Re: How to handle secondary keys in partitioning?
Thanks.
Can you explain why it is a good idea to do sub-partitioning?
Even with the sub-partitioning, when I do "SELECT * FROM tp WHERE sender_id=1 ORDER BY date" MySQL would still need to read from 5 indexes and then merge sort, which is the same as when there is no sub-partitioning.
What are the advantages of sub-partitioning then?
Thanks.
