Worked on preparing HTTP-based remote rule evaluation in the grafana/mimir repository by refactoring the ruler.RemoteQuerier component. The approach involved replacing the existing gRPC-based client with an implementation using Go’s http.RoundTripper, aligning the transport layer with HTTP semantics. This change isolated transport concerns, improved modularity, and simplified future deployments by reducing coupling between components. The refactoring also enhanced testability, making it easier to adapt and extend remote rule evaluation features. Throughout the month, the focus remained on backend development, HTTP protocol adaptation, and code refactoring, with no major bug fixes recorded during this period of foundational engineering work.
