Patent number: 10515029Abstract: Techniques for facilitating conversion of an application from a block-based persistence model to a byte-based persistence model are provided. In one embodiment, a computer system can receive source code of the application and automatically identify data structures in the source code that are part of the application's semantic persistent state. The computer system can then output a list of data types corresponding to the identified data structures.Type: GrantFiled: November 18, 2016Date of Patent: December 24, 2019Assignee: VMware, Inc.Inventors: Vijaychidambaram Velayudhan Pillai, Irina Calciu, Himanshu Chauhan, Eric Schkufza, Onur Mutlu, Pratap Subrahmanyam
