Hi, I am trying to benchmark our custom schema in Cassandra and I managed to run it. However there are couple of setting and issues which I couldn't find any solution/explanation for. I appreciate any comments. 1- The default number of warm-up iterations in stress tool is about 50000. I would like to reduce this number (due to my storage space limitations), but I couldn't find any input parameters to do this. I just wonder if this setting is possible ?
2- I did not understand well what does the output of cassandra stress tool mean? I read this http://www.datastax.com/documentation/cassandra/2.1/cassandra/tools/toolsCStressOutput_c.html, but . for example, what does "latency" means here? does it mean how long a read/write operation is delayed until it is executed? in this case, what is the measure for actual read/write operation? It seems that the documentation is outdated, there is an output parameter "partition_rate" which is not explained in documentation? best, /Shahab
