# See http://doc.gitlab.com/ce/development/migration_style_guide.html

# Set this constant to true if this migration requires downtime.
DOWNTIME = false
# When a migration requires downtime you **must** uncomment the following
# constant and define a short and easy to understand explanation as to why the
# migration requires downtime.
# DOWNTIME_REASON = ''
# When using the methods "add_concurrent_index" or "add_column_with_default"
# you must disable the use of transactions as these methods can not run in an
# existing transaction. When using "add_concurrent_index" make sure that this
# method is the _only_ method called in the migration, any other changes
# should go in a separate migration. This ensures that upon failure _only_ the
# index creation fails and can be retried or reverted easily.
#
# To disable transactions uncomment the following line and remove these
# comments:
# disable_ddl_transaction!
