If you want to plug in a store into a DSL operator like aggregate, it
must be a key-value store as the aggregation is key-based (similar it
must be a windowed-store or session-store for window/session aggregation).
Not sure what code you wrote in 0.11 -- there, is must also be
key-value/window/ses
Is there an example code for this somewhere?
Also does it have to be key/value.
In my case a store is just a state, so key is not exposed.
It was working fine in the 11.0, but now semantics is very different

You can plug in a custom store via `Materialized` parameter that allows
to specify a custom `KeyValueBytesStoreSupplier` (and others)
