Can renaming a MySQL column be sped up by dropping indexes or foreign keys?

+3
−0

I need to rename one column in 170 tables in a MySQL database and its going really slow.

The columns all have an index plus a foreign key on them, would dropping the index/temporarily removing the foreign key speed up the process?

Can you show the code for renaming the column? If rename performane depends on the data volume, it sounds really strange (8063 explained why below).
