Emily,

For now it is only in Percona-XtraDB, but it is not exclusive.
Everyone, including core, can implement it.

Is this coming to core, or is it exclusively percona?

Arjen, Shlomi,

What we show there is already available information in InnoDB data dictionary.
What you ask needs some additional changes in InnoDB data dict, which may be not easy to
archive (may break compatibility with current data dict), but it is hard to say, I did not look into yet.

Would you add “index_depth” column for indexes?

For both, can you add a column counting access?
This could then easily replace the server based table/index statistics and possibly in a more efficient manner.
