Observability

[fnikolai]

• On services that expose HTTP endpoints, print the meta-prefix, if used. For example, in the following tables, assuming --meta-prefix=/rest the paths should be: /rest/docs, /rest/db/show, etc.

• Add an sanitizer of connection string for Snowflake. If the user omits the schema, superduper will fail, someimes due to ibis, and sometimes due to sqlaclemy.

• Use correct error codes on REST server. For instance, this one seems like a 400 (Bad Request) than a 500 (Internal Server error)
