Hm, so hypothetically an insert or update on a table with 4 indexes which have
been split into 4 partitions would need to touch each partition?
Would that defeat the benefits of the partitioning? Or enhance it?
Would it be better to ensure that the indexes of a single table ended up in
the same partition? Or to ensure they're spread across partitions?
