Would this be vulnerable to a side-channel attack as follows?
1. Record what item was retrieved from disk for a query
2. Run a dictionary through the query system, and see which item matches the record

- blintz 4y agoThe server processing has to scan the entire database to answer a query- so the entire database stays in memory, and access patterns tell you nothing about the query.
- gojomo 4y agoNotably to some who may misinterpret the "stays in memory" aspect: even the copy in memory is fully scanned by every query. So it's not just disk access patterns that don't give anything away, but RAM access patterns.
