software.1.Become familiar with Cassandra
2.Install Cassandra on your computer (Windows, Linux, Mac)
3.Create and load a Cassandra database
4.Perform several basic operations against your Cassandra databaseCapture screen shots to show evidence of having completed assigned operations (1 – 10)
described below. Number each screen shot with the number of the assigned operation/task (1 –
10).
Number each screen shot and include some text to describe the task accomplished which is
visible in the screen shot. Assemble (Copy & Paste) all screen shots and text into a document.
Save the document as a PDF.Use the submission link in the Project Assignment section of the Week 15 Moodle — which is

Appendix A –Windows InstallationThe first step is to download the software you’ll need for your Windows machine.
https://academy.datastax.com/planet-cassandra//cassandraNote: Download the latest one 3.9.0 Version but this one will not support DataStax OpsCenter as
it was removed by Apache. You have to download it separately. Instruction given below but it’s
optional.
Optional: DataStax makes available the DataStax Community Edition, which contains the latest
community version of Apache Cassandra, along with the Cassandra Query Language (CQL)
utility, and a free edition of DataStax OpsCenter, which is the tool you’ll want to use for
managing and monitoring your Cassandra cluster on Windows. To get Datastax Community
Edition, go to the downloads page and select the Windows installation package for your version
of Microsoft Windows. Note that 32 and 64-bit installers are offered.I’ll show you How to install Apache Cassandra on a Ubuntu 16.04. Apache Cassandra is a
NoSQL database management system which is free and open-source. It allows managing large
amounts of data with high availability without compromising the performance. Installing Apache
Cassandra on Ubuntu 16.04 is an easy task, just follow the steps bellow and you should have it
done in few minutes.The documentation is available at http://cassandra.apache.org/doc/latest/ and will help you to
learn how to configure and use the service for your projects.
First of all, connect to your Linux server via SSH, update the package index and upgrade all your
installed software to the latest version available. You can do that by using the following
commands: More Information
sudo apt-get update
sudo apt-get upgrade
Install Java 8 on Ubuntu 16.04To install Java 8 on your Ubuntu 16.04 VPS run the following command:
sudo apt-get install default-jdk
To verify that Java 8 is installed you can use:
java -versionThe output should be very similar to the one below:
openjdk version “1.8.0_131” OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-
0ubuntu1.16.04.2-b11) OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)
Install Apache Cassandra on Ubuntu 16.04To install Apache Cassandra on your server, first you need to add the Cassandra repository. At
the moment of writing this tutorial, the latest stable release of Cassandra is 3.x.x. Therefore, run
the following command to add the Cassandra repository on your server:
echo “deb http://www.apache.org/dist/cassandra/debian 311x main” | sudo tee -a
/etc/apt/sources.list.d/cassandra.sources.listNext, add the Cassandra repository keys:
curl https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add – sudo apt-key adv —
keyserver pool.sks-keyservers.net –recv-key A278B781FE4B2BDA
Update the package index:
sudo apt-get update
Finally, install Apache Cassandra using the following command:
sudo apt-get install cassandraStart, Stop and Enable Apache Cassandra on Ubuntu 16.04
To start the Apache Cassandra service on your server, you can use the following command:
sudo systemctl start cassandra.service
To stop the service, you can use the command below:
sudo systemctl stop cassandra.serviceIf the service is not already enabled on system boot, you can enable it by using the
command below:
sudo systemctl enable cassandra.service
Appendix C – Installation on Mac
Mac Installation
If you use Mac OS X as your platform for development work, then you may be interested to
know how easy it is to use Apache Cassandra on the Mac. The following shows you how to
download and setup Cassandra, its utilities, and also use DataStax OpsCenter, which is a
browser-based, visual management and monitoring tool for Cassandra.DataStax makes available the DataStax Community Edition, which contains the latest
community version of Apache Cassandra, along with the Cassandra Query Language (CQL)
utility, and a free edition of DataStax OpsCenter. To get Datastax Community Edition, go to
Planet Cassandra and download both Cassandra and OpsCenter, and select the tar downloads of
both the DataStax Community Server and OpsCenter.You can also use the curl command on Mac to directly download the files to your machine. For
example, to download the DataStax Community Server, you could enter the following at
terminal prompt:
curl -OL http://downloads.datastax.com/community/dsc.tar.gz
Install Cassandra
Once your download of Cassandra finishes, move the file to whatever directory you’d like to use
for testing Cassandra. Then uncompress the file (whose name will change depending on the
version you’re downloading):
tar -xzf dsc-cassandra-1.2.2-bin.tar.gzThen switch to the new Cassandra bin directory and start up Cassandra
Now that you have Cassandra running, the next thing to do is connect to the server and begin
creating database objects. This is done with the Cassandra Query Language (CQL) utility. CQL
is a very SQL-like language that lets you create objects as you’re likely used to doing in the
RDBMS world. Type ./cqlsh in your bin directory to make sure the cassandra executable.These tasks are shown in detail in Mac environment. However, once you have installed the
software the tasks are pretty much the same regardless of platform. So even if you are running on
Linux or Windows, please read through the Mac environment to get a feel for these tasks.1. Create a keyspace (schema or “collection”) (4)
2. Use a keyspace (4)
3. Describe a keyspace (4)
4. Create and Describe a table (column family) (6)5. Insert a new row (4)
6. Create an index (4)
7. Update a value (4)
8. Add/Drop/Rename a column (9)
9. Run a select query (5)
10. Drop a table and Drop keyspace (4)All Cassandra commands are case-insensitive.
1) Create a keyspace
create keyspace sample_keyspace with replication={‘class’:’SimpleStrategy’,
‘replication_factor’:1};
Note: Once a keyspace is created, you can create column families (the primary data object in
Cassandra), insert data, query data, and more:If you want to study about different strategy in Cassandra and it’s replication factor, the link
below provided the detailed instruction. https://bit.ly/2zFc82h
What is a keyspace?A keyspace is a logical container for data tables and indexes. It can be compared to an Oracle
Schema or a SQL Server database. Keyspaces also define how the data is replicated to the
various nodes2) Use keyspace;
use sample_keyspace;
3) If you want to see all keyspaces in cassandra, just type describe keyspaces;
4) To Create a table
CREATE TABLE sample_keyspace.user_info (
email_id text PRIMARY KEY,
first_name text,
last_name text,
object_id uuid,
phone_no text);5) If you want to see all column family in cassandra, just type
describe tables;
6) Describe a table;
describe sample_keyspace;
7) Insert command
insert into cuwallet_platform.user_info(email_id, first_name, last_name, object_id, phone_no)
values(‘[email protected]’,’Ajay’,’Kedia’,d0b941ea-1efd-365e-a4fb4c9de7396840,’7202031694′);
8) Index Creation
CREATE INDEX IF NOT EXISTS index_name ON sample_keyspace.user_info(phone_no);
9) Update Command
update sample_keyspace.user_info set first_name = ‘Ajay’ where email_id =
‘[email protected]’;
10) Alter Command: More Info could be seen from this link:1) Add a column
alter table sample_keyspace.user_info add dob text;
2) Drop a column
alter table sample_keyspace.user_info drop dob ;
3) Rename a column : Only primary key column can be renamed.
alter table sample_keyspace.user_info rename email_id to emailId;
11) Select
Select * from sample_keyspace.user_info;
12) Drop a table
drop table sample_keyspace.user_info;
13) Drop a keyspace
drop keyspace sample_keyspace;
