To simplify testing, deployment and delivery the server uses SQLite as a database backend. It obviously locks server into single instance.
To scale it into multiple instances SQLite should be replaced by any RDBMS supporting network access.
It can be easily done by changing DSN and dialect parameters in config file.
To reproduce benchmark run go test -bench=. -benchmem inside toto-config/pkg/apiserver/models first. It will generate random data and stores it into /tmp/models-test.db which will be reused. (NOTE: no clean up here, the part of testing.Main which is in charge of cleanup is commented).
Expected output:
2022/12/05 13:19:39 goose: no migrations to run. current version: 1
