Cassandra import & export
1 min readCassandra.csv file data:

Create keyspace and create tables and then importing the data form local system to Cassandra:
$./bin/nodetool status
$./cqlsh 192.168.0.104
Cqlsh>CREATE KEYSPACE test_keyspace WITH replication = {‘class’:’SimpleStrategy’, ‘replication_factor’:1};
Cqlsh>use test_keyspace;
Cqlsh>CREATE TABLE test_csv_import (car_make text, car_model text, start_year int, id int, first_name text,last_name text, department text, PRIMARY KEY(car_make, car_model, start_year,id);
Below are copied csv data from local system:
Cqlsh>COPY test_csv_import(car_make, car_model,start_year, id, first_name,last_name,department) FROM ‘/home/jumpstartcs/Desktop/Cassandra.csv ‘WITH DELIMITER=’,’ AND HEADERS=TRUE;
Now we will export data from Cassandra to local file system:
