However be prepared to rethink your indexing strategies.

Thanks Chris.
I didn't understand by what do you mean by "be prepared to rethink your indexing strategies."

In MySQL, I have created indexes, Unique indexes, complex or multi-field indexes, etc.
In what way should I re-consider the indexing?

Thanks,
Vineet
