bulkheads
fun bulkheads(bulkheads: (type: AggregateType, model: QueryModel) -> QueryBulkhead?): QueryEngine.Builder
The bulkhead of the store each aggregate type's model (snapshots or events) is queried on, one instance per store, null for none: the queries of every model on one store share it; for QueryModel.DATASET, the one the queries of the dataset of that name run under.
