+//typesafe is a shitload more work that we can avoid
+//
+//The Event base implementaiton could take a pointer to a single property mapper,
+//and a void pointer to the mmapped region. => event is copyable and stack allocatable and we avoid large amounts of heap allocated objects
+//-The mapper should in this case live in the other thread
+//-default property mapper implementation can answer "is property X supported?"
+//-how do we free/munmap the data if we don't know when no one references it any longer? => no munmap needed, but read transaction to keep pointer alive
+//-we could bind the lifetime to the query
+//=> perhaps do heap allocate and use smart pointer?
