Before revision:  This paper presents techniques for analyzing the download time of systematic availability codes considering the Fork-Join scheme for data access. Specifically, we consider the setup in which requests arrive for downloading individual data objects, and each request is replicated (forked) to the systematic server containing the object and all of its recovery groups.
After revision:  This paper presents techniques for analyzing the download time of systematic availability codes . These codes provide access to hot data through the systematic server containing the object and multiple recovery groups. When a request for an object is received, it can be replicated (forked) to the systematic server containing the object and all of its recovery groups.
