Document layer stores a field under single key in FDB. So, we are limited by FDB value size (100K). By splitting it across multiple FDB keys we can support bigger fields.

Potential design

DataValue defines the type of value. Other than all the normal types, we also have arrays and objects. We could have another type, ex: SPLIT_VALUE, and this could just piggyback on arrays code. We have to change the code in insert and updates, which assume values are always stored under a single key. Path expansion should not treat split key component as part of the key. So, array expansion rules should be carefully adjusted to work with this.
