CockroachDB Cluster API

REST API hosted by every CockroachDB node under the /api/v2 base path, exposed on the same HTTP port as the DB Console (default 8080). Provides health checks, node detail, hot range info, session and query introspection, database and table metadata, and event log retrieval. Authentication uses session tokens obtained via /api/v2/login/ and passed in the X-Cockroach-API-Session header.
