A Clojure library designed to ... well, that part is up to you.
|
||
|
|
|
||
|
|
|
||
|
|
## Design
|
||
|
|
|
||
|
|
Subscription
|
||
|
|
|
||
|
|
* subscribe to a view
|
||
|
|
* unsubscribe from a view
|
||
|
|
* remove all subscriptions (disconnect)
|
||
|
|
* get set of subscribed views
|
||
|
|
|
||
|
|
Deltas
|
||
|
|
|
||
|
|
* send deltas
|
||
|
|
* broadcast deltas
|
||
|
|
* receive deltas ( receive deltas from any other clients and broadcast out to subscribers a.k.a. broadcast deltas )
|
||
|
|
|
||
|
|
DB
|
||
|
|
|
||
|
|
* calculates pre-delta checks (heuristic optimization)
|
||
|
|
* calculates actual deltas
|
||
|
|
* different heuristics for inserts, updates, and deletes
|
||
|
|
* different properties for outer joins
|
||
|
|
* pre-checks and delta calculations are coupled:
|
||
|
|
- we don't know if we need to calculate insert deltas until we do the insert and see if the result affects a view
|
||
|
|
|
||
|
|
How should DB code work?
|
||
|
|
|
||
|
|
- separate namespaces for insert, update, delete?
|
||
|
|
- low-level db actions (execute/query/transaction/etc.) should be separate namespace?
|
||
|
|
- initial view computing (view map, args, etc.) should be separate namespace?
|
||
|
