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.
