== On the number of column families
HBase currently does not do well with anything above two or three column
families so keep the number of column families in your schema low.
-Currently, flushing and compactions are done on a per Region basis so if one
column family is carrying the bulk of the data bringing on flushes, the
adjacent families will also be flushed even though the amount of data they
carry is small.
-When many column families exist the flushing and compaction interaction can
make for a bunch of needless i/o (To be addressed by changing flushing and
compaction to work on a per column family basis). For more information on
compactions, see <<compaction>>.
