Method row_desc

be/src/exec/exec-node.h:298–298

Returns the row descriptor for rows produced by this node. The RowDescriptor is constant for the lifetime of the fragment instance, and so is shared by reference across the plan tree, including in RowBatches. The lifetime of the descriptor is the same as the lifetime of this node.
