Answer
Yield points allow MongoDB to pause long operations to let other operations acquire locks, preventing system stalls.
Quick Answer
Yield points are moments during a long-running query when MongoDB pauses to check for interrupts and allow other operations to run. Without yields, a long collection scan could hold resources indefinitely. MongoDB yields automatically at regular intervals (every 128 documents by default). This prevents any single query from starving other operations, but it means cursors can see changes made during their execution.
