Hi,
Some of the DEV team is complaining about dropping empty MV is taking a long time,
The error they are reporting is:
Caused by: com.datastax.driver.core.exceptions.OperationTimedOutException: [/10.30.50.3:9042] Timed out waiting for server response at com.datastax.driver.core.RequestHandler$SpeculativeExecution.onTimeout(RequestHandler.java:954) at com.datastax.driver.core.Connection$ResponseHandler$1.run(Connection.java:1575) at io.netty.util.HashedWheelTimer$HashedWheelTimeout.expire(HashedWheelTimer.java:670) at io.netty.util.HashedWheelTimer$HashedWheelBucket.expireTimeouts(HashedWheelTimer.java:745)
When I check the logs I just see the messages below:

I didnt find much information about it, any idea on it? Could it be related to NodeSync ?
I'm using DSE 6.8
