## cascading.tuple.collect
Class SpillableTupleList

    java.lang.Object
      cascading.tuple.collect.SpillableTupleList

All Implemented Interfaces:
  Spillable, Iterable<Tuple>, Collection<Tuple>

Direct Known Subclasses:
  HadoopSpillableTupleList

    public abstract class SpillableTupleList

extends Object
implements Collection<Tuple>, Spillable

Class SpillableTupleList is a simple durable Collection that can spill its contents to disk when the `threshold` is met.

Using a `threshold` of -1 will disable the spill, all values will remain in memory. This class is used by the `CoGroup` pipe, to set properties specific to a given CoGroup instance, see the `Pipe.getConfigDef()` method.

Use the `SpillableProps` fluent helper class to set properties.
