Hi, I know that this question might look silly, but I really need to know how the cassandra stress tool works.
I developed my data model and used Cassandra-Stress tool with "u" option where you pass your own data-model for column family (Table in CQL )and distribution of each column in the column family. Then I run it but when I compare the "latency" of it with what I could get from simple measurement of the time it took to execute a read/write operation for 1000000 cases. I could see that the results of Stress-Tool is much more (100 times) than what I have obtained in my own code. I know that stress test should stress the system and thus higher rates (.e.g. read/write latency) is reasonable, but 100 time more????? I am sure I am missing something in interpreting the results of Stress-Tool (mainly the "concept" of latency). But there is very little vague documentation there. I do appreciate of any one could help me to understand the output of Stress-Tool? BTW, I have already seen this one (but still the documentation is quite poor): http://www.datastax.com/documentation/cassandra/2.1/cassandra/tools/toolsCStressOutput_c.html best, /Shahab
