Limited block fetch

Limited block fetch guarantees the transfer of a minimum amount of data in response to each request from the requesting system.

With limited block fetch, a single conversation is used to transfer messages and data between the requester and server for multiple cursors. Processing at the requester and server is synchronous. The requester sends a request to the server, which causes the server to send a response back to the requester. The server must then wait for another request to tell it what should be done next.
