some plans to make it easier, but no concrete ETAs yet.
