| Description |
|
DBClientCursor will implement the client side of the exhaust cursor OP_MSG protocol when commands are being used and QueryOption_Exhaust is requested.
As part of this work, we will remove OP_QUERY exhaust support from DBClientConnection. This is currently used only by the database cloner, so the only effect of this will be to cause a performance regression when cloning between 4.0 and 4.2, and the commands which use the database cloner are deprecated. |
