Hey rajeev, what kinda practical implementation u want ?
- Rajeev Ranjan12y ago
  Not too much vast things , as we know about the NoSql database,(replication, performance tunning, tunnable, multiple seed nodes,) something like that

  sorry of i asked something wrong, but usually, when i read books i started see, examples then read how does author described that example.

Dear Abhishek , your article is such a knowledgeable article indeed. whatever you were written there can you show me (like practically) , cuz one of my frnd asked me same , and i wasn't prove it. It would be a kind help for me , if you can .

Introduction

This article will discuss the base of Apache, Cassandra, and Cassandra 2.0 by comparing them. Here I am also including some new features that are available in Cassandra 2.0.

This article is the first in a series.

What is Apache Cassandra?

Apache Cassandra is a scalable open-source NoSQL database. It is used for managing or handling a humongous amount of data. This humongous amount of data can be of any type (Structured, Unstructured, or Semi-structured) among various data centers and the cloud too.

Why Apache Cassandra?

Cassandra works like a free and handy architecture. It sports the same nodes. Here are some features that you need to know in order to answer, why to use Apache Cassandra

Continuous data availability
Linear Scalability
Operational simplicity
Works simply with every commodity server
No single point of failure
Powerful dynamic data
Maximum flexibility
Fast respond times
Automatic database distribution
High-performance rate

How Apache Cassandra Works?

As I mentioned above that Apache Cassandra works with all the same level nodes, in other words, there is no secondary level in it. Cassandra provides automatic distribution of data across all the nodes available in that database cluster.

There is nothing related to the programming that a developer or database admin needs to do. There is no coding required to distribute data across a cluster because data is already portioned across all the nodes in a cluster.

What's new in Cassandra?

Key features of Cassandra 2.0 are as follows

It supports lightweight transactions
There is a new serial consistency level
Use of the IF keyword in CQL

There are several other new features in Cassandra 2.0.,

Drop Column Support

Authentication

Is improved and modified
SASL support added
CQL native protocol

Bind Variable support

Better server-side parsing
Execution is performed using a BATCH message
It contains a list of query strings.
There is no reparsing in it.

Triggers

It supports TRIGGERS, which helps in firing an event that executes a set of programmatic logic, that generally runs inside or outside a database cluster.

Triggers

Index Enchantments

Compaction improvement
Off heap partition

Some other base changes in Apache Cassandra 2.0 are as follows

There are several new commands for disabling background compactions.
Cqlsh COPY command for giving support to the collections.
Use of NATIVE PROTOCOL version in the system local table.
Support for an empty list of values.
Useful in Java DRIVER applications.
AUTO BOOTSTRAPPING functionality.
