Guillermo, Phoenix by default puts columns into a CF named '_'. You can specify a different CF when creating tables or columns like this: mycf.col1, in which case Phoenix would put "col1" column into "mycf" CF, creating it if necessary. http://phoenix.apache.org/language/index.html#column_ref

I just started to discover Phoenix project. It looks pretty awesome.

I don't understand some points, When I create a table, how many are
CFs going to be created?, If I want to divide my data in two CF's, how
could I do it?
If I create a table from Phoenix, I guess that it's pretty hard to
query the table from native way, right?
Any scenario where it could be have more sense to use native-HBase than Phoenix?
