QueryFailedException using ycsb to a sharded mongodb database #33

Open tdeneau opened 7 years ago

tdeneau commented 7 years ago

I am trying to use ycsb (thru the mongo async driver) to a MongoDb database sharded across 4 servers (not replicated). It seems to work for light loads but when the load gets heavier, I see errors such as: com.allanbank.mongodb.error.QueryFailedException: Operation aborted.

How do I eliminate these kinds of errors?

Note: I have never had such problems accessing a non-sharded single MongoDB instance from YCSB,
