mvcc

Greetings Overflowers,

To my understanding (and I hope I'm not right) changes to indices cannot be MVCCed.
I'm wondering if this is also true with big records as copies can be costly.
Since records are accessed via indices (usually), how MVCC can be effective ?
Do, for e.g., indices keep track of different versions of MVCCed records ?

Any recent good reading on this subject ? Really appreciated !

Regards
