 This is in contrast to chunked access, such as for example formatting and parsing entire JSON or XML texts or entire Java Object serialization graphs.The space and performance scaling of an ItemSpace is smooth as any size of client-imposed multi-Item structure is created, grows, shrinks, or disappears.On-storage performance is like any block-oriented B-tree, with blocks of about 4 KB, which is "O"(log("n")) per access.
