Re: [Openstack] does swift support resume upload?
Currently I prefer to implement range post and the html5 or flex client should call an additional HEAD request with header info like "x-object-md5" or so to notify the server to calculate the whole file's new md5. For the post request just add "range" and "x-object-size" in the header. 2012/10/15 符永涛 > Hi Tong Li, > > Thank you for your info. I'll consider the large object support.

Re: [Openstack] does swift support resume upload?
Hi Tong Li, Thank you for your info. I'll considering the large object support. But I prefer range post or append node for my requirement is not large object but to improve user experience in the slow network environment. And I want to use html5 or flex to upload to swift object store. C urrently I have two options, one is to use the large object support build in swift (I don't prefer this since for me the segments is very slow there'll be too many segments which impacts the performance), another is to implement range post or append mode myself, it is not hard to implement but I encounter a problem of how to calculate the whole file's md5 without impact the performance(if only partial file content changes). 2012/10/15 Tong Li > I assume that you want to upload some pieces and later upload more, then > complete the object.

Re: [Openstack] does swift support resume upload?
I assume that you want to upload some pieces and later upload more, then complete the object. If that is the case, you can use the large data object upload which allows upload small pieces, after some time, upload more, eventually upload a manifest file to complete the object.
