Hybrid data sharing systems hugely popular but …
well studied also?
In case of music share g and f might be realistically taken as:
CPU cost variations for chained architecture (batched and incremental)
Client-Server byte costs
Interserver byte costs
expected nr of results
No previous treatment of memory implications
Batch strategies better than the incremental counterparts
NumServers , Memory (for FR)
Mem of incremental=1/ActiveFrac Mem of batch
ActiveFrac incr. strategies come closer to batch.
Memory price may eliminate worries about memory limitations
