public interface QuerySource:

QuerySource

Internal non-generic execution boundary shared by KQL providers.

A provider receives a concrete typed plan through QueryPlanBase. The returned object is the concrete specialized result collection; this design avoids both generic virtual dispatch and per-element boxing.

rows = source.executePlan(plan)
