> Import scg-observability crate into Spark Connect Gateway
> ---------------------------------------------------------
>
> Key: SPARK-58930
> URL: https://issues.apache.org/jira/browse/SPARK-58930
> Project: Spark
> Issue Type: Sub-task
> Components: Connect
> Affects Versions: connect-gateway-0.1.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh
> Priority: Major
> Labels: pull-request-available
> Fix For: connect-gateway-0.1.0
>
>
> Part of importing the Spark Connect Gateway reference implementation into
> apache/spark-connect-gateway as a series of small, bottom-up PRs.
> This adds the scg-observability crate — the metrics, tracing, and admin
> surface
> for the gateway:
>
> - Prometheus metrics for the gateway
> - Distributed tracing — an OpenTelemetry exporter with W3C traceparent
> propagation
> - An admin HTTP server exposing /metrics, /healthz, and /readyz
>
> scg-observability is a leaf crate (no internal dependencies), so it compiles
> and
> tests on its own (8 unit tests). It is appended to the workspace members list,
> and is consumed later by the proxy and gateway crates.
