Re: mysql - How much disk space is used by indexes?

To be consistent one must implement a database space management system for which the source data are database which have database maintenance plans already automated (or at least run routinely).

Database maintenance plans should be therefore implemented, and the index/data useage stats examined after these maintenance plans are done.

ie: What you are looking at might simply be lack of database reoganisation task scheduling.
