Hi Joe, I'm currently looking at the radosgw-agent, and i have seen your recent job on full sync of data. What will be the preferred way to list all objects to sync? Using admin API or standard S3 API?
It looks like we'll use the S3 API to list the objects in a bucket (we'll actually use the boto library to do this). It's worth noting that there's some locking that we need to do to account for multiple agents running at the same time, so it's not quite as easy as "list objects, sync objects, call it a day".
Moreover, we will need to do an exact copy of the object to preserve attributes, as mentionned here http://pad.ceph.com/p/rgw-multi-region-dr . Will this be part of the admin API? or am i missing something?
The following link on the wiki has most (all?) of the calls that are being added for the sync work. There's an extended object GET and PUT in there, towards the top. http://wiki.ceph.com/index.php?title=RESTful_API_for_DR_%2F%2F_Geo-Replication This link is also handy in terms of an overview: http://www.spinics.net/lists/ceph-devel/msg11905.html
Btw i recently posted an article here :http://blog.kri5.fr/?p=21, to setup two cluster for testing purpose of the radosgw-agent.
Cool.
Best regards.
