Node example demonstrating the tail of a table using dask.



**Documentation**

This example shows a basic version of tail, implemented using dask.
Tail produces a new table similar to *Slice data Table* with
*1:* as the slice expression.

Dask nodes have biggest effect in locked subflows and lambdas where
data between nodes is passed in memory.


**Definition**


*Input ports*

    :input:  table

        Input Table


*Output ports*

    :output:  table

        Output Table
