Hello, I've some questions about the handling of concurrent requests by Swift. Any help would be great:)
If I understand correctly, a PUT request on swift-proxy will be transmitted to at least half the storage nodes plus one, before returning the response. A subsequent GET request should have an updated version (because it also make the GET request to several storage nodes ?), but the listing is not immediately up-to-date.
Now, I wonder what happens when two PUT requests with 'If-Match' headers are executed at the same time. The 'If' header is active, and one of the two requests is rejected ? Or the header is ignored, and the request with the last timestamp wins ?
I search a way to ensure I can't lose a version of the files without noticing it.
I'll take any idea. Thanks all! -- Kévin Bernard-Allies _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
