> Secondary indexes flush when the parent does. This has an unfortunate side
> effect: a single CF flushing with a single secondary index fills the flush
> queue and blocks further writes until the first one completes. A simple but
> naive optimization here would be to queue the indexes before the parent since
> they are generally going to be smaller, and thus flush faster, reducing the
> amount of time writes are blocked.
