Semen Boikov commented on IGNITE-3810:
--------------------------------------
As I understand the purpose of 'maxWriteQueueSize' is throttling (avoid file
writer overload when there are to many writes), it defenetely should not case
hangs. We can fix it this way: if value size is large than 'maxWriteQueueSize'
print warning that this paremeter should be increased, then such large values
should just wait when write queue is empty.
> FileSwapSpaceSpi can hang when large value is written
