Facebook. These companies, through communication and sharing, revealing their infrastructure concepts, software practices, and data processing frameworks, have nurtured a vibrant open source software community that has evolved into enterprise technologies, systems and software architectures, as well as new infrastructure, DEVOPS, virtualization, cloud computing and software-defined networks.Inspired by Google File System (GFS), the open source distributed computing framework Hadoop and MapReduc

, but the concept of discussion is also crucial for measuring others. Scalability Scaling reading and copying is easy when we zoom in on this, we mean to write data that scales to automatic partitioning of multiple machines. We call for a system that is not sound, such as "distributed database." "This includes cassandra,hbase,riak,scalaris,voldemort, and so on. If you write volumes or data capacity more than one machine can handle, then these are your only options if you do not want to manually

provide caching and so on. You can run a MapReduce query on Couchdb via JavaScript. In addition, COUCHDB provides a very convenient web-based management console. It is ideal for Web applications.4. hypertableHypertable imitates Google's bigtable database system. Hypertable's creator will "become a highly available, petabyte-sized database open source standard" as the hypertable goal. In other words, Hypertable's design goal is to reliably store large amounts of data across multiple inexpensive

milliseconds, single-machine QPS at level 100,000 (related to data size and storage complexity) Some common types of nosql products K-v (Memcached,Redis), this kind of nosql products in the Internet industry the widest range of applications. Memcached provides K-V memory storage with LRU elimination policies, while Redis provides memory and persistent storage that supports complex structures (List, hash, etc.) Column (hbase,Cassandra), HBase is a distributed databa

MongoDB is a scalable, high-performance, open-source, document-oriented database. Neo4j is a graphical database and a complete transactional database for storing graphic data. All sub-projects of spring data support: Template Object and data storage ing Support for data access objects

database engine with no external dependencies, used as an embedded database on iphones, Firefox browsers and Skype, is widely used in devices like the iphone, It can also be deployed in desktop software such as Skype and Firefox. No configuration and management of the entire database is saved on a single disk file, growing to the widest range of languages supported by 7TB in Top 10 9 .

use different databases. Applications produce different kinds of data, and relational databases are not necessarily the best choice. In some scenarios, a NoSQL database might provide a more convenient data model, providing more performance and scalability. For example, an application that produces and queries strings takes a character search engine such as Elasticsearch. Similarly, an application that generates social image data can take a picture database, for example,

big data analysis project focuses not on big data, but on big data analysis technologies and methods. Big Data analysis requires high-performance massive data processing capabilities and reasonable response time. To meet these conditions, some non-traditional technologies have emerged over the past 10 years and are good at sharing nothing, large-scale parallelism, and horizontal scaling.1.3.
