Re: How are indexes partitioned on a partitioned table

Currently, all MySQL partitioned indexes are similar to Oracle local indexes.
As of 5.1.24 there is not concept of Global indexes that I know of.

If you have a table partitioned by month, and create an index on that table,
it will effectively be partitioned by month as well.

There are some constraints/limitations with respect to MySQL partitioning
that you should look at coming from Oracle:

http://dev.mysql.com/doc/refman/5.1/en/partitioning-limitations.html

Specifically things pertaining to foreign keys not allowed, most partition
types require integers for key(s), etc. There are also some differences as
far as how maint works from an 'online' perspective.

They do, however, work quite well...
