> Import scg-routing crate into Spark Connect Gateway
> ---------------------------------------------------

> Key: SPARK-58773
> URL: https://issues.apache.org/jira/browse/SPARK-58773
> Project: Spark
> Issue Type: Sub-task
> Components: Connect
> Affects Versions: connect-gateway-0.1.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh

>
> 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-routing crate — the routing core of the gateway. It defines
> the central traits and types that the pool and store layers implement and that
> the proxy routes through:
>
> - SessionKey — the routing key derived from a request
> - Pool — the backend-pool trait (implemented later by pool-static /
> pool-k8s)
> - AffinityStore — the session-affinity store trait (implemented later by
> store-memory / store-redis)
> - Router — ties them together
> scg-routing is a leaf crate (no internal dependencies), so it compiles and
> tests on its own. It is a prerequisite for the store, pool, healthcheck, and
> proxy crates that arrive in subsequent PRs.
