[ceph-users] multisite sync and multipart uploads

Hi guys, With Quincy release, does anyone know how multisite sync deals with multipart uploads? I mean those part objects of some incomplete multipart uploads. Are those objects also sync-ed over either with full-sync or incremental sync? I did a quick experiment and notice that these objects are not sync-ed over. Is it intentional or is there a defect of it? Thanks, Yixin
