wiredtiger/wiredtiger.github.com — Issue #134: Add a "no I/O" flag to file cursors
Author: wiredtiger

State: open

Applications may prefer for some low priority or low latency operations to fail rather than trigger I/O. Add a configuration to WT_SESSION::open_cursor that makes operations fail rather than wait for I/O.

Open question: should the I/O be scheduled before failing the operation to permit a kind of read-ahead?
