Hi Helloway,

Now that’s a great way to start the discussion!!  Yes, I think certainly blobstore has a role in any SPDK solution that presents an object interface. Just to start with a basic question, your write up mentions some popular defacto standard interfaces for obj storage systems but then your high level blobkv if looks to be someone new & different. What are your thoughts on the external interface and tying into existing applications that support something like S3 or native Swift?

Thx
Paul

Hi all,
Thank you for your answers.
I have submitted the proposal about  the blobkv (blobstore object) design ( https://github.com/spdk/spdk/pull/188/files?short_path=420ca87#diff-420ca87f40f0f8170bb68bc5c742b6dc ), please visit it.

Hi,

Currently, SPDK can be integrated with Ceph in the following two ways:

1       SPDK has  rbd bdev,  thus you can have SPDK iSCSI target which uses the exported rbd device by Ceph.
2       SPDK  can be integrated into bluestore in Ceph, the code is NVMEDEVICE.CC/h, located in src/os/bluestore/ folder. However  SPDK is not enabled in Ceph. You need to build with WITH_SPDK=on option. And these days, we are doing some work to make SPDK can be compiled default in Ceph.

Also in SPDK for object store support,  we do not have a detailed plan now.

Best Regards,
Ziye Yang

Hi，
In the source code of SPDk (https://github.com/spdk/spdk/tree/master/lib), we can find spdk<https://github.com/spdk/spdk>/lib<https://github.com/spdk/spdk/tree/master/lib>/bdev<https://github.com/spdk/spdk/tree/master/lib/bdev>/ module that means  SPDk is able to be in favor of block store and accelerate ceph block store. However, I don not see anything about object store. Does SPDK support object store? Is there any plan to do with object store?



Could someone can give me the answer?

Regards,
Helloway
