well... I guess, I could use some generic class for all entities, so there
is only one class - *Item*, with "type" and "userId" attributes on each
node, ex:
- *User*("id":"123","name":"john",age:99) -> *Item*
("type":"user", "userId":"123", "name":"john",age:99)
- *Purchase*("id":"2222","userId":"123","price":100) -> *Item*
("type":"purchase", "purchaseId":"2222", "userId":"123", "price":100)
- *Account*("id":"11111","userId":"123","balance":10000) -> *Item*
("type":"account", "accountId":"11111", "userId":"123","balance":10000)
- etc.
in that case, I hope, it would be possible to implement custom sharding
strategy - based on attribute "userId" (all Items related to userId will be
placed in the same partition - user, purchases of that user, accounts of
that user, etc - that is what I'm looking for).
But following this approach I lose object-oriented features of OrientDb API
and custom types definition via schema, maybe I will loose something else
too, which I don't know about yet :(
maybe there is a better way to do such thing?
