A new topic, 'Alter table performance', has been made on a board you are
watching.
You can see it at
http://liquibase.org/forum/index.php?topic=581.new#new
The text of the topic is shown below:
At work we have a big problem that makes at some degree standard alter table
changesets unusable.
The problem is that all alter table MySQL statements made a temporal
duplication of the table and when ran in a big table can take an hour for
example. This is an inherent problem of MySQL but the big problem we have for
liquibase if that if we need to add ten new columns then the time is ten hours.
More people suffer from that lack of ability to group alter table statements?
Has never evaluated or studied for newer versions? Or has some workarround that
preserves database independency?
A lot of thanks in advance,
