Cassandra tutorial

Setting up cassandra column families:

From Cassandra CLI:

1. create column family auth_failures WITH key_validation_class = 'UTF8Type' and default_validation_class='UTF8Type' AND gc_grace = 86400;
2. create column family cassandra_test WITH key_validation_class = 'UTF8Type' and default_validation_class='UTF8Type' AND gc_grace = 86400;
3. create column family Files with comparator = 'CompositeType(UTF8Type, UTF8Type, UTF8Type)' and key_validation_class = 'UTF8Type' and default_validation_class = 'UTF8Type';
4. create column family sample_entity WITH key_validation_class = 'UTF8Type' and default_validation_class='UTF8Type' AND gc_grace = 86400;

All class assumes cassandra node is active on localhost, default port: 9160, keyspace: hr

Build:

mvn clean install assembly:single
