Twitter評論：

    "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"
