> The current indexed-edit-distance-join plan uses REPLICATE operator to
> propagate the incoming frames to all branches and T value in the
> T-occurrence problem is calculated twice for the same tuple. These
> redundancies can be resolved using SPLIT operator. Refer to the following doc
> for more details.
