Error: Invalid paramerter user

Answer 1

The mixed & user modes are mutually exclusive. You need to remove mixed ratio\(write=5,read=1\) n=100000 part, specify queries & inserts inside the .yaml file, and then specify necessary ration as ops parameter, for example as: ops\(insert=3,read1=1\) n=100000
