Hi,
Stretch clusters[0] are new in Pacific; does anyone have experience of
using one in production?
I ask because I'm thinking about new RGW cluster (split across two main
DCs), which I would naturally be doing using RGW multi-site between two
clusters.
But it strikes me that a stretch cluster might be simpler (multi-site
RGW isn't entirely straightforward e.g. round resharding), and 2 copies
per site is quite a bit less storage than 3 per site. But I'm not sure
if this new feature is considered production-deployment-ready
Also, if I'm using RGWs, will they do the right thing location-wise?
i.e. DC A RGWs will talk to DC A OSDs wherever possible?
Thanks,
Matthew
