Hi, all Recently, I find out that when the instance with some metadata or system_metadata was deleted, but instance_metadata and instance_system_metadata these two tables are still keep the metadata and system_metadata deleted=0 (means these datas are not deleted). I am a little confused about this. Is this a bug or other somethings ? Thanks very much. 2012-11-01 hzyangtk -------------- next part -------------- An HTML attachment was scrubbed...
