Hello,

Very helpful library Nikita.

I wonder what would be required to enable datascript to act more like a datomic 
peer, which holds, say, part of the db in browser memory, and then goes back to 
the server to fetch new segments if it can't serve the query from browser 
cache.  Older entries in the cache get gc'd and the system can operate on dbs 
of any size.

I realize this wasn't a design goal of datascript, and am just looking for 
insights into how it might be possible.  I guess a more fundamental question 
is: how does a datomic peer know when the segments to complete its query are 
not present in cache?  And can we emulate this in datascript?
