[ceph-users] Question on multi-site

Hello - We're using libRADOS directly for our communication between services. Some of the features are faster and more featured for our use cases than an S3 gateway. But we do want to leverage the ES Metadata search. It appears that the Metadata search is built on the object gateway. Question is - do files which are written directly to an OSD get replicated using the gateway, or is it only files which are written through the gateway that get replicated? Thanks. Cary
