The Zen of Python, by Tim Peters

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.

Primary Keys

A single column Primary Key is also called a Partition Key.

When Cassandra is deciding where in the cluster to store this particular piece of data, it will hash the partition key. The value of that hash dictates where the data will reside and which replicas will be responsible for it.

Assuming that the following environment variables are set:

• KAFKA_HOME where Kafka is installed on local machine (e.g. /opt/kafka)
• ZK_HOSTS identifies running zookeeper ensemble, e.g. ZK_HOSTS=192.168.0.99:2181
• KAFKA_BROKERS identifies running Kafka brokers, e.g. KAFKA_BROKERS=192.168.0.99:9092
