Comment 2 for bug 1229833

Dmitry,

We are aware of this problem. In fact, it is one of the major features we are going to work on next: https://blueprints.launchpad.net/percona-xtrabackup/+spec/lightweight-lock-backup

You are right, it requires some server-side support to be implemented properly. Once implemented, making XtraBackup support those lightweight locks would be trivial.

Closing the bug as invalid (as it duplicates an existing blueprint), but referencing it from the blueprint for the record.
