cassandra dashboard

Summary This paper mainly introduces the index in Cassandra, materialized view, some knowledge points need to have a basic understanding of Cassandra to understand. such as how the data is distributed in the Cassandra node. If there is something you don't understand, you can read the article before this column. or send me an email and discuss cnstonefang@gmail.c

Kubernetes1.5 Integrated DashboardConfiguring the Kubernetes dashboard is relatively straightforward. Similarly, only need to obtain the Dashboard-controller.yaml and Dashboard-service.yaml files from the source code, slightly modify can:wget Https://rawgit.com/kubernetes/kubernetes/master/cluster/addons/dashboard/

A Brief introduction　　For those who are accustomed to the relational database, learning Cassandra has some difficulties. Cassandra has a lot of new terminology, and the terms in relational db are similar but inherently different. Here we mainly learn the Cassandra data model from two angles: bottom-up and top-down.Two-bottom-up understanding of the data model of

Solandra can be seen from the alias. In fact, it integrates the real-time search engine program of SOLR and Cassandra. Its features are as follows: Supports most of SOLR's default features (search, faceting, and highlights) Data replication, sharding, caching, and compression are all performed by Cassandra. Multi-master (any node can be read and written) High real-time performance. You can read it afte

1. Inverse entropyThe Cassandra database draws on Amazon's Dynamo in a distributed architecture, and references Google's bigtable on the data storage model. So in the data consistency and dynamo and BigTable have a deep connection, inverse entropy mechanism is a manifestation of this connection. inverse entropy, like the gossip protocol, is an algorithm based on infectious disease theory, which is mainly used to ensure that data on different n

Recently installed Cassandra to the product server, a lot of things require a lot of strict, such as Perf used in the JMX, previously as long as the IP can access, but the product server is not, so there is a security risk, nodetool-h host can add and delete nodes. So the thing to talk about today is Cassandra JMX's authorization and access control. Here is the first, the most common use of passwords and a

These reports allow database administrators to quickly determine if bottlenecks exist in their systems and whether bottlenecks are occurring, and capturing these additional diagnostic data can be more helpful in resolving problems. Fo

1. Basic Configuration First, you need to prepare 3 or more computers. The following assumes 3 computers running a Linux operating system with IP addresses of 192.168.0.100, 192.168.0.101, and 192.168.0.102. The system needs to install the Java runtime environment and then download the 0.7 version of the Cassandra binary release package here. Select one of the machines to start the configuration, first expand the

A preface　　In the previous article, I briefly described the installation and launch of Cassandra on the Windows platform, and described the basic data model of Cassandra in a bottom-up perspective. Before I learn a new thing, I think the best way to do this is to get to the macro and start with the details. This article analyzes the Cassandra data model from a to

Administrators and developers in SharePoint 2010 may be familiar with SharePoint Developer Dashboard (developer Dashboards). The tool has been widely rewritten in SharePoint 2013 and has become increasingly available in your troubleshooting (troubleshooting) Toolkit.

Document directory Advantages and disadvantages of Cassandra Reprinted: http://hi.baidu.com/qnuth/blog/item/8720811ff79bca11314e15da.html Because the data models of hbase and Cassandra are very similar, we will not compare the data models between them here. Next we will mainly compare the data consistency and multi-Copy Replication features of both parties. Hbase Hbase ensures write consistency. When

Objective: Read a lot of Cassandra cluster configuration data, a lot of information will always make people foggy feeling ah, had to write an article about the basic implementation of Cassandra cluster configuration.

This article is the first of the Cassandra Data Model design (all two), which contains some of the practices ebay uses to design the Cassandra data model. Some of the best practices we learned through our communities, some of which are new to us, and some that are still controversial, may benefit from further practice. In this article, I will explain some basic practices as well as a detailed example. Even
