CCM2: A Python repository from haochenpan

benchmark workflow

start Cassandra and YCSB servers on GCP (requires Ubuntu 16.04 or above)
install CCM2 for each of them (see below)
update cassandra.yaml (see below)
if the implementation needs some changes in a java file, do so, and run ant in ~/cassandra to build again
start each Cassandra server: cd ~/cassandra && ./bin/cassandra -R
at a Cassandra server, check node join: cd ~/cassandra && ./bin/nodetool status
use cqlsh to create the column family ycsb and the table usertable (see below)
generate ycsb commands (see below) and run each command shown on a ycsb server
run fuser -k 7199/tcp on each Cassandra server to kill Cassandra
run ps -fe | grep java to check
run rm ~/cassandra/data ~/cassandra/logs -rf to completely remove data and log folders

install CCM2

# to install a branch recorded in ~/CCM2/py/setupCass.py
sudo su
sudo apt-get install -y git
cd && git clone https://github.com/haochenpan/CCM2.git
. ~/CCM2/sh/setup.sh bsr

# to install only ycsb
sudo su
sudo apt-get install -y git
cd && git clone https://github.com/haochenpan/CCM2.git
. ~/CCM2/sh/setup.sh no-cass

update cassandra.yaml

# step 1: modify ~/CCM2/py/conf.py to set parameters

# step 2:
python3 ~/CCM2/py/changeYaml.py

create the table

# select a internal ip from shown in ./notetool status
cd ~/cassandra &&  ./bin/cqlsh <internal-ip> -e "CREATE KEYSPACE ycsb WITH REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor': <num-of-servers>};"
cd ~/cassandra &&  ./bin/cqlsh <internal-ip> -e "CREATE TABLE ycsb.usertable ( y_id varchar primary key, field0 varchar);"

#e.g.
./bin/cqlsh 10.142.0.30 -e "create keyspace ycsb WITH REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor': 1};"
./bin/cqlsh 10.142.0.30 -e "CREATE TABLE ycsb.usertable(y_id varchar PRIMARY KEY, field0 varchar);"

# different implementations requires different schemas, see https://github.com/haochenpan/CCM#cassandra-table-schemas

generate ycsb commands

# assume parameters in modify ~/CCM2/py/conf.py are set
# step 1: modify ~/CCM2/py/ycsb.py to set parameters 

# step 2: try
python3 ~/CCM2/py/ycsb.py load 3 5
python3 ~/CCM2/py/ycsb.py run 3 5

# step 3: try
python3 ~/CCM2/py/ycsb.py # to see the help message

switch Cassandra version

# to remove the cassandra folder and reinstall a branch
python3 ~/CCM2/py/setupCass.py base
python3 ~/CCM2/py/setupCass.py bsr

# just switch a branch and recompile
python3 ~/CCM2/py/setupCass.py bsr no-rm
python3 ~/CCM2/py/setupCass.py base no-rm
