| CExecutorParamWriter | An ExecutorParamWriter is a ParamWriter whose scope is limited to a single executor node - it will never be serialized for transfer to a different node. As a result, any object which is allocated from a Vertica memory pool (i.e. a ServerInterface's allocator object) can have its address saved in the ExecutorParamWriter (see setPointer()), and be safely retrieved later on (see getPointer()) from a different API call in the same query |
| CExecutorPlanContext | An ExecutorPlanContext is a PlanContext object whose scope is limited to a single executor node: it and its parameters will never be serialized. In addition to providing information about nodes involved in a query, it indicates how many threads are available and allocated for a load |
