Sometimes I need to repeat creating and dropping indexes while doing
an SQL tuning work. As you might know, creating a large index takes
long time. So dropping the index and re-creating it is pain and
counter productive.
What about inventing a new SET command something like:
SET disabled_index to <index-name>
This adds <index-name> to "disabled index list". The disabled index
list let the planner to disregard the indexes in the list.
SET enabled_index to <index-name>
This removes <index-name> from the disabled index list.
SHOW disabled_index
This shows the content of the disabled index list.
Best regards,
