If you're using https://khatru.nostr.technology/ and running strfry on the side you can now use https://pkg.go.dev/github.com/fiatjaf/eventstore/strfry as a compatible eventstore.

This allows you to, for example, have strfry be your main relay, but also expose other use-case specific relays on the side using strfry as your datasource -- or one of the data-sources --, you can easily add bluge search on top of strfry events without duplicating data, or, I don't know, query strfry data from a Go app for whatever purposes.
