adding compression to a table

Can I add record level compression to a preexisting table?  Will old 
rows be compressed or only new rows?

For example, if I use the hbase shell and disable, alter {...COMPRESSION 
=> 'gz'....}, enable....  Do I need to run a compaction as well?

Or do I need to create a new table?

Justin,

You don't need to explicitly call a compaction, conversion will be
done over time. But if you do want to have them converted right away,
call a major_compaction.
