Description
When there is a large number of skip writes on an object,and each time only a few bytes are written, the OC will send an operation containing tens of thousands of write requests, causing OSD processing to time out.
So,i think wo can add an configuration item ,When the number of requests for an object on the OC reaches 1000,We force this object to be flushed from the OC.
