      TODO: The description needs to be updated based on this presentation.

       

      Implement a generic transport-based CE class that handles all logical nodes.
      This class also handles in a generic way:

      • Estimation of conjunctions/disjunctions inside SargableNode.
      • Estimation of SARGable elemMatch Filter nodes.
      • In the future it will handle complex FilterNodes.

      Each transport method for each node type will take into account whether a specific estimation method is enabled, and call the corresponding estimation logic for each atomic interval or predicate. In the case of histogram-based estimation, the method will also check for and fetch the histogram for the filtered path, and will call histogram-based estimation.
