I am performing a data migration from an un-sharded Azure Cosmos MongoDB (source) account to a sharded Azure Cosmos MongoDB account (sink). One of my collections in the source has ~250k documents. When running the dmt tool, I am running into a cursor not found exception when migrating this particular collection:
Data transfer failed
MongoDB.Driver.MongoCursorNotFoundException: Cursor <id> not found on server <fqdn:10255> using connection <connection_id>
The community forum has a few recommendation as mentioned here. I have tried to reduce BatchSize but in vain. I would like to have the ability to disable cursor timeouts. Is this possible to implement with the current implementation of the C# driver?
In addition, I've always noticed that this exception gets thrown at the 18000th record exact (I have reproduced this 3 times). That being said, I am not sure if it's really due to 10 minute cursor timeout...
