If data the changes with each request, you should never compress it if you are trying to optimize server CPU load, but you should compress it if you are trying to optimize bandwidth usage -- either can be your bottleneck / expensive resource. Effectively, this allows you to expose a mechanism allowing users to securely upload data .

You can create small objects as segments and upload them as one large object by using a manifest object. When copying data from REST APIs, normally, the REST API limits its response payload size of a single request under a reasonable number; while to return large amount of data, it splits the result into multiple pages and requires callers to send consecutive requests to get next page of the result. But don't make the false assumption that you can . The last two steps are intersperse([, ,, ]) and .runFold()((acc, e) acc + e).
