> Performance chapter.
> book.xml
> * schema design chapter: moved the in-memory CF option, and bloom filter to
> the Peformance chapter's schema design section.
> * added link to performance chapter schema design section in Schema Design
> chapter.
> * added comment that online schema changes will be available in .92 (for an
> example where it shows a table being disabled for a CF change)
> performance.xml
> * added the in-memory CF option and bloom filter reference from book.xml (see
> above)
> * added sub-section on per-table regionsize configuration.
> * added subsection on blocksize configuration.
> * clarified entry on regionsizes and made it clear that large 20gb regions
> are only for HFile v2 format, whereas the largest HFile v1 format region is
> somewhere around 4gb.
