Can you point me towards any guide you are following to do your benchmark?\r\n\r\nThat output is not the default anymore, I would suggest updating your YCSB version: https://github.com/brianfrankcooper/YCSB/releases, the new default is more readable.\r\n\r\nThat is the histogram output style. In a nutshell all of the operation times are put into a histogram and output at the end of the workload. So, what you can see from what yo posted is that there were 0 operations that took 991, 992,..., 1000 milliseconds. If you were to look at the beginning of the histogram you would see a lot of counts on the smaller numbers of the histogram.\r\n\r\nWhat version of Cassandra are you working with? The `cassandra-10` binding is for older versions of Cassandra, so just want to make sure you are using the correct binding.\r\n\r\nCan you send me a link to the guide or tutorial that you are using to do your YCSB benchmark? Thanks a lot."}}
