Azure batch insert - how to reduce response length?

Question

I use Azure client lib to perform batch inserts into Azure Table Storage. Everything works fine. But when I sniff requests using Fiddler I found that every response from azure is about 90KB. I've changed prefer header to "return-no-content", but the response is still over 60KB (when request is 50KB).

Is there any way to reduce response lenght? Just to be like 100B (HTTP 202 or something).

Answer 1

Per OData V3 protocol format that Azure Storage Table Service uses, a batch response body must structurally match one-to-one with the corresponding batch request body, such that the same multipart MIME message structure defined for requests is used for responses.

Setting echoContent to false (aka "Prefer: return-no-content") would ensure that entities themselves are not returned though as you also observed, therefore reducing the size of the response body.
