com.yahoo.ycsb.database.DB
A layer for accessing a database to be benchmarked. Each thread in the client will be given its own instance of whatever DB class is to be used in the test. This class should be constructed using a no-argument constructor, so we can load it dynamically. Any argument-based initialization should be done by init(). Note that YCSB does not make any use of the return codes returned by this class. Instead, it keeps a count of the return values and presents them to the user. The semantics of methods such as insert, update and delete vary from database to database. In particular, operations may or may not be durable once these methods commit, and some systems may return 'success' regardless of whether or not a tuple with a matching key existed before the call. Rather than dictate the exact semantics of these methods, we recommend you either implement them to match the database's default semantics, or the semantics of your target application. For the sake of comparison between experiments we also recommend you explain the semantics you chose when presenting performance results.
