  Description copied from interface: AggregationStateFactory
  
  Produces a MemoKey for this aggregation state factory.
  If two AggregationStateFactories have equal memoKeys, then Table.by(com.illumon.iris.db.v2.by.AggregationStateFactory, com.illumon.iris.db.v2.select.SelectColumn...) operations that have the same group by columns may be memoized. In that case instead of recomputing the result; the original result will be used.
  
  If null is returned, the operation will not be memoized.
  
  Specified by:
  
  getMemoKey in interface AggregationStateFactory
  
  Returns:
  
  an AggregationMemoKey, null if this operation can not be memoized.
