Cassandra YCSB benchmarking by value size

gistfile1.txt

CASS_HOST=#host ip here
sec=90
records=100000

for threads in 10 20 40 50
do
    for size in 10 1000 10000
    do
         # reset Cassandra on remote host here; something like
         ssh ubuntu@$CASS_HOST "pkill -9 java;  rm -rf /mnt/md0/cassandra/; cassandra &; disown"
         sleep 10
         bin/cassandra-cli -h $CASS_HOST -f setup-cass-ycsb.cql
         bin/ycsb load cassandra-10 -P workloads/workloada -p hosts=$CASS_HOST -p fieldlength=$size -p fieldcount=1 -p recordcount=$records -s
         bin/ycsb run cassandra-10 -P ../YCSB/workloads/workloada  -threads $threads -p maxexecutiontime=$sec -p hosts=$CASS_HOST -p fieldlength=$size -p fieldcount=1 -p operationcount=100000 -p recordcount=$records -s > TR$threads-TH$thru-S$size.txt
    done
done

where setup-cass-ycsb.cql is something like
create keyspace usertable
    with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy'
    and strategy_options = {replication_factor:1};
use usertable;

create column family data;

is needed at the end of setup-cass-ycsb.cql :)
