Fairly new to ceph so please excuse any misused terminology. We’re currently exploring the use of ceph as a replacement storage backend for an existing application. The existing application has 2 requirements which seemingly can be met
individually by using librados and the Ceph Object Gateway multisite support, but it seems cannot be met together. These are: 1.
The ability to append to an existing object and read from any offset/length within the object, (the librados API allows this, the S3 and Swift APIs do not appear to support this). 2.
The ability to replicate data between 2 geographically separate locations. I.e. 2 separate ceph clusters using the multisite support of the Ceph Object Gateway to replicate between them. Specifically we’re testing using librados to write directly to the object store because we need the ability to append to objects, which using the librados API allows. However if one writes to the object store directly using the librados
API is it correct to assume that those objects will not be replicated to the other zone by the Ceph Object Gateway since its being taken out of the data path?
