Re: Move from unpartitioned database to partitioned database

[Mattias Jonsson]

First you must think of the reasons for adding partitioning. It is not a magic bullet, it has its pro's and con's.

1) ALTER TABLE t PARTITION BY .... That will partition your table by copying all data, like the general ALTER TABLE.
For more info, look at the manual:
http://dev.mysql.com/doc/refman/5.1/en/alter-table-partition-operations.html

2) -

3) If you thinking about range partitioning by date/auto increment, so yes. You can create an EVENT to do it for you.

4) The indexes is partitioned along with the data (so if you partition the table, also the indexes will be partitioned). So there is no need of rebuilding indexes after adding/dropping a partition.
