Hi, 
the Javadoc (or source code) of the me.prettyprint.hector.api.factory.HFactory class contains all the examples to create keyspaces and column families.

To create a keyspace:

String testKeyspace = "testKeyspace"; 
KeyspaceDefinition newKeyspace = HFactory.createKeyspaceDefinition(testKeyspace);
cluster.addKeyspace(newKeyspace);


To create a column family and a keyspace:

String keyspace = "testKeyspace"; 
String column1 = "testcolumn";
ColumnFamilyDefinition columnFamily1 = HFactory.createColumnFamilyDefinition(keyspace, column1);
List<ColumnFamilyDefinition> columns = new ArrayList<ColumnFamilyDefinition>(); 
columns.add(columnFamily1);

KeyspaceDefinition testKeyspace =
HFactory.createKeyspaceDefinition(keyspace, org.apache.cassandra.locator.SimpleStrategy.class.getName(), 1, columns);
cluster.addKeyspace(testKeyspace);

Hi All,

I am using Hector client for cassandra . I wanted to know how to create keyspace and column family using API's to read and write data.
or  i have to create keyspace and column family manually using command line interface.
