class ResolverRunner extends ResolverMetricTracker with SQLConfHelper
Wrapper class for Resolver and single-pass resolution. This class encapsulates single-pass resolution, rewriting and validation of resolved plan. The plan rewrite is necessary in order to either fully resolve the plan or stay compatible with the fixed-point analyzer.

- def recordTopLevelMetrics[R](tracker: QueryPlanningTracker)(body: => R): R
Log top-level timing metrics for single-pass analyzer.
Log top-level timing metrics for single-pass analyzer. In order to utilize existing logging infrastructure, we are going to log single-pass metrics as if single pass resolver was a standalone Catalyst rule. We log every run of single-pass resolver as effective.

- def resolve(plan: LogicalPlan, analyzerBridgeState: Option[AnalyzerBridgeState] = None, tracker: QueryPlanningTracker = new QueryPlanningTracker): LogicalPlan
Entry point for the resolver.
Entry point for the resolver. This method performs following 4 steps:
- Resolves the plan in a bottom-up using Resolver, single-pass manner.
- Rewrites the plan using rules configured in the planRewriter.
- Validates the final result internally using ResolutionValidator.
- Validates the final result using extendedResolutionChecks.
