How to create Cassandra Keyspace
Table of Contents
In this article, I am going to show How to create Cassandra Keyspace. A keyspace in Cassandra is a namespace that defines data replication on nodes. A cluster contains one keyspace per node.
Syntax
CREATE KEYSPACE <identifier> WITH <properties>
CREATE KEYSPACE “KeySpace Name” WITH replication = {'class': ‘Strategy name’, 'replication_factor' : ‘No.Of replicas’};
Example:
CREATE KEYSPACE narayanatutorial WITH replication = {'class': 'SimpleStrategy', 'replication_factor' : '1'};
Keyspace Commands
- CREATE KEYSPACE − Creates a KeySpace in Cassandra.
- ALTER KEYSPACE − Changes the properties of a KeySpace.
- DROP KEYSPACE − Removes a KeySpace
- USE – allows to change the current keyspace
