NoSQL is very strong recently because of the spring after the rain. Those of us who engage in traditional relational data management and development must keep up with the pace of the cloud era. Let's go into the world of Cassandra like learning from ABC.

I summed up so many keywords, linked together, although not around the earth, can give you a microcosm of what the Cassandra database is.

KeyWords of Cassandra

First of all, Cassandra is a NoSQL database, column-oriented storage, a database based on Google Big Table and Amazon Dynamo, which was developed by FaceBook and later developed into an open source Apache project; Java language development, the source code can be found online.

As for me, instead of predicting or commenting on the advantages and disadvantages of each database, I went to learn and enter Cassandra with a heart of awe and humility.

Extract the Cassandra to the appropriate directory, such as / u01/apache-cassandra-2.1.2

Configuration / etc/profile file (path is configured for csh to run)

Export JAVA_HOME=/usr/java/jdk1.7.0_45

Export CASSANDRA_HOME=/u01/apache-cassandra-2.1.2

Start cassandra to the CASSANDRA_HOME / bin/ directory

Cd $CASSANDRA_HOME / bin/

. / cassandra
