Certainly not in the near future, I'm afraid. It would require
allowing a single index to exist over multiple tables. There has been
discussions about this in the past and the general thoughts are that
if you have a single index over all partitions, then it massively
detracts from the advantages of partitioning. With partitioning, you
can DETACH or DROP a partition and get rid of all the data quickly in
a single metadata operation. If you have an index over all partitions
then that operation is no longer a metadata-only operation. It
suddenly needs to go and remove or invalidate all records pointing to
the partition you want to detach/drop.
