Hi,
I'm just browsing through the API documentations for Riak and I just
noticed a couple of things that's pretty confusing:
It's my understanding that with the HTTP fetch request, each
object/sibling returned will have its own vclock in the form of the HTTP
header `X-Riak-Vclock` and an entity tag under the header `ETag`. There
is also a vtag url parameter specified by the HTTP fetch request which I
assume fetches specific sibling with that entity tag. [1]
[1]:
http://docs.basho.com/riak/latest/references/apis/http/HTTP-Fetch-Object/
However, the protobuf client will return a list of siblings but only
with 1 vclock with `optional bytes vclock = 2;` for all the siblings
returned under `content`. For each sibling, there will be a `vtag`
attribute, which I assume is the entity tag as specified in the HTTP
document. [2]
[2]:
http://docs.basho.com/riak/latest/references/apis/protocol-buffers/PBC-Fetch-Object/
So the confusion is that why is it that in the HTTP request, each
sibling has its own vclock and entity tag/vtag while in the PBC request,
the entire response only has 1 vclock and each object has its own
vtag/entity tag. I'm not too sure if my understanding is complete.
Thanks,
Shuhao
