>From my understanding, if I implement my own state factory to use in
PersistentAggregate, the grouping fields will be the key values in the
state,
However, if I want to have access to other fields in the aggregation, how
might I get those ? From my understanding, doing a groupBy() will create a
new GroupedStream which will only have the fields specified in the
groupBy().
Essentially what I want to do is:
stream
.groupBy(new Fields("a"))
.persistentAggregate(
new Factory(),
new Fields("b"),
...
)
How would I do this ?
