getMemoKey

public AggregationMemoKey getMemoKey()

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.
