cassandra column family table,cassandracolumn


Whether you use the keyword TABLE or COLUMNFAMILY, both are the same (synonyms). I guess the keyword TABLE was introduced with CQL3. So you can use either one in your statements.

Second question, adding DateType, you should use timestamp.

CREATE COLUMNFAMILY sample (rowkey text, ts timestamp, PRIMARY KEY(rowkey));

INSERT INTO sample (rowkey, ts ) VALUES ( '1','1366354711797');
// ts value is basically the System.currentTimeMillis(), I mean a long value

In cassandra keyspace or database are same,like wise columnfamily and table are just same.

Cassandra is more like Mysql In its syntax and supports hql(similar to sql)

A table in cassandra can be created like:

CREATE TABLE users (
user_name varchar,
password varchar,
gender varchar,
session_token varchar,
state varchar,
birth_year bigint,
PRIMARY KEY (user_name));
