Twitter comment:

"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"
