| <p>For each disk, keeps track if the context is on this disk's queue, indicating the disk must do some work for this context. The disk needs to do work in 4 cases: 1) in_flight_ranges is not empty, the disk needs to read for this reader. 2) next_range_to_start is NULL, the disk needs to prepare a scan range to be read next. 3) the reader has been cancelled and this disk needs to participate in the cleanup. 4) A write range is added to queue. In general, we only want to put a context on the disk queue if there is something useful that can be done. If there's nothing useful, the disk queue will wake up and then remove the reader from the queue. Doing this causes thrashing of the threads. </p> |

The reader pulls from the queue in FIFO order, so the ranges from different disks are round-robined. When the range is pulled off the ready_to_start_ranges_ queue, it sets this variable to NULL, so the disk knows to populate it again and add it to ready_to_start_ranges_ i.e. it is used as a flag by DiskIoMgr::GetNextScanRange to determine if it needs to add another range to ready_to_start_ranges_. </p> |

| <p>For each disk, the number of threads issuing the underlying read/write on behalf of this context. There are a few places where we release the context lock, do some work, and then grab the lock again. Because we don't hold the lock for the entire operation, we need this ref count to keep track of which thread should do final resource cleanup during cancellation. Only the thread that sees the count at 0 should do the final cleanup. </p> |
