Hi James/Haomai/Xiaoxi, I spent some more time on the fio-objectstore branch, and pushed an update. In testing, I realized that it was using the io_unit's start time to name the objects, which meant that every write operation was creating a separate object. In addition to fixing this to use fio's filenames for object names, I also added support for the open_file() and close_file() functions. It now creates objects of the proper size on startup, so read-only jobs will work normally. It also removes its objects on exit. On startup, it no longer calls create_collection() if it already exists, so I was able to re-run fio jobs over and over again without having to clear the data directory (tested with FileStore and KeyValueStore).
