Hello, Jeesoo.

I was investigating it exactly.

It means,when RPC service does not return a status
for a defined period of time,
the value is incremented.
(cassandra.yaml:rpc_timeout_in_ms)
(default:10000)

Therefore,
The Drop is assumed that,
there is a possibility that distribution node is completed processing,
and there is a possibility of having failed.

So, I recommend checking the data on a distribution node.


** I hope tomorrow will be a good day **
