Question

is there a canonical way to partition a table by referenced data to another table?

for example

timetable
   id
   datetime

bigtable
   id
   timetable_id -- foreign key
   .. other data ..

i want to partition bigtable by the datetime in timetable. thankx.

Answer 1

As noted here, he partitioning column must be a part of all unique indexes on the table, which would include your primary key.

I think your only choice here would be to denormalize the timetable.datetime column into bigtable so that the column is available for partitioning.
