"All engineering solutions are transient
Nothing's perfect but some solutions are good enough for a while
Scalability solutions aren't magic. They involve partitioning, indexing, and replication
All data for real-time queries MUST be in memory. Disk is for writes only.
Some problems can be solved with pre-computation, but a lot can't
Exploit locality where possible"
