Apache Cassandra is an open-source Distributed Key-value storage system. It was initially developed by Facebook to store extremely large data. Cassandra is not a database, it is a hybrid non-relational database, similar to Google's bigtable. This article mainly introduces Cassandra from the following five aspects: Cassandra's data model, installation and preparat

We now have a three-node Cassandra cluster on 192.168.129.34, 192.168.129.35, 192.168.129.39, because we have 7199 ports on each node (JMX monitor Port), So we can use Jconsole to detect the state of these nodes. Open the Jconsole under%java_home%/bin, enter 192.168.129.34:7199 in the remote connection, and then click Connect: More Wonderful content: http://www.bianceng.cnhttp://www.bianceng.cn/database/extra/ So you can go to the Jconsole interf

Cassandra may not be interested in being a nosql, but it's fascinating to do certain jobs, as Netflix and Instagram two companies must know.Over the years, NoSQL participants, such as MongoDB, have gotten a lot of attention, but the halo of Apache Cassandra has faded, and Facebook, which created Cassandra, has given up on it, The community of

A while ago, Cassandra-0.7.0-beta1 was released, todayCodeAfter a rough look, we found that the main changes were as follows: 1. The keyspace and columnfamily in the data model can be dynamically modified: In earlier versions, If You Want To modify keyspace and columnfamily in Cassandra, you must stop Cassandra, modify the configuration file, and then rest

Recently, I tried to build a cloud storage platform. After constant comparison, I decided to use Cassandra as the underlying database. Here we record the learning process of Cassandra. Cassandra is a hybrid non-relational database with distributed, column-based structure and high scalability. Cassandra is not a databas

What is Cassandra?Apache Cassandra is known for its scalability and fault-tolerant distributed database systems. Cassandra originated from a project that Facebook originally created in Amazon Dynamo and Google BigTable, and has since grown into an open-source system that has been used extensively by companies like Apple and Netflix. The following are some of the

1. Background Cassandra uses a Distributed Hash table (DHT) to determine the nodes that store a data object. In the DHT, the nodes and Data Objects responsible for storage are allocated with a token. Token can only be set within a certain range. For example, if MD5 is used as the token, the value range is [0, 2 ^ 128-1]. Storage nodes and objects are arranged into a ring based on the token size, that is, the largest token is followed by the smallest
