QUESTION
In my application I need to iterate over the contents of a file to make hashes of fixed-size chunks of the file. The end goal is to implement Amazon Glacier's Tree Hash algorithm, I almost verbatim copied the code from their documentation.

to get an IMemoryOwner
that we can use to retrieve our scratch buffer. We need a Memory
to pass to the ReadAsync
call, so we pass the Memory
property of the IMemoryOwner
.
We then restructure the code to make use of the HashAlgorithm.TryComputeHash
method which accepts a ReadOnlySpan
as the source and a Span
as the destination. We do allocate a new array (rather than using the ArrayPool
) since you are keeping/storing the arrays.

Answered 2019-Aug-14 at 01:27The code above works fine as I stated earlier in the post. I finally read amazon glacier documentations and I found out the any uploaded files can show up within 1 to 48 hours depending on the archived region. The archieved has been showed. it seems to take us-east region to archive the inventory after 8-9 hours since uploads. Thanks

I'm trying to upload a 600mb .zip file to glacier using the multipartupload function of the node version of the aws-sdk. I figured out how to read the file as a buffer and start the upload using a script from the aws docs.
The script starts an upload for each part of the file but each one fails with a 400 error.
