1. Create Keyspace

CREATE KEYSPACE micropy
WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 }
AND DURABLE_WRITES = True;

2. Use Keyspace

USE micropy;

3. Create Table

CREATE TABLE actions (
  uid int,
  action int,
  timestamp varchar,
  PRIMARY KEY (uid, timestamp, action)
);

4. Query

SELECT * FROM actions;

1. Unit testing (requests + unittest)
2. Continuous Integration
