Partitions Cached


In Projections console (…/web/projections.htm) there is “Partitions Cached” indicator. I’m wondering is there any documentation on this property?

Few custom projections in our environment has ~3K partitions cached, while system projections are stable at 1.



They are .foreach projections or use .statePartitionedBy I assume?

Its the number of state variables for the folds.

Yes, .foreach is used in those projections.
Is this something I should be worried about or it should remain constant (assuming the state variables do not change)?

it means with foreach that you are running on 3k streams. There is a state per stream on a foreach
