Following feedback at the Portland summit, the work is initially limited to dispersal at the container level, i.e. each container within an account may be stored on a different cluster, whereas every object within a container will be stored on the same cluster.”</span><span lang="EN-US"><o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN" style="font-size: 9pt; font-family: Arial, sans-serif; color: rgb(51, 51, 51); "> </span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN" style="font-size: 9pt; font-family: Arial, sans-serif; color: rgb(51, 51, 51); ">It is<span class="Apple-converted-space"> </span><b>work in progress</b>, but we’d welcome feedback on this thread, or in person for anyone who might be at the hackathon in Austin next week.<o:p></o:p></span></div><p style="margin-right: 0cm; margin-bottom: 9.6pt; margin-left: 0cm; font-size: 12pt; font-family: 'Times New Roman', serif; line-height: 13.5pt; "><span lang="EN" style="font-size: 9pt; font-family: Arial, sans-serif; color: rgb(51, 51, 51); ">The bulk of the new features are in this patch:<span class="Apple-converted-space"> </span><br><a href="https://review.openstack.org/51236" style="color: purple; text-decoration: underline; ">https://review.openstack.org/51236</a><span class="Apple-converted-space"> </span>(Middleware module for container forwarding.)<o:p></o:p></span></p><p style="margin-right: 0cm; margin-bottom: 9.6pt; margin-left: 0cm; font-size: 12pt; font-family: 'Times New Roman', serif; line-height: 13.5pt; "><span lang="EN" style="font-size: 9pt; font-family: Arial, sans-serif; color: rgb(51, 51, 51); ">There’s a couple of patches refactoring/adding support to existing modules:<br><a href="https://review.openstack.org/51242" style="color: purple; text-decoration: underline; ">https://review.openstack.org/51242</a><span class="Apple-converted-space"> </span>(Refactor proxy/controllers obj & base http code)<br><a href="https://review.openstack.org/51228" style="color: purple; text-decoration: underline; ">https://review.openstack.org/51228</a><span class="Apple-converted-space"> </span>(Store x-container-attr-* headers in container db.)<o:p></o:p></span></p><p style="margin-right: 0cm; margin-bottom: 9.6pt; margin-left: 0cm; font-size: 12pt; font-family: 'Times New Roman', serif; line-height: 13.5pt; "><span lang="EN" style="font-size: 9pt; font-family: Arial, sans-serif; color: rgb(51, 51, 51); ">And some tests…<br><a href="https://review.openstack.org/51245" style="color: purple; text-decoration: underline; ">https://review.openstack.org/51245</a><span class="Apple-converted-space"> </span>(Container-forwarding unit and functional tests)<o:p></o:p></span></p><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US"> </span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN" style="font-size: 9pt; font-family: Arial, sans-serif; color: rgb(51, 51, 51); ">Regards,<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN" style="font-size: 9pt; font-family: Arial, sans-serif; color: rgb(51, 51, 51); ">Alistair Coles, Eric Deliot, Aled Edwards<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span> </span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 9pt; ">HP Labs, Bristol, UK<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 9pt; ">-------------------------<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 8pt; ">Hewlett-Packard Limited registered Office: Cain Road, Bracknell, Berks RG12 1HN .
