# you must disable the use of transactions

2017-08-17 22:00:37 +05:30

# When using "add_concurrent_index" or "remove_concurrent_index" methods make sure
|
|
|
|
|
# that either of them 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 or removing fails

|
|
|
# and can be retried or reverted easily.
