Mysql - How can I replication structure, not data
The blackhole engine type will work for what I need.  We are using row based replication and can't change to statement based but the warnings are not being logged so that won't be an issue.  

As a side note, one thing I found somewhere suggested show variables like 'have_blackhole_engine' and nothing came up (nor for show variables like '%blackhole%' or show global variables like '%blackhole%') but I decided to create a table with the engine and it showed up just fine.
